RECENT RESULTS (LAST 10)

STARTING PITCHERS

Kyle Leahy (R), St. Louis: Leahy is 10-4 with a 3.41 ERA, 1.33 WHIP, 124 strikeouts, and 38 walks across 132.0 innings in 27 starts. Among NL pitchers with at least 60 innings, his ERA ranks 35th of 114 -- above the league average of 3.92 -- while his 6.8% walk rate ranks 30th of 114, better than the league average of 8.2%, and his 52.4% ground-ball rate ranks 32nd of 114. His WHIP of 1.33 ranks 74th of 114, in the below-average band. The story of his season splits at handedness: Leahy holds right-handed batters to a .593 OPS across 258 batters faced (55th of 232 NL pitchers with at least 60 batters faced vs. right-handers), while left-handed batters have posted a .864 OPS against him across 301 batters faced (185th of 219). At home this season his ERA sits at 2.91 (54th of 185 NL pitchers with at least 20 innings at home); on the road it rises to 3.94 (88th of 178 NL pitchers with at least 20 innings away).

Sean Newcomb (L), Chicago White Sox: Newcomb is 2-4 with a 2.71 ERA, 1.13 WHIP, 74 strikeouts, and 29 walks across 83.0 innings. Three of his four starts came with an opener ahead of him, making his per-start figures a thin base: he has pitched into a third pass in none of his four starts, and his 2026 per-pass sample is too small across those outings to compare across times through the order. His splits show modest separation by handedness: right-handed batters have posted a .590 OPS against him across 204 batters faced; left-handed batters have posted a .615 OPS across 135 batters faced. At home his ERA is 2.08 across 43.1 innings; away it is 3.40 across 39.2 innings.

Chris Murphy -- 2026-09-07: Chicago White Sox activated LHP Chris Murphy from the 15-day injured list.

On the Cardinals side, JJ Wetherholt (right wrist tendinitis) remains on the injured list, leaving a gap at second base tonight. Masyn Winn returned from the injured list September 8 and is back at shortstop. Andre Pallante, activated from the 15-day injured list September 4, is back in the rotation.

For the Chicago White Sox, Tommy Pham (left calf strain) is on the injured list, thinning their outfield options. Davis Martin, back from the 15-day injured list since September 2, is available in the rotation. Kyle Teel was activated September 4 and returns to the catching role. Chris Murphy, activated from the 15-day injured list September 7, is back as a rotation option for Chicago.

2A: BVP -- CARDINALS BATTERS VS OPPONENT STARTER

Small sample: Masyn Winn (3 PA), Thomas Saggese (2 PA), Jordan Walker (2 PA), Iván Herrera (2 PA), Nathan Church (1 PA), José Fermín (1 PA).

Every career BvP entry in this table is noise -- the largest sample is Masyn Winn's 3 PA, and the remaining five batters have faced Sean Newcomb no more than twice. No career BvP figure here carries enough weight to project tonight. Alec Burleson, Joshua Báez, and Leo Bernal have no career BvP on file against Newcomb; no figures apply for them tonight.

No danger threshold is triggered -- no Cardinals batter has reached the 10 PA minimum required. The matchup tonight is effectively a blind one for the full lineup; his 2026 platoon work against left- and right-handed batters is the better surface to lean on.

Bench note: No significant bench BvP history.

2B: BVP -- OPPONENT BATTERS VS CARDINALS STARTER

Small sample: Brenton Doyle (3 PA), Miguel Vargas (1 PA), Jake Rogers (1 PA), Edgar Quero (1 PA), Chase Meidroth (1 PA).

Career BvP history between Kyle Leahy and this Chicago White Sox lineup is thin across the board. Brenton Doyle is 1-for-3 (.333/.333/.333) in the deepest file, while Miguel Vargas, Jake Rogers, and Edgar Quero are each 0-for-1. Chase Meidroth has one plate appearance against Leahy -- a walk -- leaving his batting line blank. No member of the lineup has faced him enough times to draw a meaningful pattern; tonight will be a first real look for most of the order.

2C: PLATOON SPLITS -- CARDINALS

2026 companion columns: sample floor is 60 PA vs LHP (below floor renders SSS in the table above). Above that floor the 2026 vs-hand figure leads the read, with 2025 as the historical anchor; below it, 2025 leads.

Jordan Walker and Iván Herrera are the Cardinals' strongest individual matchups against Sean Newcomb tonight. Walker is stronger against left-handed pitching this season, posting a .916 OPS across 164 PA vs. LHP, ranking 23rd of 166 NL hitters with at least 200 plate appearances overall (.829 OPS; league average .731). Herrera is also stronger against left-handed pitching this season, at .781 OPS across 206 PA vs. LHP.

The lineup's six right-handed bats -- Fermín, Herrera, Walker, Báez, Saggese, and Winn -- land on Newcomb's tougher side: he has allowed a .615 OPS to left-handed batters this season compared with .590 to right-handed batters. Fermín and Winn are each stronger against left-handed pitching in 2026 (.747 OPS and .745 OPS, respectively), but both sit below the NL average of .731 overall. Saggese's 2026 vs.-LHP sample of 44 PA is too small to report split rates reliably; his 2025 line vs. LHP reads .273/.279/.348 across 68 PA.

The two left-handed bats fall on Newcomb's stronger side. Alec Burleson is stronger against right-handed pitching this season (.947 OPS) and carries a .545 OPS across 192 PA vs. left-handed pitching in 2026. Nathan Church is stronger against right-handed pitching this season (.677 OPS) and shows a .586 OPS across 94 PA vs. LHP this year. Leo Bernal bats from the right side against a left-handed starter; his 2026 sample against left-handed pitching is too small to compare (13 plate appearances).

2C: PLATOON SPLITS -- OPPONENT

2026 companion columns: sample floor is 60 PA vs RHP (below floor renders SSS in the table above). Above that floor the 2026 vs-hand figure leads the read, with 2025 as the historical anchor; below it, 2025 leads.

Kyle Leahy's 2026 split runs heavily in his favor against right-handed batters, holding them to a .593 OPS across 258 batters faced -- six of Chicago White Sox's nine lineup spots are right-handed, landing the majority of the order on that side. The two switch-hitters add texture: Braden Montgomery (.731 OPS vs. right-handed pitching, compared with .478 vs. left-handed pitching this season) bats from the left side against Leahy and sits on his stronger split; Edgar Quero (.560 OPS vs. right-handed pitching, compared with .515 vs. left-handed pitching this season) also flips left, though the gap is narrow. Colson Montgomery is the lineup's lone left-handed bat (batting fourth at SS); his 2026 line vs. right-handed pitching reads .190/.--/.-- across 409 PA at a .675 OPS, below his .811 OPS against left-handed pitching this season, so he arrives at Leahy's weaker side (.864 OPS allowed vs. left-handed batters) without the platoon advantage the split would suggest for the group. Among the right-handed bats, Jake Rogers (.500 OPS across 124 PA vs. right-handers in 2026) and Brenton Doyle (.509 OPS across 107 PA) profile as the lineup's lightest contact threats against Leahy's stronger side; Miguel Vargas (.778 OPS across 453 PA) and Chase Meidroth (.667 OPS across 428 PA) are the more active right-handed presences in the order.

2D: PITCHER PLATOON SPLITS

Kyle Leahy faces a White Sox lineup built almost entirely of right-handed bats -- six of nine starters bat right-handed, with one left-handed bat (Colson Montgomery) and two switch-hitters (Edgar Quero, Braden Montgomery). That alignment lands heavily on Leahy's stronger side: 2026 vs right-handed batters, he has allowed a .593 OPS across 258 batters faced. Against left-handed batters this season he has allowed a .864 OPS across 301 batters faced -- a gap consistent with last season's pattern, when his figures read .589 OPS vs right-handed batters and .701 OPS vs left-handed batters across 200 and 163 plate appearances, respectively. Montgomery's left-handed at-bats are the lone platoon exposure the lineup presents tonight.

Sean Newcomb draws a Cardinals lineup with six right-handed bats, two left-handed bats (Alec Burleson, Nathan Church), and one switch-hitter (Leo Bernal). Newcomb's 2026 split runs closer than it did a year ago: he has allowed a .590 OPS against right-handed batters across 204 batters faced and a .615 OPS against left-handed batters across 135 batters faced this season. Last season the split ran the other way, with right-handed batters the softer side (.720 OPS allowed across 270 plate appearances, against .629 vs left-handed batters across 121), so the 2026 split has both narrowed and reversed. This season's numbers are the current read: Burleson and Church, the two left-handed bats, land on the side that has been marginally softer in 2026, and neither side carries a pronounced platoon advantage.

2D-HA: PITCHER HOME/AWAY SPLITS

Kyle Leahy takes the mound at home tonight, the side where he has been stronger this season: batters have posted a .708 OPS against him at Busch Stadium, compared with .769 on the road. His 2026 home ERA of 2.91 ranks 54th of 185 NL pitchers with at least 20 innings pitched at home. Last season the split ran the other way -- his 2025 away ERA (2.68 across 173 batters faced) was well below his 2025 home ERA (4.47 across 190 batters faced) -- but the 2026 numbers put him clearly in home-friendly territory this year.

Sean Newcomb is working the road tonight, his weaker side in 2026: batters have posted a .609 OPS against him away compared with .592 at home, and his away ERA of 3.40 trails his home mark of 2.08. Last season Newcomb's pattern was similar -- a 2025 away ERA of 2.57 across 171 batters faced against a 2025 home ERA of 4.47 across 220 batters faced -- though that historical edge ran in the opposite direction. Both pitchers enter working against the less favorable side of their splits; in Leahy's case that means the home ground aligns with his stronger 2026 numbers, while Newcomb faces the same alignment in reverse.

2E: TTO SPLITS (TIMES THROUGH ORDER)

Kyle Leahy has pitched into a third pass in 21 of 27 starts. In the 21 starts he pitched into a third pass, hitters posted a .789 OPS on the second pass -- 188 PA. From the third pass on in those same starts: 1.017 OPS -- 92 PA. Early hooks: 6 starts, 34 PA. Sean Newcomb has pitched into a third pass in 0 of 4 starts. Early hooks: 4 starts, 0 PA. Per-pass rate stats resting on fewer than 50 PA render as their PA count, never as a decimal; 2026 companion columns carry their own 60 BF floor (below floor renders SSS).

Kyle Leahy has pitched into a third pass in 21 of 27 starts. In those 21 starts, hitters posted a .587 OPS against him on the first pass (245 batters faced in 2026) and a .789 OPS on the second pass (188 PA in the starts he continued through). From the third pass on in those same starts: a 1.016 OPS across 92 PA. The step from second to third pass is the critical window -- Leahy remains manageable through two turns but absorbs significantly more damage if he stays in for a third.

Sean Newcomb has pitched into a third pass in 0 of his 4 starts, three of which began with an opener. His 2026 first-pass sample is 29 batters faced, too small to report split rates reliably. His 2025 first-pass line across 287 PA was a .676 OPS; his second pass across 81 PA was .795. The 23-PA third-pass sample from 2025 falls below the floor for rate reporting. With Newcomb's current role carrying limited starter innings, his times-through-order pattern is not yet established in 2026.

2F: INHERITED RUNNERS PROFILE

Kyle Leahy leads this group in inherited-runner volume with 29 on his 2025 ledger, stranding 62.1% -- below the four pitchers shown here but the busiest workload in the group. Gordon Graceffo's 2025 strand rate of 54.5% is the lowest in the table across 11 inherited runners. Riley O'Brien has handled 10 inherited runners and stranded 70.0%, the closest to the league baseline of the four. Michael McGreevy has converted all three of his 2025 inherited-runner entries, posting 100.0% -- though his sample of 3 is the smallest in the group. Each pitcher's strand figure carries a 2026 companion in the columns to the right: Leahy's 132.0 IP / 3.41 ERA / 1.33 WHIP, Graceffo's 74.0 IP / 2.68 ERA / 1.07 WHIP, O'Brien's 59.0 IP / 3.97 ERA / 1.25 WHIP, and McGreevy's 154.0 IP / 3.92 ERA / 1.25 WHIP reflect their current 2026 form. 2025's league average strand rate was 68.8%, a historical baseline drawn from a proxy source that does not expose inherited runners at the team level.

Hitter Batted Ball Results (2025) -- CWS

Sample floor is 50 balls in play (PROVISIONAL): below floor renders "--" in the table above -- cite the raw BIP/AB count instead of the rate.

Both starters share a similar 2025 contact shape: Kyle Leahy induced ground balls on 44.2% of balls in play across 249 BIP, with fly balls at 26.9% and line drives at 27.7%. Sean Newcomb ran a nearly identical profile -- 46.9% ground balls, 25.6% fly balls, and 26.0% line drives across 258 BIP. Either starter on the mound, the White Sox lineup is more likely to produce ground balls than any other contact type.

The matchup consequence falls on ground-ball average. Most of the Chicago lineup hits ground balls modestly: Luisangel Acuna batted .270 on grounders across 74 AB in 2025, Chase Meidroth .279 across 201 AB, and Edgar Quero .267 across 146 AB. Brenton Doyle (.250 across 168 AB) and Miguel Vargas (.229 across 118 AB) are closer to league-average on the ground. Colson Montgomery (.206 across 63 AB) and Randal Grichuk (.171 across 82 AB) are the quieter ground-ball bats in the group. Jake Rogers has fewer than 50 balls in play on record in each batted-ball type, so no rate applies tonight.

Line drives are where this lineup does its real damage, for those with enough sample. Doyle batted .575 on line drives across 80 AB, Meidroth .560 across 84 AB, Quero .632 across 76 AB, and Vargas .574 across 101 AB. Grichuk (48 AB on line drives) and Montgomery (36 AB) fall below the 50-AB floor, so no rate is published for either. Acuna's 31 line-drive AB also sits below the floor. On fly balls, the group is suppressed across the board: Doyle .131 across 99 AB, Grichuk .123 across 73 AB, Montgomery .115 across 52 AB, Meidroth .058 across 86 AB, Quero .090 across 67 AB, and Vargas .101 across 169 AB. Acuna's 29 fly-ball AB falls below the floor. The contact shape both starters induce -- ground-ball heavy, fly-ball light -- lines up with the contact type this lineup handles least productively.

2H: BATTERY PAIRING

Yohel Pozo and Jimmy Crooks, both shown in the 2025 battery table, are not on the current Cardinals active roster. Leo Bernal, tonight's scheduled catcher, does not appear in the table -- he and Kyle Leahy carry no shared 2025 history on file, making this a fresh battery. Ivan Herrera appears in the table from his time catching Leahy in 2025 (4 G, 3.0 IP, 6.00 ERA, .308 AVG), but he is in tonight's lineup at DH, not behind the plate.

Among the catchers with 2025 history, Pedro Pages -- the other catcher on the active roster -- owns the largest sample: 43 games and 62.0 innings with a 3.05 ERA and .225 AVG against. Yohel Pozo's 13-game, 16.0-inning line (2.25 ERA, .259 AVG) was the strongest ERA in the table but comes from a catcher no longer on the roster. With Bernal catching tonight, that prior data has no direct carry-over to this pairing.

2I: BASERUNNING MATCHUP

White Sox baserunning threats: Miguel Vargas leads the White Sox runners in tonight's lineup with 18 stolen bases and a 90.0% success rate in 2026. Luisangel Acuña has added 16 steals at 72.7% (22 attempts) in 2026. Brenton Doyle has 12 steals at 75.0% (16 attempts) in 2026. Chase Meidroth has 3 steals and 2 caught stealings in 2026 -- his sample of 5 attempts is too small to report a rate. Colson Montgomery has 1 steal and 1 caught stealing in 2026 (2 attempts, too small for a rate). Edgar Quero has 1 steal and no caught stealings in 2026 (1 attempt, too small for a rate). Jake Rogers has 1 steal and no caught stealings in 2026 (1 attempt, too small for a rate).

Cardinals catcher -- Leo Bernal starts tonight. Bernal has allowed 9 stolen bases against 2 caught stealings in 11 attempts in 2026; his sample is too small for a published rate. Pedro Pages, the primary Cardinals catcher this season, carries a 30.9% caught-stealing rate across 55 attempts in 2026.

Opponent catcher -- Jake Rogers starts for the White Sox. Rogers has caught 11 of 44 basestealing attempts in 2026, a 25.0% rate. Edgar Quero has caught 11 of 42 attempts (26.2%) and Kyle Teel 7 of 26 attempts (26.9%) on the season.

2J: DEFENSIVE CONTEXT

All figures are 2025. Masyn Winn at shortstop is the infield anchor: 129 games, 64 double plays turned, and a .994 fielding percentage on 3 errors. Thomas Saggese slides into second base tonight, where his 2025 sample of 35 games shows 24 double plays and a .973 fielding percentage on 4 errors -- he also logged 33 games at shortstop (.988) and 18 at third (.939) last season, giving him range across the infield. Alec Burleson takes first base, where he played 50 games in 2025 with 27 double plays and a .990 fielding percentage; he adds 41 games in left field at a clean 1.000 and 34 in right at .983 in the same season. Jordan Walker is in right field tonight, his primary 2025 outfield home: 108 games, .981 fielding percentage on 4 errors. Nathan Church in center field showed a clean 1.000 over 18 games there in 2025. José Fermín is at left field tonight; his 2025 fielding record shows 4 games in left at 1.000 and 15 at second base (1.000, 5 double plays). Joshua Báez, also listed at left field in tonight's card, has no 2025 fielding record in the table; no defensive figures apply to his position tonight. Leo Bernal at catcher has no 2025 fielding record on file; no defensive figures apply to his start tonight. Iván Herrera is at designated hitter tonight; his 2025 catching record (14 games, 1 error, .989) is a past-sample figure and does not apply to tonight's role.

2K: BALLPARK CONTEXT & HEAD-TO-HEAD

The Cardinals have gone 6-3 against the Chicago White Sox across the 2022-2025 stretch, winning each of the last three matchups in 2025 and splitting or winning each prior season in that range.

2L: BATTER K%/BB% PROFILE

Cardinals

Jordan Walker's 2026 K% stands at 25.0% across 615 plate appearances, down from 31.8% in 2025, though still above the league average of 22.1%. Thomas Saggese carries a 2025 K% of 28.1% and a 2026 mark of 26.4% across 129 plate appearances. Nathan Church's 2025 K% of 27.7% reflects a small 65-PA sample; his 2026 figure has settled at 17.5% across 422 plate appearances. José Fermín's 2026 K% of 13.0% runs well below the league average of 22.1%. Iván Herrera's 2026 K% of 18.3% also sits below the league average of 22.1%, pairing with a 2026 BB% of 10.6%. Alec Burleson and Masyn Winn both carry 2026 K% figures in the 17–21% range with modest walk rates.

White Sox

Facing Kyle Leahy, the White Sox lineup has several pronounced contact-and-strikeout stories. Colson Montgomery's 2025 K% was 29.3% across 283 plate appearances; his 2026 K% has climbed to 34.9% across 587 plate appearances. Brenton Doyle's 2025 K% of 25.7% has risen to 32.8% in 2026 across 186 plate appearances. Jake Rogers posted a 2025 K% of 27.5% and a 2026 mark of 29.1% across 165 plate appearances. Miguel Vargas provides contrast: his 2026 K% of 17.8% across 639 plate appearances sits below the league average of 22.1%, and his 2026 BB% of 13.8% is well above the league average of 8.9%. Chase Meidroth's 2026 K% of 22.2% is just above the league average of 22.1%. Luisangel Acuña carries a 2026 BB% of 3.8% across 209 plate appearances, and Randal Grichuk's 2026 BB% of 3.8% across 234 plate appearances is similarly low.

2M: BATTER BATTED BALL PROFILE

Cardinals

Sean Newcomb's 2025 contact shape leaned ground-ball heavy at 46.9% GB, with fly balls at 25.6% and line drives at 26.0% across 258 balls in play. Five Cardinals starters have publishable contact-shape figures. Iván Herrera generates ground balls at a 52.6% rate across 285 BIP -- the highest among the group -- and projects well against a pitcher who induces grounders at an above-league rate. Jordan Walker sits at 48.9% GB and 29.4% FB across 231 BIP. Alec Burleson and Thomas Saggese carry more balanced profiles: Burleson at 42.0% GB / 33.4% FB / 24.6% LD across 398 BIP, Saggese at 41.8% GB / 29.6% FB / 28.6% LD across 189 BIP. Masyn Winn's 2025 profile shows 39.6% GB and 34.0% FB across 376 BIP -- the flattest ground-ball rate in the group, against a starter who suppresses fly-ball contact. José Fermín (46 BIP) and Nathan Church (37 BIP) are below the 50-BIP floor; no contact-shape rates apply for either tonight.

White Sox

Sample floor is 50 balls in play (PROVISIONAL): below floor renders "--" in the table above -- cite the raw BIP/AB count instead of the rate.

Kyle Leahy's 2025 contact shape ran 44.2% GB, 26.9% FB, and 27.7% LD across 249 balls in play -- a ground-ball tilt that aligns with his 2026 ground-ball rate of 52.4%, above the league average of 47.0%. Miguel Vargas stands apart from the White Sox group with a fly-ball-heavy profile: 30.4% GB and 43.6% FB across 388 BIP. That fly-ball tendency runs against a starter who suppresses fly-ball contact; Vargas also enters having shown splits running .964 OPS against left-handed pitching compared with .778 OPS against right-handed pitching this season, but Leahy is a right-hander. Chase Meidroth and Luisangel Acuña are among the group's most pronounced ground-ball hitters at 54.2% GB (371 BIP) and 55.2% GB (134 BIP), respectively -- contact shapes that fit comfortably against Leahy's profile. Brenton Doyle (48.4% GB, 347 BIP) and Edgar Quero (50.5% GB, 289 BIP) follow a similar ground-ball lean. Randal Grichuk (40.4% GB / 36.0% FB, 203 BIP) and Colson Montgomery (41.7% GB / 34.4% FB, 151 BIP) show moderate fly-ball rates relative to the group. Jake Rogers carries a publishable profile at 81 BIP: 44.4% GB / 33.3% FB / 22.2% LD.

2N: PITCHER K%/BB% PROFILE

The 2025 figures show both starters in a similar zone: Sean Newcomb posted a 23.3% strikeout rate against a 7.9% walk rate across 92.1 innings, yielding a 2.94 K/BB ratio, while Kyle Leahy ran a 22.0% strikeout rate and a 7.7% walk rate across 88.0 innings for a 2.86 K/BB ratio. Their 2026 profiles tell slightly different stories. Leahy's walk rate this season is 6.8% -- above average among NL pitchers with at least 60 innings, 30th of 114 against a league average of 8.2% -- and his strikeout rate of 22.2% sits at the league-average tier (52nd of 114; league average 22.3%). Newcomb's 2026 strikeout rate of 21.8% runs just below the league average of 22.1%, and his walk rate of 8.6% runs just below the league average of 8.9%.

KEY MATCHUPS

Leahy third-pass exposure. Kyle Leahy has pitched into a third pass in 21 of 27 starts this season. His 2026 first-pass OPS allowed sits at .587; by the third pass, that figure rises to 1.016 -- a structural cliff that arrives reliably when the lineup turns over a third time. The CWS lineup is 6-of-9 right-handed or switch, which lands on Leahy's stronger platoon side, but that advantage is contingent on Oliver Marmol keeping him short enough to avoid the third turn. If the game runs deep and Leahy works into a third pass, that cliff is the Cardinals' largest structural risk tonight.

Newcomb vs. Cardinals right-handed order. Sean Newcomb's stronger side this season is against right-handed batters. Six of the nine Cardinals bats are right-handed -- Jordan Walker (.799 OPS vs. RHP across 451 PA), Iván Herrera (.721 OPS vs. RHP across 455 PA), and José Fermín among them -- so the bulk of the St. Louis order enters on his stronger side without a platoon edge. Fermín faces the sharpest split disadvantage: .747 OPS against left-handers versus .577 against righties, a difference carried across samples of 153 and 186 PA.

Leahy home advantage vs. CWS right-handed order. Kyle Leahy carries a 2.91 ERA at Busch Stadium this season, 54th of 185 NL pitchers with at least 20 innings pitched at home, against a 3.94 ERA on the road (88th of 178). The home setting pairs with a CWS lineup that is 6-of-9 right-handed -- Leahy's stronger platoon side. Miguel Vargas (.778 OPS vs. RHP across 453 PA) and Brenton Doyle (.509 OPS vs. RHP across 107 PA) are the named right-handed bats tonight; Doyle's 2026 line against right-handed pitching is the weaker of the two, and he has struck out in 32.8% of his 186 plate appearances this season.

Newcomb opener role -- no TTO2/TTO3 data. Sean Newcomb has been used as an opener in 3 of his 4 starts this season and has reached a second pass in no starts, leaving Cardinals batters without any second-or-third-time-through exposure to plan against. The per-pass sample from those 4 starts -- 29 batters faced in TTO1 alone -- is too small to report split rates reliably. The structural question for St. Louis is how much damage they can do early, before the Chicago bullpen takes over.

WATCHLIST

-- Kyle Leahy. If Kyle Leahy is sent out for a third pass tonight, the bullpen decision becomes the sharpest inflection point of the game; his third-pass numbers are the night's primary structural risk. Watch whether Oliver Marmol pulls him before that turn arrives.

-- Nathan Church. If Nathan Church reaches base tonight, watch whether he extends his 10-game hitting streak.

-- Colson Montgomery. If Colson Montgomery reaches the plate late in the game with Kyle Leahy still on the mound, watch whether Oliver Marmol pulls him -- Montgomery is the one left-handed bat in the order, and a late plate appearance against Leahy is the matchup the Threat above describes.
