Cardinals win 6-0 behind a six-run fifth and a near-untouchable McGreevy line. McGreevy: 6.0 IP, 1 H, 0 R, 9 K, 2 BB. Graceffo and Stanek closed it without allowing a hit. Herrera went 4-for-5; Burleson and Church added two hits each. The fifth-inning rally turned on Wetherholt's bases-clearing single (capped by a Tatis fielding error that brought Wetherholt all the way around), Gorman's RBI single, and a Winn sac fly.

BOTTOM LINE
Edge: Cardinals run 5 LHB tonight (Wetherholt, Burleson, Gorman, Church, Scott) into Vásquez's softer side -- his 2025 vs-LHB line is .264 AVG / .358 OBP / .406 SLG / .764 OPS, vs RHB it is .232 / .289 / .363 / .652. Burleson's 2025 vs-RHP line is .296 / .353 / .478 with 15 HR over 419 PA -- the cleanest individual platoon edge in tonight's report.

Threat: Manny Machado is 9-for-33 (.273 AVG, .515 SLG) with 2 HR over 35 career PA off May -- the largest opponent BvP sample on the slate, and a profile of consistent contact (only 6 K) plus genuine power. May's vs-RHB aggregate (.711 OPS) does not soften this individual matchup.

Watch: May's TTO2 cliff. First pass through the order: .226 AVG / .347 SLG / .652 OPS in 2025. Second pass: .290 / .508 / .878. Third pass: .882 OPS. Innings 4-6 are where the Padres' lineup most likely opens the door, and May's career road ERA (6.28 vs 3.24 at home) compounds the concern at Petco tonight.
KEY MATCHUPS
Burleson vs Vásquez. Burleson's 2025 vs-RHP line is .296 / .353 / .478 with 15 HR over 419 PA. Vásquez allows .764 OPS to LHB vs .652 to RHB. The 1-for-7 career BvP is too small to override the platoon read.
Machado vs May. 9-for-33 (.273 AVG, .515 SLG, 2 HR) over 35 career PA -- the largest opponent-side BvP sample tonight. Machado has produced power without striking out (6 K in 35 PA), and his 2025 19.3% K% means May's whiff path is narrow.
May TTO2 window vs SD. Innings 4-6 are May's 2025 vulnerability: .290 AVG / .508 SLG / .878 OPS on the second pass through the order. Combine with May's 6.28 career road ERA at Petco -- the middle innings are the likeliest Padres scoring window.
WATCHLIST
-- Sheets and Merrill vs May. Two LHB power profiles into May's worst-handedness side (.852 OPS allowed to LHB in 2025, 15 HR). Sheets 2025 vs RHP: .250 / .323 / .452, 17 HR. Merrill 2025 vs RHP: .279 / .336 / .514, 15 HR. Watch innings 4-6 specifically.
-- Tatis SB threat with fresh battery. Tatis 32 SB / 7 CS career (82.1% success). Pagés has 0 prior IP paired with May -- pop-time and signal sequencing are not yet calibrated.
-- Bullpen fork. Romero 88.5% strand vs Svanson 50.0% on 26 inherited runners each. Which arm gets called with traffic decides the middle-inning math.
-- Vásquez K-rate lift. 2026 to date 22.4% K% vs 2025 baseline 13.7%. If it holds, the Cardinals' contact assumption against Vásquez resets.
