BOTTOM LINE
Edge: Leahy on the road into a heavy RHB pool. The Padres roster pool is 9 RHB / 3 LHB and Leahy's 2025 line vs RHB is .238 / .270 / .319 / .589 OPS. Add a 2.68 2025 away ERA vs 4.47 home and the splits stack toward a strong outing.

Threat: Manny Machado. He homered yesterday and carries a 1-for-3 BvP vs Leahy with 1 K. 2025 vs RHP: .279 / .332 / .440 with a 19.3% K%. He will not strike himself out.

Watch: Leahy's second pass through the order is unmapped -- only 8 PA in 2025 (.125 / .250 / .375). Innings 4-6 are where the game gets defined; the unknown is whether Leahy holds up after the SD lineup gets a first look.
KEY MATCHUPS
Burleson vs Buehler. 2-for-2 lifetime BvP, 1.000 AVG / 1.000 SLG (small 2 PA sample). 2025 vs RHP: .296 / .353 / .478. 2026 RISP: .347 AVG / .940 OPS. The cleanest LHB profile vs Buehler-vs-LHB.
Leahy vs Tatis. Tatis 0-for-2 lifetime BvP. 2025 vs RHP: .277 / .366 / .466 with 12.9% BB%. 32 SB / 82.1% success in 2025 -- a baserunning lever any time he reaches.
Buehler vs the LHB stack. 5 LHB projected (Wetherholt, Burleson, Gorman, Church, Scott). Buehler 2025 vs LHB: .300 / .390 / .440 / .830 OPS vs .221 / .317 / .433 / .750 vs RHB. Handedness aligns on Buehler's weak side.
WATCHLIST
-- Buehler TTO1 power. .279 / .452 / .816 OPS in 2025 first pass through the order, 9 HR in 236 PA. Innings 1-3 are when his slug allowed peaks.
-- Leahy TTO2 unmapped. Only 8 PA in 2025 second pass through the order vs 355 PA in TTO1. The smallest sample on the report -- innings 4-6 will write that line.
-- Bullpen fork. Romero 88.5% strand on 26 IR vs Svanson 50.0% on 26 IR in 2025. Whichever arm enters with traffic decides whether STL holds a lead or loses one.
