Masyn Winn

Winn is 3-for-20 (.150 AVG, 0.350 OPS) across 20 career PA vs Skenes — the deepest sample of any STL batter in this matchup and a consistent signal across multiple seasons. In 2026 specifically: 2 PA, 0.000 OPS. His season slash of .235/.310/.321 is already modest, and Skenes has suppressed him at every opportunity. The career sample here is large enough to draw real conclusions. At -114, the market is nearly 50/50 on this, creating value on the under relative to the historical data.

Winn is 1-for-6 (.167 AVG, 0.334 OPS) lifetime vs Irvin. Year-over-year trend is not encouraging: 0.000 OPS in 3 PA in 2024, 0.666 OPS in 3 PA in 2025 — both well below league average. His season line of .235 BA with just a 0.596 OPS vs RHP makes him one of the weaker bats in the lineup against right-handers. Irvin's K rate (~8.97 K/9 season) suppresses contact. Under 0.5 hits at +112 carries real edge for a hitter who historically struggles against this arm.

Winn posts a .237 season AVG with a .598 OPS vs RHP — one of the weaker right-handed matchup profiles in the Cardinals lineup against Roupp (RHP). His 2026 BvP vs Roupp: 2 PA, 0.000 OPS (small sample, but represents his full 2026 exposure). L7d OPS is .467, making him one of the coldest bats on the roster. Market prices Under at +108, near-even odds — but Winn's platoon disadvantage, cold recent form, and 0-for-2026 BvP record tilt the probability meaningfully toward no hit.
