Matt Chapman

Career vs E-Rod (LHP): 29 PA, .333 AVG, 1.039 OPS, 1 HR — the deepest and strongest career BvP sample for any SF hitter in this game. Chapman posts a .796 OPS vs left-handed pitching, his favorable platoon side. He has 7 HR in 2026 with consistent power production. Chase Field HR park factor is 1.08. While E-Rod's 2.27 ERA makes this a tough night for the Giants offense overall, Chapman's LHP platoon edge and 29-PA career history with over 1.000 OPS against Rodriguez make him the best anytime HR candidate in the lineup at +450.

Chapman is 2-for-32 over his last 9 games (.063 AVG) and Giants manager Tony Vitello publicly flagged approach issues — hitters 'reaching and feeling for the baseball.' Career vs Elder: 8 PA, .286 AVG, 0.661 OPS with 0 HR — below-average matchup even before the slump. Elder's 2026 ERA of 3.71 and ground-ball profile suppress contact. Chapman's L7d OPS of 0.350 confirms the slump is active. Market prices under at only +116 — meaningful value.

Career vs López: .167 AVG, 0.440 OPS in 22 PA — a meaningful sample showing consistent struggles. 2026 head-to-head: 1 PA, 0.000 OPS this series. Season slash .242/.333/.381 and L7d OPS of 0.397 (ice cold). Oracle Park runs factor 0.93 suppresses offense. At +104 this is genuine value given BvP history.
