Sep 22, 2026 ET · Odds at publication 2.0400
0-for-4 career vs Bradley with 0.000 OPS across both 2025 (2 PA, 0.000 OPS) and 2026 (2 PA, 0.000 OPS). Season .215 AVG against RHP with .513 OPS — among the weaker contact profiles in the SF lineup. Bradley's elite K/9 (10.41) compounds the contact risk. Under at +104 offers slight positive value over market's implied 49.0%.
Jun 9, 2026 ET · Odds at publication 1.9300
Career vs Martinez: 6 PA, .167 AVG, 0.500 OPS, 0 HR. Critically, 2026 specifically vs Martinez: 3 PA, 0.000 OPS (0-for-3). Season: .222/.281/.311 — one of the weaker bats in the BOS lineup. Martinez's 2.29 ERA this season with strong control (13 BB/70.2 IP) suppresses weak contact hitters. At -108, this under offers near coin-flip price on a player who is 0-for-3 vs today's starter in 2026.
May 29, 2026 ET · Odds at publication 2.1200
Mayer is hitting .218/.278/.299 in 163 PA. L7d OPS: 0.364. L28d OPS: 0.453 — an extended cold stretch. Against RHP (Cecconi) his OPS is just 0.559. With no career BvP data vs Cecconi and his current extended slump, the under at +112 (implied 47.2%) offers positive expected value.
