Why we made this MLB moneyline pick

Sized at 1u — confidence 70, due to a clear pitching advantage for the Mariners despite negative EV. The Pinnacle fair line for the Mariners is -136, indicating a -3.6% EV at the current best price of -148. The line has moved against the Mariners since opening, but has stalled in the last 2 hours. The Mariners' starting pitcher, Logan Gilbert, has a significantly lower ERA (3.29 vs 4.48), a better WHIP (1.01 vs 1.40), a higher IP (93.0 vs 84.1), and a higher K/9 (9.68 vs 7.04) compared to the Guardians' Slade Cecconi. Gilbert also shows strong recent form with ERAs of 1.42, 1.29, and 1.50 in his last three starts, clearly outperforming Cecconi's 3.00, 1.59, and 3.60. The team's L10 RS/g and RA/g are significantly better for the Mariners compared to the Guardians (2.3 RS/g and 3.7 RA/g vs 3.2 RS/g and 3.9 RA/g), indicating a better recent overall team performance. Both bullpens are fresh, and both teams are on 0 days rest. The park, Progressive Field, is pitcher-friendly (Run 95, HR 92), which favors the stronger pitcher. The DATA_CONFIDENCE is 78/100, which is good. Despite the negative EV, the statistically superior starting pitcher and overall team form make the Mariners the side with the clearest edge. [SIGNALS FIRED] 5 pattern(s), 2 cluster(s) → deterministic confidence 63 (BASIC, expected ROI -21.5%): • MLB_SP_ERA_EDGE — 38.2% WR (n≈35): Starting pitcher run-prevention gap gives our side a real baseball edge • MLB_SP_PARK_STACK — 54.4% WR (n≈280): Pitcher profile and park traits stack in our favor • MLB_SP_L3_EDGE — 54.1% WR (n≈300): Recent starting pitcher form supports our side more than the market is pricing • DATA_CONFIDENCE_LOW — 42.4% WR (n≈33): Missing data lowers certainty; keep confidence capped • CLV_PRIOR_NEGATIVE — 45.1% WR (n≈610): Similar signals have historically lost closing-line value, so this edge is less trustworthy [RISK] YELLOW: MLB_SP_ERA_EDGE has 38.2% WR but only ~35 data points | YELLOW: DATA_CONFIDENCE_LOW has 42.4% WR but only ~33 data points | YELLOW: Mean historical WR 46.9% ≤ implied 59.7% — thin edge vs price
