Why we made this MLB spread pick

The Seattle Mariners look to have an edge with their starting pitcher Bryce Miller (ERA 1.58, WHIP 0.70) significantly outperforming the Pirates' Bubba Chandler (ERA 4.62, WHIP 1.38). Miller also has a clear edge in his last 3 starts with ERAs of 0.0, 0.25, and 0.2 while Chandler's were 0.33, 0.35, and 0.37. Pinnacle has a spread of -1.5 at +126, while FanDuel has a best price of +125, showing no clear EV. The line velocity is stalled for both sides, indicating no recent sharp action. The Mariners' L10 RS/g (2.3) is significantly lower than the Pirates' L10 RA/g (4.2), which is a concerning sign. However, the Mariners' bullpen is fresh, as is the Pirates'. The DATA_CONFIDENCE is 84/100. Sized at 1u — confidence is limited due to no EV and concerning L10 run scoring for the Mariners against Pittsburgh's RA. [SIGNALS FIRED] 3 pattern(s), 2 cluster(s) → deterministic confidence 73 (BASIC, expected ROI 22.0%): • MLB_SP_ERA_EDGE — 57.2% WR (n≈420): Starting pitcher run-prevention gap gives our side a real baseball edge • MLB_SP_L3_EDGE — 54.1% WR (n≈300): Recent starting pitcher form supports our side more than the market is pricing • STEAM_STALLED — 51.4% WR (n≈280): Sharp move exhausted; fade the overextended direction
