Lines & ParlayLab picks
How ParlayLab grades this matchup
ParlayLab's methodology engine projects each MLB game with a market-blended model combining team offense (season + L14 rolling RPG and OPS), starting pitcher form (ERA, WHIP, K%, home/road splits), ballpark factors (per-handedness HR and run multipliers), weather (wind direction relative to center field, temperature, precipitation), bullpen fatigue, and Statcast contact quality. Outputs are a moneyline, run-line, and total projection — each graded HIGH / MED / LOW confidence based on edge versus the FanDuel line.
