Our model combines six advanced sabermetric metrics (wOBA, FIP, Pythagorean Win%, DER, OPS, BABIP) with starting pitcher matchups, bullpen strength, recent team performance, and injury data. These components are weighted and converted to win probabilities using a sigmoid function.
Picks are generated once starting pitchers are confirmed, typically by early afternoon ET. Final picks lock in 15 minutes before each game's first pitch with the latest data refresh.
Moneyline: Pick the team to win outright.
+1.5 Run Line: The team wins or loses by only 1 run.
-1.5 Run Line: The team wins by 2 or more runs.
