MLB Bullpen Fatigue Analysis
Bullpen fatigue is one of the most undervalued factors in baseball betting. Tired relievers show measurably worse performance, and smart bettors can exploit overworked bullpens, especially in F5 to full game total differences and late-game live betting.
Key Betting Applications
- Game Totals: Fatigued bullpens (score 60+) correlate with 0.5-1.0 higher runs in late innings.
- F5 vs Full Game: If one bullpen is exhausted, the full game line may be undervalued vs F5.
- Live Betting: Watch for value on overs when a fatigued team goes to their pen in the 6th-7th.
- Series Context: Third game of a series after two extra-inning games = prime regression spot.
