A starter usually throws between 90 and 100 pitches per game before the manager pulls him. That «pitch count» is watched closely to protect the pitcher’s arm and prevent injuries.
The 100-pitch limit
100 is the classic benchmark: near it, a pitcher loses velocity and command to fatigue, and the bullpen comes in. Going past 120 pitches is very rare today, though in past decades starters threw far more.
Why it’s protected
Pitching is a brutally demanding motion on the elbow and shoulder. Overloading the arm leads to serious injuries, like the one that requires Tommy John surgery. That’s why teams guard their pitchers with pitch limits and rest days between starts.
