Baseball Pitcher: Roles, Types, Techniques, and Performance Metrics
Overview of baseball pitchers: roles from starters to closers, pitch types and techniques, rule constraints and enforcement, and key performance metrics like ERA, strikeouts and pitch counts.
In the sport of baseball, the pitcher is the player who delivers the ball to the opposing team's hitter and plays a central role in every defensive play.
A typical play begins with the pitcher throwing a baseball from the pitcher's mound toward the catcher. The pitcher's aim is to retire the batter—preventing them from reaching base—either by inducing a strikeout, producing an out from a batted ball, or forcing a weak contact that the defense can field cleanly. Batters attempt to reach base by hitting the ball or earning a base on balls (a walk).

Roles and types
- Starting pitchers typically begin the game and are expected to pitch for multiple innings.
- Relief pitchers enter after the starter and may pitch for short stints; they include specialists such as middle relievers and setup men.
- Closers are relievers who often pitch in the final inning to protect a narrow lead.
Skills and techniques
Pitchers use a variety of grips and arm actions to create different pitches—fastballs, curveballs, sliders, changeups and others—that vary in speed, movement and batter deception. Effective pitching combines physical attributes (arm strength, command, endurance) with mental skills (strategy, sequencing, reading hitters).
Rules and measurements
The distance from the pitching rubber to home plate is standardized in professional play, and the mound and delivery restrictions are governed by the rules of the game. Umpires enforce violations such as balks and illegal pitches that can affect baserunners or nullify plays.
Statistics and evaluation
Pitchers are assessed using several statistics that measure run prevention, control and dominance—examples include earned run average, strikeouts, and walks allowed. Teams manage pitchers' workloads through rotations and pitch counts to reduce injury risk and maintain performance.
