statcast_pitcher_exitvelo_barrels

Analyze pitcher performance by retrieving exit velocity and barrel rates allowed. Identify pitchers who limit hard contact using metrics like average exit velocity, barrel percentage, and hard-hit rate.

Instructions

Get exit velocity and barrel rate allowed by pitchers.

Returns average exit velocity, barrel percentage, and hard-hit rate allowed. Lower values indicate a pitcher who limits hard contact.

Args: year: Season year (e.g. 2024). min_batted_ball_events: Minimum batted ball events against (default 50). player_name: Optional. Filter to one pitcher (e.g. 'Gerrit Cole').

Great for finding pitchers who suppress hard contact most effectively.

Implementation Reference

src/statcast_mcp/server.py:977-1012 (handler)

The implementation of the `statcast_pitcher_exitvelo_barrels` tool, which fetches exit velocity and barrel rate data using `pybaseball` and formats the results.

    year: int,
    min_batted_ball_events: int = 50,
