Legends Deck tracks every live MLB Statcast leaderboard in one place — exit velocity, barrel rate, hard-hit rate, and sprint speed for hitters, plus four-seam fastball velocity, whiff rate and chase rate for pitchers. Every board uses regular-season data and a published qualifier, and the boards are refreshed nightly.
Play a half-inning in our Statcast-driven sim. Every number on these boards is a real input to a card's rating.
Average exit velocity is the speed of the baseball as it leaves the bat on batted-ball events, measured by Statcast radar at MLB ballparks.
Current leaderBarrel rate (also called barrel percentage or barrel%) is the percentage of a hitter's batted balls that fall into the "barrel" zone — a combination of exit velocity and launch angle that historically produces a minimum .
Current leaderHard-hit rate is the percentage of batted balls with an exit velocity of 95 mph or higher.
Current leaderSprint speed is Statcast's measurement of a player's feet-per-second on their fastest competitive runs of the season, typically drawn from the 2nd-gear portion of a sprint (peak speed, not acceleration).
Current leaderAverage fastball velocity is the mean speed of a pitcher's four-seam fastball across all outings (sinkers, cutters and other fastball types are not included).
Current leaderWhiff rate is the percentage of swings that a pitcher generates without contact (swinging strikes divided by total swings, not total pitches).
Current leaderChase rate (O-Chase%) is the percentage of pitches a pitcher throws OUTSIDE the strike zone that the hitter swings at.
Current leaderSeason-to-date leaderboards reward fast starters for months. The rolling 30-day boards surface who's hot right now, computed from per-event Statcast batted-ball data refreshed nightly.
Every Statcast field is refreshed nightly and stored alongside each player's Legends Deck card. Every leaderboard uses regular-season data and a published minimum. Statcast hitter boards (exit velocity, barrel rate, hard-hit rate): 2.1 plate appearances per team game, MLB's qualified list. Sprint speed: 10 competitive runs. Fastball velocity: 100 four-seam fastballs. Whiff and chase rate: 100 batters faced. Team stat leaders: MLB's 3.1 PA / 1 IP per team game.
