Statcast, the high‑speed camera and radar network installed in every major league ballpark, captures a staggering amount of data on every play. By translating raw motion into measurable numbers, it gives teams and analysts a window into the physics of hitting, pitching, fielding and running that goes far beyond traditional stats.
Hard‑Hit Balls and Launch Angles
A batted ball is classified as a hard‑hit when its exit velocity reaches 95 mph or higher. When a ball leaves the bat at an angle between eight and 32 degrees, it typically follows a trajectory that maximizes distance and run potential, creating what analysts call an optimal launch window.
Batting Expected Metrics
Expected metrics such as xBA (expected batting average) estimate the probability that a given batted ball will become a hit, using exit velocity, launch angle and sprint speed as inputs. Another useful figure, EV50, averages the hardest half of a batter’s contacts — or conversely the softest half of a pitcher’s allowed hits — to gauge consistency. Adjusted EV takes the maximum of 88 mph and the actual exit velocity for each event, smoothing out low‑velocity outliers.
Pitching Analytics
Pitchers are evaluated through a suite of motion‑based stats. Speed is reported in miles per hour, while movement is measured in inches relative to a league‑average baseline. The spin that drives that movement is called Active Spin and is expressed in revolutions per minute. Combining these elements, xERA translates expected performance into a familiar ERA scale, giving a clearer picture of a pitcher’s true effectiveness.
Defensive Reach and Arm Strength
Fielding metrics start with catcher pop time, the interval from glove‑to‑release when attempting a steal or pickoff. Throw speed records how hard a fielder launches the ball, and range tracks how far a runner strays from the bag before a pitcher’s first movement. Jump captures reaction time and route efficiency in the outfield, while Outs Above Average (OAA) quantifies defensive savings in runs. Catch probability, expressed as a percentage, predicts the likelihood that an outfielder will secure a given ball.
Speed on the Bases
Sprint Speed measures a player’s peak one‑second velocity in feet per second, and any run completed at 30 ft/sec or faster is labeled a Bolt. These numbers highlight the league’s fastest athletes and influence decisions on aggressive base running.
