FanGraphs now has a Statcast Bat Tracking section available on both the player pages and the leaderboards.

The following stats are included, with basic definitions from the MLB Statcast glossary. Please refer to the linked Statcast glossary page for more in-depth descriptions of the statistics.

Bat Speed (BatSpd): “How fast the sweet spot of the bat is moving, in mph, at the point of contact with the ball (or where the ball and bat would have met, in case of a swing-and-miss).” (MLB glossary link)

Swing Length (SwgLng): “Swing length is a metric intended to identify if a batter has a short or long swing. It is calculated in terms of feet the bat traveled during the swing.” (MLB glossary link)

Fast-Swing Rate (FastSw%): “Statcast defines a ‘fast swing’ as one that reaches a swing speed of 75 mph. A player’s ‘fast-swing rate’ is simply showing the percentage of all of his swings that did reach 75 mph. In the first month of 2024, 23% of all swings qualified as a ‘fast swing.'” (MLB glossary link)

Squared-Up Contact Rate (SqUpCon%) and Squared-Up Swing Rate (SqUpSw%): “A swing’s squared-up rate tells us how much of the highest possible exit velocity available (based on the physics related to the swing speed and pitch speed) a batter was able to obtain – it is, at its simplest, how much exit velocity did you get as a share of how much exit velocity was possible based on your swing speed and the speed of the pitch.” (MLB glossary link)

Blast Contact Rate (BlastCon%) and Blast Swing Rate (BlastSw%): “A blast, in Statcast terms, is when a batter squares up a ball and does so with a high bat speed.” (MLB glossary link)

Swing Path (Tilt): “Swing path is a metric that tells you the shape of a hitter’s swing on the way toward contact. The tilt of the swing is defined as the vertical angle formed by the bat path compared to the ground.” (MLB glossary link)

Attack Angle (AtkAng): “Attack angle measures the vertical direction that the sweet spot of the bat is traveling at the moment it hits the baseball.” (MLB glossary link)

Attack Direction (AtkDir): “Attack direction measures the horizontal direction that the sweet spot of the bat is moving at the point of contact with the baseball (or the point the bat and ball cross paths on a swing-and-miss).” (MLB glossary link)

Ideal Attack Angle Rate (IdealAtkAng%): “A hitter’s ideal attack angle rate is the percentage of his competitive swings that fall within the 5-20 degree attack angle range.” (MLB glossary link)
