Bat Speed and Swing-Quality Leaderboard
Statcast bat-tracking leaders by bat speed, squared-up rate, blast rate, hard-swing rate and swing run value. These are leading indicators of power: they move before batting average and slugging catch up, so they flag a hitter's change while he's still cheap.
Bat Speed & Swing Quality
Statcast bat tracking — bat speed, squared-up%, blast% and swing run value. These are power leading indicators: a hitter adding bat speed and blasts before the results follow is a swing-quality buy-low; one losing bat speed is an early sell.
Blast = a fast, well-squared swing (the highest-damage contact). Squared-up = how much of possible exit velo the swing captured. Run value is total swing-decision + contact value. League avg bat speed ~71 mph; blast .
