There is bat tracking data available on Baseball Savant now! I headed over there to see what data they are tracking and how the Royals look on some new metrics. Before we jump into the Royals however, I just want to note that Giancarlo Stanton is #1 in average bat speed and that he swings fast (above 75mph) 98% of the time, so I believe this data. That is exactly who you would guess is in the top spot. Second in fast-swing percentage is Kyle Schwarber at 73.9%. That is an unbelievably large gap between first and second.
