Adbert Alzolay’s Curveball Spin Rate Among Highest in MLB
Adbert Alzolay has only made one MLB appearance, but his curveball is already among the most impressive in the game. According to early data, the average spin rate on his breaking ball is greater than over 90% of MLB righties.
Just look at Alzolay’s curveball spin rate RPM distribution (red) shifted all the way to the right of the distribution for the rest of the league (blue). That’s insane, folks.
