Why Would You Ever Throw Derek Jeter Anything But A Fastball?
What’s an “average” fastball velocity? This year, it’s 91.9 mph. Last year, it was 92.0 mph. In 2012, it was 91.8 mph. We could go back further, but since that’s all pretty consistent and this isn’t really going to be about how hard pitchers throw anyway, three years is fine. We can say that 92 mph is pretty much the average fastball speed in Major League Baseball.
So with that knowledge in mind, here’s what I wanted to know: what hitters have to deal with the most heat that’s at average and above velocities? And how do they handle it? Fortunately, we have Baseball Savant, so we can look at this pretty easily. With a minimum of 500 fastballs seen — for reference, Matt Carpenter and Brian Dozier have each seen over 1,200 total pitches, so 500 pitches would be fewer than half of what an everyday player would have received — there’s only three hitters who have seen at least 35 percent of pitches coming in at 92 or higher:
