The Best Pitches of 2014 (By Whiffs)
There are many different ways to describe the quality of a pitch. We have movement numbers on this site. There are ground-ball rates. There are whiff rates. There are metrics that use a combination of ground-ball and whiff rates. And metrics that use balls in play. There’s a whole spectrum from process to results, and you can focus on any one part of that spectrum if you like.
But there’s something that’s so appealing about the whiff. It’s a result, but it’s an undeniable one. There is no human being trying to decide if the ball went straight or if it went up in the air or if the ball went down. It’s just: did the batter swing and miss? So, as a result, it seems unassailable.
Of course, there are some decisions you still have to make if you want to judge pitches by whiff rates. How many of the pitch does the pitcher have to have thrown to be considered? Gonzalez Germen had a higher whiff rate on his changeup (30.7%) this year than Cole Hamels (23.7%). Cole Hamels threw seven times as many changeups (708 to 101).
So, in judging this year’s best pitches, let’s declare a top pitch among starters and a top pitch among relievers. That’s only fair, considering the difference in number of pitches thrown between the two. It’s way harder to get people to keep missing a pitch they’ve seen seven times as often. And, in order to avoid avoiding R.A. Dickey the R. A. Dickey Knuckler award, we’ll leave knucklers off the list, and include knuckle curves in among the curves.
