Q&A: Charlie Haeger on the Knuckleball
Charlie Haeger is a practitioner of an increasingly-rare baseball art form. The 27-year-old right-hander is a knuckleball pitcher, meaning he lives and dies with the game’s most unpredictable — and often maddening — delivery. Few have mastered it, but when a knuckleball is thrown correctly and does its butterfly dance toward home plate, it is a thing of beauty. Haeger, who has made 34 big-league appearances, with four teams, was recently signed by the Red Sox and assigned to Double-A Portland.

David Laurila: What is the key to throwing a knuckleball?
Charlie Haeger: First and foremost is being able to take the spin off the ball. Being able to throw a knuckleball isn’t something that a lot of people are able to do, just because you’re not familiar with it growing up. Basically, you have to make the ball rotate as little as possible.
Ideally, for me, would be half a turn, maybe three quarters of a rotation. With that, I can generate the best movement while still being able to command it. You can get away with ones that spin twice, but with anything over that you’re starting to mess with fire.
