Players’ View: Are Two-Seamers and Sinkers the Same Pitch?
The terms “two-seamer” and “sinker” are synonymous. Or are they? It depends on who you ask — and even then, there’s ambiguity in the answer. If an exercise in semantics is what you’re after, pursuing this subject with a cross section of pitchers and pitching coaches might be a good place to start.
I learned that over the past week. Prompted in part by Alex Stumpf’s article, The Death of the Sinker , I solicited the opinions of 12 — four from each team — members of the Boston Red Sox, Seattle Mariners, and Texas Rangers. Here’s what they had to say.

Brian Bannister, Red Sox assistant pitching coach: “It’s basically the same grip, but for some power pitchers, it’s kind of a variation on the four-seamer with a little more arm-side movement; it’s really a derivative of their four-seamer. For other guys, it’s their bread-and-butter pitch where they’re trying to get the hitter to hit the top half of the ball. For some guys it misses more bats, and for other guys the purpose is to get ground balls.
“It depends on how your arm works and how your hand works through the ball. For some, it’s really more of a two-plane fastball. For others, it really goes down. Guys like Jake Arrieta, Noah Syndergaard, and Michael Fulmer throw two-seamers that end up above barrel, whereas with your Trevor Cahills and Dallas Keuchels, it ends up below barrel.”
