The sinkerball is a great pitch to have in an arsenal for a pitcher. Because of its downward movement a sinkerball induces a lot of ground balls, which, as we all know, are a pitcher's best friend.
There aren't as many guys in baseball that throw this pitch that you might think, but of the ones who do, they throw it often.
Ultimately, however, the sinker does not lend itself to amassing the "sexy stats" (i.e. strikeouts), and thus sometimes sinkerball pitchers can be undervalued. A strikeout is great, but nothing is better than getting ground balls on a consistent basis—especially when there are men on base. Ground balls not only lead to fewer hits, but they also lead to more efficient innings and thus the ability to stay in the game longer.
*A note to keep in mind as you continue reading: This list is meant to discuss the best sinkerball pitchers in 2011 thus far. It is not a list comprised of the best sinkers of all time. Thus, stats listed will always be from the 2011 season only.
Before we begin with the best sinkerball pitchers, in no particular order, let's look at a few players who did not make the list but were close.
