Before the start of the season, I wanted to see which pitchers statistically had the best fastballs, curveballs, sliders, cutters, changeups and splitters of the 2010 season.

Here are a look at the top curveballs of the 2010 season. A few notes:

The Pitch Value data was created by Fangraphs.com. I will be using the statistic, wCH, which denotes the runs above average for a particular pitch—in this case a curveball.  

The “wCH” stat benefits starting pitchers and pitchers who throw a certain pitch more often. Because the more often you throw a pitch, the better the chances are of it being successful.

Sometimes, PITCH/FX does not sort pitches into the right category. For example, Brandon Morrow’s splitter was categorized as a fastball.
