Examining Wade LeBlanc’s Change-Up

Since replacing injured pitcher Chris Young in the starting rotation, Wade LeBlanc has been lights out for the San Diego Padres. In 23 innings he has a 1.16 ERA, a 2.15 FIP, and a 3.61 xFIP. LeBlanc is unlikely to sustain such excellence for the entire season, but based on his performance thus far, there is no reason to think he cannot be a league average pitcher going forward.
LeBlanc’s best pitch is his change-up. He throws it 25 percent of the time, and according to Fangraphs, it has been 5.73 runs above average per 100 pitches so far in 2010. LeBlanc throws his change-up at 77 mph, 10 mph slower than his fastball.
Because his change-up is so solid, I wanted to see how it compared to some of the major league’s best change-ups according to pitch f/x.
I sorted by the 2009 leaders in change-up runs above average (total, not per-100), and selected the top three lefties for comparison. The players with the best lefty change-ups in 2009 were: CC Sabathia, Cole Hamels, and Mark Buehrle.
The following table notes how often each pitcher threw his change-up, as well as some speed statistics:

The speed difference between LeBlanc’s fastball and change-up is a bit less than Sabathia, but compares favorably with Hamels and Buehrle.
This table highlights each pitcher’s horizontal and vertical movement on his change-up;

Sabathia gets the most horizontal movement on his change-up, but it stays up a bit more than the others’. Buehrle’s change-up has by far the most sink. The movement on LeBlanc’s change-up is pretty similar to Hamels’.
Finally, lets take a look at the pitch flight charts. The charts were created using data from Brooks Baseball, and are pitch flights for each pitcher’s most recent start:

There are slight differences between each of the pitcher’s change-ups, but frankly, they are pretty similar. For LeBlanc, this is a good thing. His change-up is pretty comparable from a “stuff” perspective to Sabathia, Hamels, and Buehrle, three of the top change-up pitchers in baseball. LeBlanc is unlikely to ever be as good as those three because there is a lot more to pitching than just having a good change-up, but it is certainly a start.
