Hi everybody. I'm Josh Kalk the harbdalltimes writer and blogger. In the off season I wrote this article on Tim Lincecum where I noted that while he didn't throw any sliders in 2007 he had thrown that pitch in college and was rumored to be tinkering with it. Even though the 2008 data still has a lot of issues, Lincecum is definitely throwing a slider this year. Here is a plot of his movement on his pitches with the pitch identification from MLBAM:
The splitters should be change ups and the cutter really is a slider. Anyway, last year Lincecum mostly threw his curve to right handers and his change to left handers. This year it looks like that has continued but he is throwing his slider to both. It appears he is still throwing about 2/3 fastballs but now he is using his curve ball much less.
Sadly I haven't gotten a chance to watch him pitch this year so I am curious if you guys who have seen him all year have noticed the slider and what you guys think? As I noted in my article while Lincecum's curve got a lot of press I was very impressed with his change. Where do you think his slider fits in?
