Poll: Home Plate Collisions



Reader Feedback: Analyze This!

This past week we received an email from Eli asking us to take a look at Buster Posey vs. the fastball in 2011... 

I was wondering if you guys could maybe run some analytics on Buster Posey's struggle to hit fastballs this year. Being a Giants fan and watching most of his at bats, it seems like he is really struggling to hit fastballs during the beginning of his 2011 season.

It could be me just overreacting to his start, but it might be interesting to take a look at.



We took the time and posted "Buster Posey vs. Fastballs". Please feel free to send us a note if there is analysis that you would like to see!


Buster Posey vs. Fastballs

A reader requested we take a look at how Buster Posey has fared versus fastballs this season.  Contrary to his concern, Posey has actually done well against the pitch in 2011.  He's hit .316 and slugged .456 compared to .284 and .483 prior to this year. 

One reason his average is up on fastballs is because he's hit 9 line drives off them this season, and all 9 have fallen for hits.  However, none of them have been for extra bases, which could be why his SLG% is down slightly.

From the above graphic, you can see that his power is a bit more spread out against fastballs this season.  Last year, he hit fastballs up and out over the zone extremely well.  In fact, on fastballs in the upper portion of the pitching zone, Posey slugged .565 last season with three doubles, one triple, and four home runs.

Posey has actually had trouble versus off-speed pitches in 2011.  His average is down from .313 in 2010 to .222 so far this year.  Against changeups in particular, Posey has really struggled; his average is down 177 points. 

It's a little early to get hung up on pitch type results, but as far as fastballs are concerned, Posey has hit about as well as he did in 2010.
