When I saw that Arizona Diamondback Willie Bloomquist hit a leadoff HR against the Astros yesterday, the first thing I thought was that it had to be a pitch up and in. Back on April 4th, Bloomquist hit a leadoff HR against the Cubs at Wrigley, and I analyzed how the Diamondback outfielder does well on inside high pitches, particularly fastballs.
Well sure enough, Astros' starter Henry Sosa threw Bloomquist a high inside fastball that he promptly deposited into the left center field stands. Here's his slugging heat map with his HR pitch sequence:
And here's a look at the location of pitches that Bloomquist has taken deep since the beginning of the 2009 season (11 total HRs):
It's a wonder opposing pitchers are still throwing him inside; it's really the only area of the zone that he can do significant damage.
