Pence's Impatience Costing Him with Giants
Hunter Pence, by all accounts, is an enthusiastic fellow. Pence runs out routine grounders like he's squaring off against Usain Bolt. He's known to crash into walls and even the occasional sliding glass window. But Pence has been a little too gung-ho in the batter's box since being traded from the Phillies to the Giants on July 31. And it's costing him and his new club.
Pence wasn't exactly a strike-zone guru with Philly, but both his 8.4% walk rate and 19.3% strikeout rate were right around the MLB average in 2012. With San Francisco, however, Pence has drawn a walk just 4.8% of the time and he has punched out 26.2%.
With the Phillies, Pence swung at plenty of high pitches out of the zone. Despite that, his overall 29.2% chase rate was close to the MLB average (28.5%):

Since changing coasts, Pence's strike zone has practically stretched from Philly to San Fran:

Pence has chased 37% of pitches thrown out of the zone in San Francisco. He's 1-for-24 on those outside pitches, striking out 16 times in the process. While Pence's pep endears him to teammates, he's got to tone it down at home plate to help the Giants' playoff prospects.
