Barry Zito was stellar in Saturday's victory over the Diamondbacks, allowing only one run on six hits over 6 2/3 innings. He struck out four while walking just one on the evening. The only damage against him came on a solo homer by Justin Upton in the fourth inning. Sure, he hasn't quite lived up to his massive free agent contract, but Zito has been a fairly serviceable starter for the Giants this season, posting a 12-8 record, 4.21 ERA and 99/65 K/BB ratio over 166 2/3 innings. He'll look to replicate this fine outing when he takes on the Rockies at home on Thursday.
