Barry Zito pitched around a rain delay to hold the Tigers scoreless for six innings on Saturday. Even though Zito was working on three days' rest tonight, the Giants let him stay in following a 2 1/2-hour delay in the third. But what's the risk? He only has another $55 million left on his contract. Hopefully, Zito will bounce back well from the irregular outing. He has a 3.81 ERA in his five starts this season.
