SAN FRANCISCO -- Few injuries are more persistent than strains of the hamstring, and the one Mike Leake is dealing with will keep him from returning to the rotation Tuesday. Leake will stay on the disabled list and continue to get treatment for the strain in his left leg, with Ryan Vogelsong starting Tuesday and Matt Cain taking his turn Wednesday.
Leake said he can pitch and swing the bat, but running is a concern, and he can only get it up to about 60 percent. Leake is a good hitter, but there are ways to minimize the damage a pitcher can do on the bases. There aren't ways to limit his reactions on ground balls and bunts, and that's the concern. The Giants don't want Leake, a ground ball pitcher, to further injure himself while coming off the mound. The plan is to have him back in the rotation this weekend in Pittsburgh, but Leake said he can't give a firm return date quite yet.

"Each day it gets better," he said. "It's just not ready. You can only go as fast as your body lets you."
Leake said he's officially day to day from now on, and there's a chance the Giants slide him into the rotation before Sunday. That likely depends on how the next couple of days go, and the bullpen was worked hard on Monday when Chris Heston was knocked out in the fifth. There's a chance, Leake said, that he'll be ready to help out in a couple of days.
