Mike Leake (hamstring) to sit out a turn in Giants’ rotation

Mike Leake will miss a turn in the rotation for the San Francisco Giants because of a strained left hamstring.

Acquired from Cincinnati last week, Leake was scheduled to make his second start for the Giants on Friday. Instead, Ryan Vogelsong will pitch against the Chicago Cubs.

Manager Bruce Bochy said Leake felt the strain in a pregame conditioning session during the recent series at Atlanta. An MRI exam showed no major structural damage. Bochy was unsure if the injury would force Leake — 9-6 with a 3.52 ERA — to miss more than the one start.
