Giants manager Gabe Kapler told reporters after Tuesday's game against the Marlins that Wood (hamstring) will likely be placed on the 15-day injured list, Evan Webeck of The San Jose Mercury News reports.
Wood left his start in the third inning after suffering a left hamstring strain while fielding a bunt and making an awkward throw to first. The left-hander appears all but certain to log an IL stint, and the Giants will consequently need to add a rotation arm for the next couple of weeks at the very least.
