Thome left the Phillies’ 10-4 win in Tuesday’s series opener after the fifth inning with a left thumb injury. Team officials said he tweaked the thumb while fielding a groundball from Tyler Walker. He had been 2-for-3 with an RBI triple.
Although Thome has missed just two games this season, his thumb has bothered him in recent weeks. He sat out a 6-4 loss to Arizona on May 1 after receiving a cortisone shot the previous night.
The Giants might also be missing their regular first baseman.
J.T. Snow left after the fifth inning as a precaution after hitting the back of his head on the ground. He was chasing a foul ball by Marlon Byrd in the fourth, lunged over the dugout railing but didn’t make the play. He fell hard as he came back and struck his head on the ground. The Giants said they did not believe Snow had a concussion.
Kevin Millwood, who threw a no-hitter against the Giants last season, pitched 6 2-3 strong innings Tuesday, and Marlon Byrd had a three-run triple to help Philadelphia improve to 4-0 on its 10-game road trip.
The Phillies’ 10 runs were the most they’ve scored since beating Florida 14-0 on Sept. 16. Their 15 hits were two off their season high.
Barry Bonds went 1-for-3 with an intentional walk for the Giants. His double off Millwood in the second ended an 0-for-15 slump.
Bonds said before the game he was “feeling better” after a sinus infection forced him to miss three straight starts last week.
