"It's hard to tell right now," trainer Stan Conte said. "He was walking normally when he left here. We'll take a look at him before the day game tomorrow and see how he recovers. With pulls, it's kind of hard to tell until the next day. We'll know a lot more tomorrow. I'm not thinking DL right now."
Ramirez, who is not speaking with reporters, told Conte he had trouble getting loose before the game on the outside of the right hamstring, but Conte said there was no pre-existing injury.
"He didn't feel it pop, so hopefully he's OK," said manager Joe Torre.
Ramirez had singled Andre Ethier to third base with two outs and James Loney followed with a single that scored Ethier. Ramirez rounded second, stopped, slowly spun around and headed back to second base before realizing there would be a play and made a late slide.
He originally was called out by umpire Ron Kulpa, but his right foot landed on the glove of Giants shortstop Edgar Renteria, kicking the ball loose. He came up limping and Matt Kemp was sent in as a pinch-runner. Kemp was out of the lineup for a third consecutive game.
The 38-year-old Ramirez is hitting .460 since June 13. He already has spent one stint on the disabled list this year with strained right calf muscle.
