"I don't expect him to play tomorrow. He just came here and said his hamstring is very sore," Guillen said after Thursday's 7-5 victory over the Rangers. "I don't blame him from all the running he was doing yesterday. I was sore, and I was on the bench. But he's taking it day-to-day, but he's not playing tomorrow. He should be fine the next day."
Quentin had shown signs Wednesday night of breaking out of his season-long slump, with a three-run home run, a double and two runs scored. But Guillen was most impressed by Quentin taking a second-inning walk and going the opposite way with both of his hits.
"If Carlos stays where he is right now, this kid is going to put up numbers," said Guillen of Quentin, who is hitting .183 with four home runs and 17 RBIs. "The best thing he did was not swing at every pitch.
"He hit the ball to right-center, which is what he does the best. Just stay in the middle to right field and don't swing at the pitch he shouldn't swing. He's a better hitter and a very different hitter."
Juan Pierre moved from designated hitter to left field in Quentin's absence. Andruw Jones moved from left field to right, and Mark Kotsay entered the game as the designated hitter, batting seventh.
