ARLINGTON -- Third baseman Adrian Beltre will leave Monday morning for Omaha. He is joining Triple-A Round Rock on a medical rehabilitation assignment in the hopes of being activated by the Rangers on Thursday. Beltre said he is ready to be activated now, but that's not going to be the case. "I'm good enough to play," Beltre said Sunday afternoon. "I'd rather not go, but that's the orders. I'm going to do whatever they ask me to do. But I don't like rehab assignments."
He hasn't been on one since 2001, when he missed the first six weeks of the season with the Dodgers because of a strained abdominal muscle. He did not go on a rehab assignment in 2009 with the Mariners, after he missed more than a month after shoulder surgery. But Beltre has been sidelined since July 23 with a strained left hamstring, he has already had one setback that cost him an extra three weeks and the Rangers want to make sure he's ready to go. Manager Ron Washington said Beltre has to learn to "manage" his hamstring. Beltre, who missed three weeks with a strained hamstring in 2000, said he has learned to do that. "I manage it every year," Beltre said. "It's just this year I've had a problem. It might be the heat. I pulled the hamstring in 2000, and every year they get sore. I know how to deal with it."
