ARLINGTON -- Rangers third baseman Adrian Beltre, on the 15-day disabled list with a strained left hamstring, did some light running on Saturday just before joining Triple-A Round Rock to begin his rehab assignment on Monday.
"It's coming good. It's not 100 percent, but it's manageable," Rangers manager Ron Washington said. "You never are 100 percent with hamstrings. Hamstrings get well when you no longer have to use it, and you can just strengthen, strengthen, strengthen."
There is no timetable for his return, but Washington has insisted that a player as experienced as Beltre can come back into the lineup on short notice without too much adjustment time.
"We'll see how the first day goes, and then we'll see from there," Washington said.
Beltre is batting .276 with a .505 slugging percentage in 388 at-bats this season. He played in each of the team's first 100 games, starting 99 of them.
Washington said when Beltre comes back, the best thing he can do to avoid re-injuring the hamstring is to not exert himself too much on the basepaths.
"Ball is hit in the gap, instead of you forcing it to home plate, you stop at third," Washington said. "Normal base hit that maybe you would score on, if you can't score, you stop at third base. That's the way you manage it. Balls he normally would do more on, you've got to recognize and not do more on it. That's all you can do."
Beltre, who injured the hamstring on July 23, suffered a setback on Aug. 7 that caused him to restart his rehab after giving his hamstring more rest. Washington thinks the injury may show Beltre how fragile his hamstring is.
"He understands [he has to manage it] because he hurt it again," Washington said. "If he wouldn't have hurt it again, we might not have had that problem. Since he hurt it and he knows how important he is, he's got to manage it.
"We are definitely going to have to help him monitor it, because Beltre doesn't know the meaning of monitor."
