Berkman is used to being an everyday player, and manager Ron Washington said a limited role might be tough on him.
"It probably would, but he's got experience," Washington said. "He'll figure it out, and he'll go up there and get us a hit."
"I have 10,000 at-bats in my career," Berkman said. "I have a lot of experience. If you can't hit by now, you can't hit."
Jurickson Profar has filled in as a part-time designated hitter with Berkman out, and Washington has rotated other players through the position. Berkman was hitting .254 with six home runs and 34 RBIs in 68 games before going on the disabled list.
"The team is playing great," Berkman said. "The last thing you want to do is come in and be a detriment to the mix."
