Astros manager Phil Garner said Wednesday he wasn't looking to see any immediate proof that Bagwell was ready.
"Just get the uniform on, come out, take a few ground balls, swing the bat, just like anybody else," Garner said. "I don't, for the first four or five days, look for guys to be going full-bore."
Bagwell missed 115 games last season after surgery on his right shoulder, which has bothered him for four years. He returned late in the season and could bat, but he couldn't throw. He went 1-for-8 with an RBI and a run scored in the World Series.
Garner assumes, but isn't sure, that Bagwell will be able to participate in Friday's drills.
