• Astros outfielder Adron Chambers was back on the field Monday, one day after being held out of Sunday's intrasquad game because of a strained left hamstring.
"I got a little not, nothing major," Chambers said. "It's from overworking a little bit, kind of running and doing a lot of workouts and stuff like that and I kind of pushed it a little bit and it cramped up on me. They gave me a day to back off on me a little bit."
• After Tuesday's full-squad workout, the Astros will hold a lighter workout on Wednesday before having a night intrasquad game on Thursday. Manager Bo Porter said he wants to give his players a chance to get some rest before Grapefruit League games begin Friday.
