Moore has a left meniscus injury that will be "treated conservatively," though he could return to play this season.
Moore exited a Double-A game Friday after hurting his left leg, and the Angels announced Wednesday that he suffered a meniscus injury. The organization indicated that the 21-year-old will get conservative treatment before trying to ramp up his baseball activity but didn't rule him out from returning in the regular season. That's a bit surprising considering that the Double-A campaign ends on Sept. 15.
