Phillies pitcher Cole Hamels left Monday's start with back pain, according to the Philadelphia Enquirer.
Hamels experienced some discomfort during his pre-game bullpen session, which led to his early exit. Hamels only threw 87 pitches during a 1-1 duel with Stephen Strasburg. There's no indication the injury will prevent him from making his next start.
Hamels has a 3.50 ERA in 193 innings.
