Houston Astros outfielder George Springer exited Monday's game against the Philadelphia Phillies due to left quad discomfort, according to Jerry Crasnick of ESPN.com.
He was 0-for-2 with a strikeout before exiting in the third inning.
Springer has been relatively durable lately, only missing a handful of games this year after playing all 162 last season. He entered Monday with a .311 batting average, 27 home runs and a league-leading 82 runs scored.
The 27-year-old also earned his first All-Star selection this year in his fourth season in the majors.
