Hoerner was removed from Sunday's game against the Giants in the top of the sixth inning due to right triceps tightness, Tony Andracki of Marquee Sports Network reports.
Hoerner went 2-for-2 with a double to begin Sunday's matchup, but he was replaced defensively to begin the sixth inning. It's not yet clear whether the 25-year-old will be available for Monday's series opener against the Mets.
