Bryce Harper exited Thursday's game after injuring his left groin on a diving catch against the Arizona Diamondbacks.

Dusty Baker said Harper was removed for precautionary reasons and is day-to-day.

Harper said he felt the injury after making a headfirst diving catch near the right-field line in the third inning. He left the game after striking out in the sixth.

"Got it a little bit on the fly ball. That dive. I gotta stop diving, trying to catch fly balls too much," Harper said. "Just felt it a little bit. Little tight."
