SAN DIEGO -- San Diego starting pitcher Clay Hensley left Wednesday's game against the Nationals in the third inning after injuring his right groin.
Hensley broke from the mound to cover first base on a foul ball hit toward the right side by Washington leadoff hitter Felipe Lopez.
Hensley tried to stay in the game, taking a warmup pitch before wincing in pain. He then left the game and was replaced by Doug Brocail.
Hensley allowed a run in the first inning, but he retired the next five hitters he faced before Lopez fouled off a pitch on a 1-2 count. Lopez was the first batter he faced in the inning.
Earlier this season, Hensley had issues with a blister on his right middle finger. But he had pitched well after starting the season 0-3. He was 1-0 with a no-decision and a 2.92 ERA over his last two starts.
