Diamondbacks reliever David Hernandez has had a rough go of it since returning from Tommy John surgery on June 7. In particular, the right-hander has really struggled over the his last three appearances, and the hard times continued on Tuesday.

Hernandez suffered his first loss of the season in the 6-4 defeat to the Dodgers. He entered the game in the top of the 10th inning with the scored 4-4. But he allowed three runs to score in the 10th, including a go-ahead home run to Howie Kendrick. 

Hernandez has now given up five runs over his last three outings, and owns a 7.50 ERA this season.

"For just so long, you grow accustomed to pitching and feeling fine, like nothing happened," Hernandez said, per MLB.com. "But I know it's going to take time. But up here there's no time, you've got to get the outs before obviously they score any runs."
