"It's frustrating," Hernandez said. "We've been on a pretty good roll, but sometimes it's going to happen. We just have to go out there tomorrow and play a good game."
The third-inning struggles were a surprising setback for Hernandez, who hadn't given up more than four earned runs in any of his first nine starts of the season. He settled back in and allowed just an infield single over three final frames, but the damage was done as he fell to 4-4 with a 2.86 ERA.
"Obviously he's a great pitcher and has had a great career and has pitched a lot of great ball games here, just tonight was not one of them," said manager Scott Servais.
