He gave up two runs and seven hits and saved the A's from having to use more relievers. "That was huge," Oakland manager Bob Melvin said. "The last thing you want to do in a game that you're down 8-0 right away is have to go to multiple guys in the bullpen. Jesse pitched really well."

He's a guy that was as important as he was to us last year, to have to go through a season like this is difficult for him, yet going through some of the issues that he's had to, hopefully he's going to be better for it. We still feel like he has a bright future here."
