After giving up seven runs in less than two innings Sunday, Mike Fiers may have thrown his last pitch for the foreseeable future in the Milwaukee Brewers' starting rotation.

Fiers' dreadful start was the difference in a 7-5 loss the Brewers could have won if not for the early and deep hole their pitcher dug for them.

After the game, Brewers manager Ron Roenicke indicated a change would be made at Fiers' spot in the rotation, perhaps with a call-up. While starting pitching is a problem at Class AAA Nashville, the Brewers' second-round pick from 2010, Jim Nelson, has pitched well at Class AA Huntsville.

"We'll discuss that (Monday) and figure out what we'll do there," Roenicke said. "There are a few options."

Fiers, who put the Brewers in immediate arrears by giving up a first-inning three-run homer to Domonic Brown, was candid about his struggles.

"I just feel like it was bad pitching on my part," he said. "I let them get up early. That's tough on a team when starting pitching doesn't get it done in the first inning. It doesn't give a team a chance. Just bad pitching.

"We battled back. We definitely could have won this game, and I made it tough for us. It makes it even worse on me to think...I don't even know the word...a gutless performance for not bearing down and getting the outs I needed to get."

Asked about possibly losing his spot in the rotation, Fiers said, "I'm not making a good case for myself with a performance like this. It's embarrassing to me."

He said his biggest mistake was not following the scouting report on the red-hot Brown, who crushed a 3-1 pitch from Fiers out of the park for his eighth home run in nine games.

Fiers, who was 9-10 with a 3.74 ERA last season as a rookie, is now 1-4 with a 7.25 ERA.

"It's life and conviction with his pitches," Roenicke said. "I talk about confidence. Last year when he came up, he was confident. He knew he could throw the fastball past hitters."
