Oakland Athletics manager Bob Melvin has named left-hander Brian Fuentes as his closer on Saturday.
"We're closing with Fuentes for now," Melvin said after Saturday's game. "I didn't announce that, but that's the position that we're in right now. We're giving (Grant Balfour) a little bit of a break, and we're going to close with Fuentes for the foreseeable future."
Balfour was named the closer entering the season. He has converted seven of his nine save chances, but has a 4.41 ERA in 16 1/3 innings.
Fuentes, who saved Saturday's 3-1 victory over Detroit, has two saves in 14 innings this season with a 3.86 ERA. Fuentes, who has previously been the closer for Colorado and the Los Angeles Angles, earned this 200th career save on May 2.
"That's what I want to do," Fuentes said. "So not doing that was tough. But at the same time I understand the dynamics of the bullpen. You're going to go with the guy whose best suited for the job at the time, and at the beginning of the season, that wasn't me. I understand."
