When Oakland A's left-hander Brian Fuentes lost his closer role to Ryan Cook last month, he went from working almost every day to almost not at all.
Some of that was because of an ankle injury that cost him more than week, but manager Bob Melvin also couldn't quite find roles to put Fuentes in with Cook as closer and with so many other left-handers performing well in the bullpen.
So on Tuesday, when the A's needed to make a move to get Bartolo Colon off the disabled list to start against Boston, they designated Fuentes for assignment before the team's 3-2 win over the Red Sox.
Fuentes, 36, said that he understood the situation and the fact that he hadn't been performing consistently well.
"They're developing guys, they can't wait for me forever," the four-time All-Star said. "It's a crummy situation, but I go away feeling good about it. ... In this game, you learn it's a revolving door. Very few guys stay in one place for a long time."
Although the A's have 10 days in which to trade Fuentes, there is not thought to be a strong market for him. He is owed about $2.5 million the remainder of the season, and there is a $500,000 buyout on his deal for next year.
