It hasn't been discovered exactly what happened, but apparently Aceves was not pleased with manager Bobby Valentine after Friday's game against the Kansas City Royals. The suspension began on Saturday night.
Aceves has been just another disappointment in a topsy-turby 2012 season for Boston, posting a 4.60 ERA in 58 games out of the bullpen. On the bright side, he does lead the team with 25 saves.
In his last appearance, Aceves was touched up in a big way against the Los Angeles Angels, allowing five runs in just 1+ inning during the Red Sox 14-13 extra-inning loss on Thursday night.
For now, it's assumed by most that former closer Andrew Bailey will take over the ninth inning duties now that's he's healthy.
