White Sox manager Will Venable said Sunday that Fedde will be moved to the bullpen following the team's acquisition of right-hander Luis Castillo, James Fegan of SoxMachine.com reports.
Rather than expanding the rotation to six or demoting struggling rookie Noah Schultz to the minors, the White Sox will instead shift Fedde to a long relief role. Fedde had been part of the rotation all season but 10 of his 22 appearances have come as a bulk reliever, so it likely won't be a big adjustment. The veteran righty has gone 6-6 with a 4.13 ERA, 1.37 WHIP and 74:36 K:BB in 102.1 innings this season.
