Tigers option RP Guido Knudson to make room for Ferrell, Machado

Following Thursday's blowout loss, the Tigers optioned reliever Guido Knudson to Triple-A Toledo. 

Knudson has not had a good start to his young career, as he owns a 18.00 ERA through four relief appearances since his first call-up to the big leagues back on Aug. 22. He has been scored upon in all four of his outings.

In related moves, the Tigers will recall pitcher Jeff Ferrell and infielder Dixon Machado from Toledo prior to Friday's game.
