Pelfrey will move to the bullpen, effective immediately, Dan Hayes of CSN Chicago reports.

EDGE Analysis

Pelfrey has struggled as a starter this year -- compiling an unsightly 5.09 ERA and 1.48 WHIP through 19 starts (93.1 innings) this season -- prompting the White Sox to shift him to the bullpen as they give youngter Reynaldo Lopez a chance in the rotation. Pelfrey owns an awful 59:47 K:BB this season, so even if he significantly drops his ERA as a reliever, he won't offer much fantasy intrigue.
