Fulmer was optioned to Triple-A Charlotte after Tuesday's game.
The White Sox needed to clear a roster spot in order to call up Wednesday's scheduled starter, Anthony Ranaudo, so Fulmer will head back to the minors. He gave up 11 runs (including two home runs) in 11.2 innings of relief in his first taste of the majors. Fulmer will be stretched out at Triple-A, and has a chance to come back to the big league club as a starter in September, according to MLB.com's Scott Merkin. Of course, his struggles this time around as a reliever -- a role many thought he would excel in -- and his 4.76 ERA and 1.53 WHIP in 87 innings as a starter at Double-A this season make him an unappealing add in single-season formats, even if he gets a chance to make some starts for the White Sox in September.
