White Sox manager Will Venable said Thursday that Castillo has been moved to the bullpen, Jesse Rogers of ESPN.com reports.

Since being acquired from the Mariners on Aug. 2, Castillo hasn't provided the boost to the rotation that the White Sox had anticipated. Over his seven appearances (six starts) with Chicago, Castillo has labored to a 1-2 record, 7.76 ERA and 1.79 WHIP. In light of his struggles, the veteran right-hander looks like he could be limited to a low-leverage role out of the bullpen the rest of the way. Castillo had been lined up to start Friday versus the Tigers, but rookie David Sandlin is now on track to take over Castillo's spot in the rotation.

Castillo allowed three runs on four hits and three walks while striking out two over 2.2 innings of relief in a no-decision versus the Cardinals on Saturday.

Castillo handled the largest workload for the White Sox in this game, but it amounted to a bullpen game in the end. Castillo has allowed at least three runs in each of his last five appearances, giving up 21 runs (20 earned) over 18 innings in that span. He's at a 5.67 ERA, 1.48 WHIP and 111:43 K:BB through 128.2 innings over 27 games (23 starts) this season. It's not yet clear if he'll start or work out of the bullpen in his next outing, which is projected to be at home versus the Tigers.

Castillo is slated to pitch in bulk relief behind opening pitcher Sean Newcomb during Saturday's game against the Cardinals, James Fegan of the Chicago Sun-Times reports.

The top of the St. Louis lineup typically features two left-handed hitters (Bryan Torres and Alec Burleson) against right-handed pitchers, so the White Sox will have the left-handed Newcomb work the first inning or two in order for Castillo to draw some more favorable matchups when he eventually enters the game. Castillo will be pitching in relief for the first time since being acquired by the White Sox at the trade deadline, with the role change coming after he logged a 7.52 ERA, 1.71 WHIP and 23:8 K:BB in 26.1 innings through his first six starts with the club.

Castillo (4-11) took the loss Thursday against the Astros, allowing six runs on six hits and two walks over four innings. He struck out three.

It was another rough outing for Castillo, who gave up a two-run homer to Jose Altuve in the first inning before the Astros put up a four spot in the third. Castillo's failed to get through five frames in any of his last four starts -- he's given up 17 earned runs on 30 hits in just 15.1 innings during that span. The 33-year-old's ERA is up to 5.57 across 126 innings between the White Sox and Mariners this season. He's tentatively lined up to face the Pirates at home his next time out.

Castillo allowed four runs on eight hits and a walk while striking out a batter over four innings Friday against the Twins. He didn't factor into the decision.

Castillo gave up multiple homers for a third consecutive start, and he's also failed to complete five innings in any of those outings. He's made five starts since joining the White Sox at the trade deadline, and the numbers have been less than impressive -- he owns a 6.45 ERA, 1.66 WHIP and 2.8 HR/9 across 22.1 innings over that stretch. He's tentatively scheduled to make his next start on the road against the Astros.
