Chicago White Sox: The White Sox recalled right-hander Jon Rauch from Triple-A Charlotte on Sunday.
In his last stint with Chicago, Rauch drew criticism from general manager Kenny Williams and several White Sox teammates after he left the clubhouse before the end of a 5-1 loss to Anaheim on May 29.
The 6-foot-11 Rauch, who arrived at Olympic Stadium during the game, was sent back to Charlotte after his dismal start against the Angels when he gave up five runs and 10 hits in 3 2/3 innings.
Williams went down to the clubhouse in the ninth inning in an attempt to talk to Rauch about his performance, but Rauch had already left.
Rauch is among five pitchers who have combined to go 0-8 as Chicago's No. 5 starter, including Arnie Munoz, who was sent back to Charlotte immediately after making the worst debut by a starter in the majors in over eight years Saturday.
Munoz, who turns 22 on Monday, was recalled from Double-A Birmingham on Friday. He allowed 11 runs and 10 hits in three innings in a 17-14 loss to the Expos.
It was the worst debut since April 7, 1996, when St. Louis' Mike Busby allowed 13 runs -- eight earned -- and nine hits in four innings of a 13-3 loss in Atlanta.
