CHICAGO (CBS) – The White Sox granted reliever Brian Bruney his unconditional release Monday after the right-handed reliever cleared waivers and rejected an assignment to Triple-A Charlotte.

Bruney was designated for assignment Aug. 6 when the team called up pitcher Zach Stewart, who they acquired from the Blue Jays in a trade last month. Bruney had been thrown out of a game Aug. 3 for arguing a call with first base umpire Marvin Hudson. Replays showed the call was correct and both manager Ozzie Guillen and pitching coach Don Cooper expressed displeasure with Bruney for being ejected.

The 29-year-old right hander signed as a free agent with the White Sox last December and was 1-0 with a 6.86 ERA in 23 relief appearances this season.
