White Sox strength coach was a KISS-themed wrestler

Before he was the White Sox strength and conditioning coach, Dale Torborg was a professional wrestler using a KISS gimmick for WCW:
When his days of black-and-white face paint and laying the smack down on jabronis were over, Torborg opted for a career in baseball (his dad was an MLB-er). Torborg has been with the White Sox since '04 and helped them to a World Series title and multiple professional wrestling cameos.

His influence on the Sox obviously extends to the weight room, where players compete for replica title belts Torborg commissioned to motivate the team.
