(CBS) Chicago area native and Hornets big man Frank Kaminsky didn’t hide his disdain for the Cubs upon entering the United Center on Monday night for a preseason contest against the Bulls.

A longtime White Sox fan and Benet Academy product, Kaminsky donned a Cubs jersey with “Bartman” on the back, a reference, of course, to Steve Bartman, the fan who interfered with Cubs outfielder Moises Alou on a key play in Game 6 of the National League Championship Series in 2003. The Cubs would go on to lose that game and series.

Remarkably, Kaminsky wore the custom-made jersey to a rooftop across from Wrigley Field on Sunday to watch Game 2 of the Cubs-Dodgers series, he told CSN Chicago’s Chuck Garfien.

“There is a sense of jealousy,” Kaminsky told Garfien. “I’m a White Sox fan. I don’t want to see them do well.”
