Mayweather posted a picture on his Twitter account Wednesday morning of a betting slip from the M Resort in Las Vegas that showed he won $37,272.75 on the Bulls, who faced the Atlanta Hawks the previous night.

According to the photo, Mayweather made a halftime bet that the Hawks wouldn't outscore the Bulls by six points or more in the second half. The Bulls made 73.8 percent of their shots in the first half, which ended with a Rose 3-pointer, to go up 72-43. Read more: http://sports.espn.go.com/chicago/nba/news/story?id=6250698
