Sebastian Mack scored 19 points and UCLA rallied after blowing a 14-point, second-half lead to beat Colorado 64-60 on Thursday night for its sixth consecutive victory. The Bruins (14-11, 9-5 Pac-12) took over sole possession of third place, passing idle Oregon with their eighth win in nine games since starting the season 6-10. “Obviously this team has grown up a lot,” Bruins coach Mick Cronin said.
