BOULDER, Colo. -- Spencer Dinwiddie scored 21 points and freshman Xavier Johnson added a season-high 19 as Colorado avenged a bitter overtime loss at Arizona with a 71-58 rout of the ninth-ranked Wildcats on Thursday night.
Unlike last month's game in Tucson, there was no controversy at the end of regulation -- just Colorado fans storming the court in celebration.
On Jan. 3, the Buffaloes' apparent game-winning 3-pointer was waved off at the end of regulation even though replays showed the shot was taken in time.
Dinwiddie scored 19 points in the second half Thursday, leading the Buffaloes (17-7, 7-5 Pac-12) to their 11th win in 12 home games and sending the Wildcats (20-4, 8-4) to their second straight loss.
Johnson also had nine rebounds.
Solomon Hill led Arizona with 12 points and Mark Lyons had 11.
