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, 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.
The Buffaloes led 30-23 at halftime and were never seriously threatened over the final 20 minutes.
They started the second half with three free throws from Dinwiddie that gave them a double-digit lead. Dinwiddie added a dunk off a steal by Johnson and Andre Roberson's 3-pointer made it 38-23 with 17:50 left, forcing Arizona coach Sean Miller to call his second timeout.
The Wildcats got back in it with consecutive 3s from Lyons and Nick Johnson, and when Grant Jerrett hit a 3-pointer from the top of the circle, the Wildcats had chipped the lead down to 45-39 with 10:43 remaining.
No. 5 Gonzaga 77, Saint Mary's 60 • Gary Bell Jr. scored 20 points and helped fuel a fast start to the second half that helped Gonzaga take a stranglehold on the West Coast Conference race.
