LOUISVILLE, Ky. -- Luke Hancock's career-high 23 points, including two free throws with 46 seconds remaining, helped No. 12 Louisville hold off SMU for a 71-63 victory Sunday in a meeting of Hall of Fame coaches.
Hancock's second consecutive 20-point game helped Rick Pitino's Cardinals (14-3, 3-1 American Athletic Conference) get the final word in his first collegiate matchup against Larry Brown and his Mustangs (11-4, 1-2).
Making his first start despite dealing with a left Achilles issue, Hancock made 8 of 15 from the field - 4 of 9 from 3-point range - to help keep Louisville ahead in a tense game that Montrezl Harrell finally settled with a dunk and a block after Hancock's free throws.
Russ Smith scored 23 points and Harrell added 12 points and 13 rebounds as Louisville bounced back from Thursday's loss to No. 24 Memphis with 47 percent shooting, despite being outrebounded 48-35.
AIR FORCE ACADEMY, Colo. -- JJ O'Brien had 18 points and 11 rebounds as No. 13 San Diego State extended its winning streak to 13 games with a 79-72 victory against Air Force on Sunday.
It is the second-longest winning streak in school history for the Aztecs (14-1, 3-0 Mountain West) and it continues their second-best start ever behind 20-0 in 2010-11.
The Falcons (8-7, 2-2) did not go down easily against the taller, deeper and more physical Aztecs. Air Force led for much of the first half before trailing 31-27 at the break.
San Diego State's rebounding advantage and 3-point shooting proved the difference. The Aztecs held a 39-30 rebounding edge including 17-6 on the offensive end. The Aztecs were 7 of 14 from beyond the arc while the Falcons were 7 of 20.
SEATTLE -- C.J. Wilcox set career highs with seven 3-pointers and 31 points, including 21 in the second half, and Washington ran away from No. 15 Colorado for a 71-54 victory Sunday.
It was Washington's first win over a ranked team since Isaiah Thomas' jumper beat then-No. 16 Arizona in the 2011 Pac-10 Conference tournament championship game. Washington (11-6, 3-1 Pac-12) had lost 12 straight against ranked teams.
Colorado (14-3, 3-1) never recovered after leading scorer Spencer Dinwiddie crumbled to the court late in the first half after his left knee buckled while dribbling on a fast break. Dinwiddie had to be helped to the locker room by teammates and did not return.
The Huskies outscored the Buffaloes 49-29 after Dinwiddie's injury.

Mike Moser scored 24 points to lead the Ducks (13-3, 1-3), who had two chances to tie the game in the final 8 seconds but Johnathan Loyd missed an open jumper and Dominic Artis had a last-ditch layup roll off the rim as time expired.
Oregon opened the season 13-0 but hasn't won since beating Utah in overtime on Jan. 2. The Ducks have since lost to No. 15 Colorado, California and the Cardinal. They have allowed an average of 92.6 points in those games.
