Askia Booker scored a career-high 27 points, including 11 in the last 4:40, and No. 20 Colorado rallied in the second half to hand No. 10 Oregon its first loss of the season, 100-91, on Sunday.
Spencer Dinwiddie added 23 points and Xavier Johnson and Josh Scott had 15 points apiece for Colorado (13-2, 2-0 Pac-12), which is off to its best start since the 1968-69 team began the season 13-2.
Mike Moser had 24 points to lead Oregon (13-1, 1-1). Joseph Young and Damyean Dotson each had 16 points.
NO. 4 WISCONSIN 75, NO. 22 IOWA 71: Ben Brust scored 19 points, and Wisconsin remained unbeaten with a victory over Iowa.
Wisconsin (15-0, 2-0 Big Ten) matched the best start in school history, tying the 1911-12 and 1913-14 teams.
The game was physical at times, drawing loud protests from both coaches. But Iowa coach Fran McCaffery boiled over after a foul was called on Gabriel Olaseni that sent Nigel Hayes to the line.
McCaffery was ejected with 12 minutes to play after two technical fouls were called.
Brust then hit all four free throws off the technical fouls, and Hayes converted one of two on the personal.
That turned a 41-39 Iowa lead into 44-41 Wisconsin advantage. Hayes then scored on a drive to cap a 12-2 run.
Roy Marble led Iowa (12-3, 1-1) with 27 points.
NO. 8 WICHITA ST. 67, N. IOWA 53: Fred VanVleet had a season-high 22 points to lead Wichita State to its 15th straight win.
Cleanthony Early had 18 points for Wichita State (15-0, 2-0 Missouri Valley), which established a school record for consecutive wins and extended the best start in school history. The previous record winning streak of 14 games came in 1953-54.
Deon Mitchell had 16 points for Northern Iowa (7-7, 1-1).
NO. 11 VILLANOVA 91, PROVIDENCE 61: JayVaughn Pinks-ton scored 19 points and Dylan Ennis had 17 for Villanova.
Pinkston dunked off the opening tip, and the Wildcats (13-1, 2-0 Big East) dominated from there, thrashing the Friars (10-5, 0-2), who beat them twice last season. The Wildcats hit 10 of their first 11 shots to build a 24-point lead.
Bryce Cotton scored 25 points for the Friars.
NO. 21 SAN DIEGO ST. 61, NO. 16 KANSAS 57: Xavier Thames scored 16 points, four on free throws in the closing seconds, and San Diego State held on to end Kansas’ 68-game non-conference winning streak at Allen Fieldhouse.
Kansas (9-4) had a chance to tie the game when Perry Ellis went to the free throw line with 11.9 seconds left. He made his first free throw but, after San Diego State (12-1) called a timeout to ice him, Ellis missed the second, forcing the Jayhawks to foul.
Thames made both free throws to give San Diego State a three-point lead, and the Aztecs fouled rather than allow Kansas to attempt a tying 3-pointer. Frank Mason missed the first and made the second, and Thames made two more foul shots with 4.6 seconds left to seal the win.
Skylar Spencer finished with 13 points for the Aztecs, who have won 11 straight since losing to No. 1 Arizona on Nov. 14.
Andrew Wiggins and Mason scored 14 points apiece for the Jayhawks, who had won 112 of their last 114 games at home.
WAKE FOREST 73, NO. 19 NORTH CAROLINA 67: Travis McKie scored 10 of his 16 points in the second half for Wake Forest in the Atlantic Coast Conference opener for both teams.
Codi Miller-McIntyre added 12 points for the Demon Deacons (11-3), who took control with a 15-2 run midway through the second half to build a double-digit lead.
The Tar Heels (10-4) made a late push to cut the deficit to 64-61, but the Demon Deacons held on for their third win against a ranked opponent under fourth-year coach Jeff Bzdelik.
James Michael McAdoo had 13 points and eight rebounds to lead the Tar Heels, and J.P. Tokoto and Brice Johnson each added 12 points and nine rebounds.
