LEXINGTON, Ky. (AP) - Top-ranked Kentucky gave up the first 11 points, still trailed at halftime and finally shook off a slow start to beat pesky Columbia 56-46 on Wednesday night.
In a college basketball season already marked by several big upsets, the Wildcats (10-0) got their toughest challenge yet from the Ivy League Lions. Columbia led for nearly 27 minutes before Aaron Harrison and the Wildcats took control.
Set to face North Carolina, UCLA and Louisville in their next three games, the Wildcats had trouble from the outset against Columbia (5-3). Coach John Calipari called a timeout as the Lions took an 11-0 lead.
The Wildcats clamped down on defense to make several stops in the second half and took the lead for good at 36-34 on Derek Willis' two free throws with 13:18 remaining.
Harrison scored 14 points and Willie Cauley-Stein added 10 points and 10 rebounds for Kentucky. Injured freshman guards Tyler Ulis and Devin Booker didn't play.
Maodo Lo scored 16 points for Columbia.
No. 5 WISCONSIN 93, MILWAUKEE 54
MILWAUKEE (AP) - Frank Kaminsky scored 18 points and Sam Dekker added 17 as Wisconsin extended its dominance over in-state rival Wisconsin-Milwaukee.
The Badgers (9-1) increased their winning streak to 22 games against the Panthers and their series lead to 31-1, completing a five-day Milwaukee sweep. Wisconsin defeated Marquette 49-38 on Saturday.
Matt Tiby with 17 points was the only player in double figures for the Panthers (4-6), whose lone victory in the series was 77-72 at Madison on Dec. 12, 1992.
Nigel Hayes added 13 points and Bronson Koenig added 10 for Wisconsin, which shot 60.9 percent from the field.
No. 9 GONZAGA 81, WASHINGTON STATE 66
SPOKANE, Wash. (AP) - Przemek Karnowski tied a career high with 22 points and Gonzaga beat Washington State.
Kyle Wiltjer added 21 points and Byron Wesley had 20 for Gonzaga (8-1), which was coming off an overtime loss at No. 3 Arizona.
Josh Hawkinson had 18 points and 11 rebounds for Washington State (4-5), which has lost four straight to the Bulldogs. DaVonte Lacy and Ike Iroegbu scored 14 apiece.
Gonzaga has won 31 straight home games, the second-longest streak in the nation.
Gonzaga star guard Kevin Pangos, who hit the floor hard when he was blocked by Jordan Railey while trying a layup in the opening minutes, was held scoreless for the first time in his career.
No. 10 KANSAS 75, GEORGETOWN 70
WASHINGTON (AP) - Brannen Greene went 5 for 5 from 3-point range and scored a career-high 19 points as Kansas made a basketball statement with a win over Georgetown, even as Hoyas players were making a societal statement by wearing "I CAN'T BREATHE" T-shirts for the national anthem.
Greene scored 16 in the second half, including two free throws that helped clinch the game in the final minute. Frank Mason added 14 points, and Perry Ellis had 13 points and 10 rebounds for the Jayhawks (7-1), who have won six straight.
Joshua Smith scored 20 points to lead the Hoyas (5-3), whose other losses came against No. 4 Wisconsin and No. 15 Butler.
Minutes before the opening tip, Georgetown's entire roster emerged for the final warmups wearing black, short-sleeve T-shirts with the words "I CAN'T BREATHE" in white. The players kept the T-shirts on during the anthem and pregame handshakes, then took them off for the announcement of the starting lineups.
They became the latest notable athletes to display words on warmups or other equipment in recent days, echoing the last words spoken by Eric Garner as police were attempting to arrest him in New York in July. A grand jury decided last week not to indict the officers involved in Garner's death.
No. 12 OHIO STATE 97, HIGH POINT 43
COLUMBUS, Ohio (AP) - Kam Williams scored a career-high 23 points, including 13 in a row for Ohio State in the first half against High Point.
D'Angelo Russell had 18 points, nine rebounds and five assists for the Buckeyes (7-1), who hit 35 of 56 shots from the field for 63 percent. Jae'Sean Tate scored 12, Shannon Scott added 11 points and seven assists, and Sam Thompson scored 10.
John Brown, averaging 19.6 points coming in, had 19 to lead High Point (6-3), from the Big South Conference.
No. 13 UTAH 65, BYU 61
PROVO, Utah (AP) - Delon Wright had 16 points and 11 rebounds to help Utah beat BYU.
Wright scored nine points in the second half and sparked a 10-0 run that helped the Utes (7-1) overcome a 31-30 halftime deficit. Wright also had two steals and was 6 of 7 on free throws.
Kenneth Ogbe added nine points and freshman forward Brekkott Chapman had eight first-half points.
Tyler Haws led BYU (7-3) with 23 points, and Kyle Collinsworth added 17.
Utah was 19 of 30 from the line, while BYU made only six of 10 free throws. Utah also outrebounded BYU 43-31.
No. 18 SAN DIEGO STATE 60, LONG BEACH STATE 59
SAN DIEGO (AP) - Dwayne Polee II hit a tying 3-pointer and JJ O'Brien made a go-ahead putback as San Diego State rallied with a 19-10 closing run to beat Long Beach State.
Polee scored 16 points for SDSU (7-2), which trailed by eight with 8 1/2 minutes left following the second of two 3-pointers by Mike Caffey.
Polee made a 3-pointer with 3:15 left to tie it. Winston Shepard had a steal and Angelo Chol missed from in close, but O'Brien scooped up the ball and put it back to give SDSU the lead for good, 56-54.
Long Beach State had a chance at the buzzer, but Travis Hammonds' desperation shot from midcourt bounced off the rim.
The Aztecs were coming off a 49-36 loss at Washington in which they shot only 20.4 percent.
Caffey made four 3-pointers and scored 20 points for Long Beach State (5-6), which played the first of four ranked opponents in a span of five games.
No. 19 MARYLAND 67, NC CENTRAL 56
COLLEGE PARK, Md. (AP) - Richaud Pack scored 17 points, Jake Layman added 15 and Maryland took control in the first half before coasting past North Carolina Central.
The Terrapins (9-1) used a 21-2 run to go up by 21. Maryland connected on five 3-pointers during the surge, including two apiece by Layman and freshman Jared Nickens.
It was the second win in a row for the Terrapins following their lone defeat, at home against Top 10 foe Virginia a week ago.
Jordan Parks had 18 points and 10 rebounds for the Eagles, whose five-game winning streak ended. NCCU (6-4) made only two field goals in the final 11 minutes of the first half and trailed 39-18 at the break.
No. 23 NORTHERN IOWA 65, DENVER 55
DENVER (AP) - Seth Tuttle had 12 points and Deon Mitchell scored nine of his 11 in the first half, when Northern Iowa missed only two shots from the floor against Denver.
Northern Iowa hit 15 of 17 attempts (88.2 percent) in the opening half to build a lead that stretched to 22 points. That cushion was enough as the Panthers held off a Pioneers squad that usually plays them tough, with all three of the previous meetings decided by six points or fewer.
The Panthers moved to 9-0 for the third time in school history. The last time Northern Iowa began with nine straight wins was 1963-64 under coach Norm Stewart.
Cam Griffin and Nate Engesser both had 15 points to lead Denver (4-4), which hasn't beaten a team in the Top 25 since knocking off Utah State in 1971.
No. 24 ST. JOHN'S 74, FAIRLEIGH DICKINSON 52
NEW YORK (AP) - D'Angelo Harrison scored 26 points and Phil Greene IV had 16 to lead St. John's past Fairleigh Dickinson.
Sir'Dominic Pointer added 12 points and Chris Obekpa had 10 points and 12 rebounds for the Red Storm (7-1) in their first game as a ranked team since 2011.
Obekpa also had six of the Red Storm's 11 blocked six shots. Harrison grabbed six rebounds and made all eight of his free throws.
Mustafaa Jones had 18 points for the Knights (3-5).
St. John's shot 56.9 percent from the field and held Fairleigh Dickinson to 37.3 percent, including 4 of 14 from 3-point range.
