ANN ARBOR, Mich. (AP) - Trey Burke had 15 points and eight assists and gave No. 2 Michigan a boost on defense, helping the Wolverines shake free of Purdue in the second half for a 68-53 win Thursday night.
Tim Hardaway Jr. added 13 points for Michigan, which has a chance to move to No. 1 in the next AP poll if it can win at Illinois on Sunday. Duke, the current top-ranked team, lost Wednesday.
The Wolverines (18-1, 5-1 Big Ten) trailed by seven in the first half, but Purdue (10-9, 3-3) couldn't keep up its torrid outside shooting. Terone Johnson scored 14 points for the Boilermakers.
Michigan took control with a 14-2 run in the second half. The Wolverines have won 28 of their last 29 home games - the only loss was to Purdue last February.
UCLA 84, NO. 6 ARIZONA 73
TUCSON, Ariz. (AP) - Shabazz Muhammad scored 23 points, Jordan Adams added 15 and UCLA rode a dominating start to an 84-73 win over No. 6 Arizona.
The Pac-12's top scoring and shooting team, UCLA (16-4, 6-1) tried to turn Arizona's whiteout into a blowout, racing to a 16-point lead in the game's first seven minutes.
David Wear added 15 points and eight rebounds for UCLA.
Arizona (16-2, 4-12) got off to a miserable start at both ends and never fully recovered, pulling no closer than four points after digging a huge opening hole.
Nick Johnson had 23 points, Mark Lyons added 16 and Solomon Hill 13 for the Wildcats, who went 5 for 24 from 3-point range.
NO. 10 GONZAGA 83, BYU 63
SPOKANE, Wash. (AP) - Kelly Olynyk scored 26 points and Elias Harris added 25 as No. 10 Gonzaga beat BYU 83-63 in a showdown for first place in the West Coast Conference.
Olynyk shot 9 for 9 from the field and 8 for 8 on free throws to go along with nine rebounds, and Harris had 10 boards for Gonzaga (18-2, 5-0), which was coming off a last-second loss at No. 9 Butler last weekend.
Josh Sharp and Brandon Davies led BYU (15-6, 5-2) with 14 points each.
Tyler Haws, the WCC scoring leader at 21 points per game coming in, was held to just one point for the Cougars. Haws had 42 points against Virginia Tech, the most by a Division I player this season. His previous low this season was nine points against Iowa State, and he had scored at least 20 in seven consecutive games coming in.
RICHMOND 86, NO. 19 VCU 74
RICHMOND, Va. (AP) - Kendall Anthony scored 21 of his 26 points after halftime and Darien Brothers hit two huge 3-pointers as Richmond needed overtime to end No. 19 VCU's 13-game winning streak.
Brothers had 18 points and Cedrick Lindsay 13 as the Spiders (13-7, 3-2 Atlantic 10) won for only the second time in their last nine meetings with the Rams. Richmond hit 12 3-pointers with Anthony making five and Brothers four, including one with 1.5 seconds left in regulation to force the overtime, and another to clinch it with 1:35 to play in OT.
Juvonte Reddic had 20 points and 10 rebounds and Treveon Graham had 15 points, all after halftime, and 10 rebounds for VCU (16-4, 4-1), which never got its ball-hawking havoc defense unleashed against the steady Spiders.
Both teams finished with 13 turnovers and scored 17 off their takeaways.
NO. 23 MISSISSIPPI 62, TENNESSEE 56
OXFORD, Miss. (AP) - Marshall Henderson scored 28 points, hitting six 3-pointers in the second half, and No. 23 Mississippi rallied for a victory over Tennessee.
Henderson is the Southeastern Conference's leading scorer with 18.9 points per game and he put on a show after the break, nearly single-handedly carrying the Rebels (16-2, 5-0) to their eighth consecutive victory. It's only the second time Ole Miss has started 5-0 in SEC play.
Tennessee (9-8, 1-4) led for much of the game, but couldn't withstand Henderson's hot shooting. Jordan McRae led the Volunteers with 26 points while Trae Golden added 11.
