DALLAS — Derrick Rose scored 19 points and Chris Douglas-Roberts added 18, leading No. 2 Memphis past SMU 72-55 on Wednesday night, extending the Tigers' road winning streak to 18 games.

Memphis (29-1, 15-0 Conference USA) finished unbeaten on the road for the first time since 1960-61, going 10-0.

This was the Tigers' 38th straight league victory and the 100th Conference USA win for coach John Calipari. He is 100-25 in eight seasons with the Tigers.

Jon Killen had 16 points for the Mustangs (9-19, 3-12).

Rose finished 8-of-14 for the field and Douglas-Roberts went 9-of-18.

NO. 4 TENNESSEE 89, FLORIDA 86: At Gainesville, Fla., JaJuan Smith scored 23 points and Chris Lofton added 21 as Tennessee overcame a 16-point deficit.

The Volunteers (27-3, 13-2 Southeastern Conference) set a school record for victories and may have knocked the two-time defending national champions out of the NCAA tournament picture.

The Gators (21-9, 8-7) have lost six of their last 10 and might need to win the SEC tournament to earn a 10th consecutive NCAA berth.

Nick Calathes had 24 points and nine assists for Florida, which had two chances to send it to overtime, while Marreese Speights added 21 points and seven rebounds.

NO. 6 DUKE 86, VIRGINIA 70: At Charlottesville, Va., Gerald Henderson scored 19 points for Duke, which will play top-ranked North Carolina for the ACC regular-season championship on Saturday night.

Kyle Singler scored 13 of his 18 points in the second half for Duke (26-3, 13-2 Atlantic Coast Conference), while DeMarcus Nelson had 16, Greg Paulus 14 and Jon Scheyer 10. The Blue Devils hit 12 3-pointers and shot almost 51 percent from the field.

NO. 10 WISCONSIN 77, PENN STATE 41: At Madison, Wis., Marcus Landry scored 15 points for Wisconsin, which clinched at least a share of the Big Ten regular-season championship.

It is the third time in seven seasons the Badgers (25-4, 15-2) have claimed at least a share of the conference title under coach Bo Ryan. Wisconsin finishes the regular season at Northwestern on Saturday and a victory would mean the outright championship.

NO. 16 VANDERBILT 86, MISSISSIPPI STATE 85 (OT): At Nashville, Tenn., Shan Foster, Vanderbilt's all-time leading scorer, had a career-high 42 points and hit his final nine 3-point attempts, the last with 2.7 seconds left in overtime.

The Senior Night victory allowed Vanderbilt (25-5, 10-5) to finish unbeaten at home this season and kept alive its chances at a first-round bye in the Southeastern Conference tournament. The Commodores finished 19-0 in Memorial Gym where they have won 32 of 33 games.

Jamont Gordon had 24 points for the Bulldogs (20-9, 11-4), who had a three-game winning streak snapped.

NO. 18 INDIANA 69, MINNESOTA 55: At Bloomington, Ind., Eric Gordon scored nine of his 20 points during a decisive late run in D.J. White's final home game.

It also may have marked the final home appearances for interim head coach Dan Dakich and Gordon, the freshmen star who is expected to leave for the NBA after this season.

Dakich improved to 3-1 since replacing Kelvin Sampson last month and the Hoosiers (25-5, 14-3) stayed in contention for the Big Ten regular-season title with their school-record 17th home victory.

White, a senior forward, had 17 points and five rebounds before departing to a loud ovation with about a minute left.

Indiana, which has won 25 regular-season games for the first time since 1992-93, is tied for second in the conference with Purdue, one-half game behind Wisconsin (14-2).

NO. 19 NOTRE DAME 68, ST. JOHN'S 55: At South Bend, Ind. , Luke Harangody scored 20 points and Notre Dame became the first Big East team to go undefeated at home in conference play in consecutive seasons.

The Fighting Irish (23-6, 13-4) opened a 10-point lead late in the first half and kept it in double digits most of the rest of the way. Kyle McAlarney, who finished with 13 points, hit a 17-foot jumper with 1:13 left to extend the lead to 68-50.
