CHICAGO- Greg Oden scored 22 points – 15 in the second half – and No. 1 Ohio State won its 15th straight game, beating Michigan 72-62 Friday in the quarterfinals of the Big Ten tournament.

Oden scored 11 of his points in the final 8:27 after Michigan had pulled to within four.

Ohio State (28-3) hasn’t lost in two months – a defeat Jan. 9 at Wisconsin. The Buckeyes advance to a semifinal Saturday against Purdue, which beat Iowa 74-55.

The 7-foot Oden was 8-for-12 from the field and 6-for-10 from the free throw line to go with eight rebounds and four blocks.

It was Ohio State’s third win in as many tries this season against Michigan (21-12), which is hoping to make the NCAA tournament for the first time since 1998.

No. 3 Wisconsin 70, Michigan St. 57

CHICAGO – Alando Tucker, held to three free throws in the opening half, made four 3-pointers in the second half to lift Wisconsin over Michigan State in the Big Ten tournament quarterfinals.

Tucker, the league’s player of the year, finished with 21 points – his 39th straight game in double figures – and the Badgers (28-4) advanced to a semifinal Saturday.

Big 12

No. 2 Kansas 64, Oklahoma 47

OKLAHOMA CITY – Brandon Rush scored 16 points and ignited Kansas after an uninspired first half, lifting the Jayhawks past Oklahoma in the quarterfinals.

Rush started Kansas’ 18-2 second-half run with a reverse layup, and added a 3-pointer and a pair of free throws before the top-seeded Jayhawks (28-4) took it to another level, eventually leading by as many as 24 while Oklahoma struggled to make a shot.

Okla. St. 57, No. 7 Texas A&M 56

OKLAHOMA CITY – Mario Boggan scored from the right block with 11.5 seconds left to give Oklahoma State a victory over Texas A&M.

Boggan and David Monds scored 11 points apiece to lead the Cowboys (21-11), who rallied from nine points down in the second half and won after trailing at halftime for only the second time in 11 chances this season.

Big East

No. 9 Georgetown 84, No. 20 Notre Dame 82

NEW YORK – Jeff Green had a career-high 30 points, including the winning basket with 13 seconds left, and 12 rebounds to lead Georgetown over Notre Dame in the semifinals of the Big East tournament.

DaJuan Summers added 18 points and Patrick Ewing Jr. tied his career high of 15 to help the top-seeded Hoyas (25-6) advance to the final for the first time since 1996 with their 14th win in 15 games.

Boston College 74, Miami 71, OT

TAMPA, Fla. – Tyrese Rice scored a career-high 32 points, including a key 3-pointer near the end of regulation and two huge free throws in overtime, to propel Boston College to a 74-71 victory over Miami.

Rice carried the Eagles for much of the game and essentially picked up the slack for leading scorer and conference player of the year Jared Dudley, who finished with 12 points. Dudley was quiet most of the game but stepped up in overtime, hitting a jumper and then converting a three-point play that put fourth-seeded Boston College (20-10) ahead 72-71 with 1:51 remaining.

Southeastern Conference

No. 6 Florida 74, Georgia 57

ATLANTA – Florida scored the first 17 points of the game, built a 25-point lead before halftime and romped past Georgia in the quarterfinals of the Southeastern Conference tournament.

Taurean Green scored 19 points to lead the Gators (27-5). Takais Brown scored 12 points for Georgia (18-13).

Mississippi State 84, Kentucky 82

ATLANTA – Mississippi State found some defensive resolve and delivered the stunner of the SEC tournament on Friday.

Jamont Gordon forced an improbable overtime with a clutch three-point shot at the horn, and the Bulldogs scrambled past Kentucky in the extra five minutes, holding on for an 84-82 victory before a packed Georgia Dome.

Conference USA

No. 5 Memphis 71, Tulane 49

MEMPHIS, Tenn. – Chris Douglas-Roberts scored 17 points, and Memphis extended the nation’s longest winning streak to 21 straight by beating Tulane in the Conference USA tournament semifinals.

The top-seeded Tigers (29-3) will play either Rice or Houston in the championship Saturday. The regular-season champions will be playing for consecutive tournament titles on a court where they have won 31 consecutive games.

ACC

No. 8 UNC 73, Florida St. 58

TAMPA, Fla. – Wayne Ellington scored 18 points and Ty Lawson had 14 to lead North Carolina over Florida State in the quarterfinals of the Atlantic Coast Conference tournament.

The Tar Heels’ balanced attack was simply too much for the Seminoles’ one-man show, Al Thornton. FSU (20-12) never led, and Thornton – the ACC’s leading scorer and runner-up for conference player of the year – scored 12 points before fouling out with more than 6 minutes to go.

Brandan Wright added 11 points and Reyshawn Terry had 10 for North Carolina (26-6), which advanced to a semifinal Saturday against Boston College. The Eagles beat Miami 74-71 in overtime.

Tyler Hansbrough, whose nose was broken in North Carolina’s victory over Duke last Sunday, wore a protective mask and scored six points on 3-for-7 shooting before fouling out late in the game.
