Georgetown's Jason Clark drives the lane for a shot against Butler.

NEW YORK — Greg Monroe had 24 points and 15 rebounds — both career highs — to lead No. 15 Georgetown to a 72-65 victory over No. 22 Butler on Tuesday night in the Jimmy V Classic at Madison Square Garden.

Monroe, last season's Big East rookie of the year, recorded his third double-double of the season as the Hoyas (7-0) used their size advantage to control the paint at both ends.

Georgetown finished with a 43-30 rebounding advantage, outscored the Bulldogs (6-3) 30-16 inside and held Butler forward Matt Howard to nine points on 1-of-9 shooting.

The loss was the third in as many games against ranked teams for Butler, which hosts No. 13 Ohio State on Saturday. The Bulldogs, who lost to Minnesota and Clemson in the 76 Classic, have lost eight of their last nine games against teams in Top 25.

Austin Freeman was 4-of-5 from 3-point range and added 18 points for the Hoyas.

Gordon Hayward had 24 points for Butler.

The 6-foot-11 Monroe, who scored 21 points against Notre Dame as a freshman and had 13 rebounds against American last weekend, started slowly from the field, missing four of his first six shots. His defense against Howard was strong from the start as the 6-8 junior and reigning Horizon League player of the year missed his first eight shots from the field, many with Monroe having a hand in his face or leaning on him as he tried to establish position down low.

The Hoyas did go outside to take their biggest lead of the game as Freeman hits two 3-pointers and Hollis Thompson made another from long range to make it 52-35 with 13:35 to play.

The Bulldogs went on a 7-0 run — that included Howard's first field goal, to get to 52-42. Monroe was all alone at the other end of the court for a monster dunk to end Georgetown's 4:13 scoreless drought. But Howard made two free throws and Hayward hit a 3 to get the Bulldogs to 54-47 with 8:37 to go.

Butler was at 68-62 in the final minute when Monroe blocked a drive by Shelvin Mack and the Hoyas closed it from there.

The Jimmy V Classic is held annually to raise money for the V Foundation, the cancer research organization founded in the name of the late Jim Valvano.

NO. 23 TEXAS TECH 80, TCU 70: At Fort Worth, Texas, John Roberson scored eight of his 21 points in a game-turning run that finally put No. 23 Texas Tech ahead as the Red Raiders overcame an early 14-point deficit to beat TCU.

The Red Raiders (9-0) played their first game as a ranked team since the end of the 2004-05 season, and first for Pat Knight since he succeeded father Bobby as coach in February 2008. They are off to their best start in 80 years — since a 12-0 start in 1929-30 — and moved into the rankings Monday.

Zvonko Buljan had 24 points and 10 rebounds for TCU (5-4).

Texas Tech didn't lead until Theron Jenkins made a free throw with 16:09 left to break a 44-all tie. He was intentionally fouled at midcourt after stealing a pass and the whistle nullified his breakaway slam dunk.

The Red Raiders then maintained possession because of the intentional foul, and Roberson hit a 3-pointer. After a TCU miss, Brad Reese hit a 3 to make it 50-44, culminating the 24-3 run that wiped out their 14-point deficit. Roberson also had a 3-pointer in the closing seconds of the first half, when Tech scored the final nine points.

Mike Singletary had 17 points and David Tairu 14 for the Red Raiders. D'wayln Roberts had nine points and 19 rebounds.

Ronnie Moss had 11 points for TCU, and Garlon Green added 10.
