MINNEAPOLIS (AP) - Sam Jacobson scored a career-high 29 points and No. 8 Minnesota used another outstanding defensive effort to beat Iowa, 66-51.
The Golden Gophers held Iowa without a basket over a 10:38 stretch of the first half, then blew the game open by holding the Hawkeyes to just one hoop in a 6:05 span of the second half.
Jacobson, whose previous career high was 26 points, was 5-for-6 from 3-point range and gave Minnesota (6-1 Big Ten, 17-2 overall) the lead for good with an exhilarating dunk midway through the first half.
Guards Eric Harris and Bobby Jackson teamed to hold Iowa's Andre Woolridge, the Big Ten's leading scorer at 22 points a game, to 12 points on 3-for-14 shooting.
Daryl Moore added 11 points for the Hawkeyes (5-2, 14-5), and Guy Rucker had 10.
Wake Forest 65, Clemson 62
Fourth-ranked Wake Forest stopped Clemson's 12-game winning streak, beating the No. 2 Tigers 65-62 last night behind 16 points, 15 rebounds and five blocks from Tim Duncan.
The Demon Deacons (5-1 Atlantic Coast Conference, 14-1 overall), coming off a loss to No. 7 Maryland at home last week, withstood a second-half surge by Clemson, which closed a 12-point deficit to 63-62 with 15.1 second left.
The Tigers (5-1, 16-2) lost their chance to go ahead when Andrius Jurkunas was called for charging.
After Duncan made a free throw, Jurkunas missed a 30-footer at the buzzer.
Greg Buckner had 14 of his 19 points in the second half for Clemson.
Tony Rutland finished with 15 points for Wake, including a 3-pointer with 1:02 left that gave the Deacons a 62-57 lead. It was also Rutland who stepped in front Jurkunas to draw the foul.
Xavier 62, George Washington 61
In a battle for first place, the highest-scoring team in the country relied on some clutch defense.
T.J. Johnson, the only starter whose scoring average isn't in double figures, made a steal, drew a charge and batted away a pass in the final 90 seconds as No. 16 Xavier defeated George Washington, 62-61, last night to remain atop the West Division of the Atlantic 10.
The Musketeers (4-1 Atlantic Ten, 13-2 overall) came in averaging 88.4 points per game, but won their second straight with a scoring output below 70. Xavier beat Temple, 68-64, in overtime on Sunday.
George Washington (3-3, 8-7), which began the season in the top 25, has lost six of nine and missed a chance to win consecutive games for the first time since early December.
Guards Lenny Brown and Gary Lumpkin led Xavier with 12 points apiece and Johnson finished with 10.
Alexander Koul scored 20 to lead GW, but was exhausted over the final minutes despite sitting out most of the first half with foul trouble. Yegor Mescheriakov and Shawnta Rogers had 13 each.
With George Washington leading 61-60 with less than two minutes left, the Colonials milked the shot clock as they had virtually the entire game.
But with the 35-second clock running out, Johnson picked off Mescheriakov's attempt to feed Koul underneath. James Posey put in an offensive rebound on a fast break at the other end with 1:24 left for the final basket of the game.
George Washington had three chances to win, but Rogers charged into Johnson with 55.4 seconds to play, Braggs blocked J.J. Brade's inside shot with 1.5 seconds left, and Johnson tapped away an inbounds pass to Koul as time expired.
