IOWA CITY – Jarrod Uthoff kept No. 9 Iowa from falling too far behind.
Once his teammates joined in, Purdue didn't stand a chance.
Uthoff scored 13 of his 22 points in the first half and Iowa toppled No. 22 Purdue 83-71 Sunday for its ninth consecutive victory.
Adam Woodbury added 13 points and 10 rebounds for the Hawkeyes (16-3, 7-0 Big Ten), who have beaten four ranked teams since late December ahead of Thursday's meeting at No. 7 Maryland.
Iowa, which ran its home winning streak to 13 games, broke open a tight game with a 23-6 run to start the second half, getting baskets from seven different players during that stretch. But the Hawkeyes again were led by Uthoff, who entered Sunday as the leading scorer and shot blocker in the Big Ten.
"He's a special player. He's one of the best players in the country," Iowa point guard Mike Gesell said. "He can go off at any time."
Vince Edwards had 19 points and P.J. Thompson had 16 for Purdue (17-4, 5-3), which has split its past six games after a 14-1 start.
Iowa cemented its status as a Big Ten contender with a 70-63 win over Purdue earlier this month, outscoring the Boilermakers 50-26 in the second half in West Lafayette.
The Hawkeyes might have effectively knocked Purdue out of the league race by blowing past the Boilermakers yet again in the second half.
Purdue focused on stopping Uthoff, up by two after the break. But Uthoff drew the defense away for a pair of easy layups by Woodbury. Uthoff drove the lane for a lefthanded dunk the next time he touched the ball, giving Iowa its biggest lead to that point, 47-39.
"They're a tough team for us to match up against because of their skill and the way they move the ball. They're very unselfish," Purdue coach Matt Painter said.
