COLUMBIA, Missouri (Ticker) -- Arthur Johnson continues to make his considerable presence felt.
Johnson collected 21 points and 11 rebounds and Ricky Clemons sparked a late run as No. 20 Missouri posted a 64-59 Big 12 Conference victory over Iowa State, snapping a two-game slide.
It was the 10th double-double of the season for Johnson, who averages 17.1 points per game. The 6-9, 265-pound sophomore is averaging 19 points and 12.5 rebounds in his last six games.
"I was tired, but it was just time we turn up the defense and try to create offensively so we could get up a little bit and have some breathing room," Johnson said.
Clemons returned after being suspended for Saturday's loss to Oklahoma State for his arrest on a domestic assault charge. He was greeted by cheers by the 11,627 fans at Hearnes Center and all indications are that his case will go to trial after the season.
"I said before, everybody's entitled to their opinion," Missouri coach Quin Snyder said. "I believe Ricky - otherwise he wouldn't be playing. I was pleased with that reception. Our fans were great tonight."
Clemons' play helped rally the Tigers after Iowa State (10-5, 0-4 Big 12) took a 50-47 advantage on consecutive baskets by Chris Alexander.
A 3-pointer by Travon Bryant tied the game and triggered a 13-0 tear by Missouri (11-3 2-1). A pair of foul shots by Clemons gave the Tigers the lead for good with just over six minutes left.
Freshman Jimmy McKinney nailed a jumper and Clemons added a pair of baskets to make it 60-50 with 2:42 left. The Tigers held the Cyclones scoreless for over five minutes.
"I was pleased with how our kids fought tonight," Snyder said. "Those are the type of games, as a coach, you work toward - when you're not shooting well, things aren't going well and you need to do other things to win the game."
Clemons and Rickey Paulding each scored 15 points for Missouri, which survived 36 percent (23-of-64) shooting. The Tigers made 13-of-17 foul shots and Johnson, a 54 percent foul shooter, sank all five.
Missouri improved to 9-0 at home and has won 12 straight games against unranked competition.
"Iowa State always plays us tough," Bryant said. "We really expected them to come out and play their best for 40 minutes, so we just went out there with the mentality that we have to execute our offense and play good defense."
Iowa State was led by freshman Adam Haluska's 15 points. Alexander and Jake Sullivan each finished with 10 points.
"I'm as disappointed as I've been in a long time," Cyclones coach Larry Eustachy said. "This is a team we had a chance to beat and just didn't have the toughness to do it."
The Cyclones scored the game's first six points and were competitive in the early going. Haluska scored 11 points in the first half as Iowa State went to the locker room trailing, 29-28.
Missouri grabbed 19 offensive rebounds, including six by Johnson. The Tigers had just nine turnovers, in comparison to 19 for the Cyclones.
