STILLWATER, Oklahoma (Ticker) -- Ivan McFarlin had his best game of the season. Eddie Sutton had one of the best days of his life.
McFarlin had season highs of 20 points and 12 rebounds and Joey Graham sparked a huge run as No. 6 Oklahoma State pulled away for an 83-73 triumph over Big 12 Conference foe Iowa State.
McFarlin was 5-of-8 from the field and 9-of-11 from the line to help the Cowboys (13-1, 3-0 Big 12) to their 24th straight home win.
"I was really pleased that Ivan broke out of what I would call a semi-slump," Sutton said. "I don't think he has been playing as well as he did a year ago. He certainly had a banner game today. When you only take eight shots and you score 20 points, that is pretty productive."
The win moved Sutton into seventh place on the all-time list with 768 victories, one more than his mentor and former Oklahoma State coach Henry Iba. In a ceremony after the game, the school officially named the court at Gallagher-Iba Arena as "Eddie Sutton Court."
"It means a great deal. It is quite an honor," Sutton said. "I was really surprised, because I didn't know that it was going to happen. I would never have been able to go to college without a scholarship, and coach Iba gave me one."
"This win makes us all feel real good. Now we have to keep winning so that the numbers continue to pile up," Oklahoma State guard John Lucas said.
Graham scored seven points during a 12-5 run to close the first half and give the Cowboys a 30-28 lead. He had a pair of 3-pointers and a three-point play to key a 13-6 run that opened the second half and increased the lead to 43-34 with 15:17 to play.
The Cyclones closed to 75-70 on two free throws by Will Blalock with 2:17 to play, but Daniel Bobik sank a free throw and John Lucas converted a layup to push the lead to 78-70 with 1:49 remaining.
"It was a strange game in that we were so passive offensively in the first half," Sutton said. "I thought in the second half we started playing really well offensively and our defense was quite good.
"That's a game where you ought to win going away by 25 or 30 points. Then we just quit playing again. The defense was non-existent, we couldn't contain the dribble penetration. ... I'm happy we won the game but disappointed in the last eight to 10 minutes of the game."
The win was the 24th straight at home for the Cowboys, tying for the fifth-best mark in school history. Oklahoma State won 24 straight at home from February 2, 1994-January 8, 1996.
Graham made 7-of-10 shots and 4-of-4 free throws. He has made 31 straight foul shots, five shy of the school record held by Hollis Price. Lucas added 17 points and seven assists for OSU, which shot 50 percent (27-of-54) from the floor.
"Joey and Ivan stepped up today for us," Lucas said. "I was able to penetrate, dish and get my teammates more involved. Godo things happen when stuff like that goes on."
Curtis Stinson scored 20 points and Blalock added 15 for Iowa State (8-6, 0-4), which shot 51 percent (28-of-55) but was outrebounded, 34-25, including 13-8 on the offensive glass.
"We went out there and played together," Iowa State forward Jared Homan said. "We gave them a good run but we would've liked to win. We are excited with the direction we are going and that we're climbing uphill."
