STILLWATER, Okla. — Joey Graham and Ivan McFarlin each scored 20 points and Eddie Sutton moved into seventh place in career coaching wins as No. 6 Oklahoma State held off Iowa State for an 83-73 victory Saturday.

Sutton won his 768th game to pass Henry Iba, his mentor who coached him during his 36 years at Oklahoma State. After the game, school officials announced they would name the court at Gallagher-Iba Arena after Sutton.

John Lucas added 17 points and Stephen Graham scored 11 for the Cowboys, who won for the 24th straight time at home.

Curtis Stinson had 20 points to lead the Cyclones, Will Blalock scored 15, Jared Homan had 13 and Rahshon Clark 12. Iowa State has lost 27 consecutive Big 12 road games.

Daniel Bobik hit a fast-break layup to start an 11-4 run that put the Cowboys ahead 44-34 early in the second half, and Oklahoma State was in control from there.

McFarlin, Graham and Terrence Crawford had three-point plays as the Cowboys (13-1, 3-0 Big 12) used quick cuts to the basket to get around a sagging Iowa State (8-6, 0-3) zone defense that had slowed their offense in the first half.

By the time Bobik hit a 3-pointer in transition from the right wing, the Cowboys were comfortably ahead 56-42. On the Cyclones’ ensuing possession, Homan, their leading rebounder, was called for his third foul and coach Wayne Morgan was charged with two technical fouls and was ejected while arguing the call.

The Cowboys used the resulting free throws to add to their lead. Lucas hit three of the four shots after the technicals, and McFarlin added two more off Homan’s foul to make it 61-42.

With their coach gone, the Cyclones rallied for eight straight points and trailed 61-50 after Stinson’s 3-pointer from the left side.

Using a trapping defense, the Cyclones took advantage of Oklahoma State miscues and pulled within 75-70 following a 7-0 run that Blalock capped with two free throws with 2:16 to go.

Blalock made it 79-73 with a driving layup with just over 1 minute to play, but McFarlin drilled only his second 3-pointer of the season with the shot clock ticking down to ice the victory.

The Cyclones have lost 13 straight in Stillwater and haven’t beaten Oklahoma State at Gallagher-Iba Arena since March 2, 1988.
