Ashton Gibbs scored 17 points, including three free throws in the final 17 seconds, and No. 15 Pittsburgh beat Oklahoma State 74-68 on Saturday, the Cowboys' third loss of the season and all of them at Madison Square Garden.
The Panthers (9-1) led by as many as 16 points in the second half, but Oklahoma State was able to get within five twice late. Each time, Gibbs was able to make at least one free throw.
Pittsburgh dominated the rebounding (43-25) and outscored the Cowboys 40-26 in the paint.
Gibbs had eight points - including two 3s - in Pitt's 17-7 run to close the first half that gave the Panthers a 42-30 lead.
Pittsburgh extended the lead to 16 points three times, the last at 59-43 on a basket by Patterson with 9:03 to play.
The Cowboys, who started the second half by missing 13 of their first 17 shots, later rallied.
Oklahoma State got within 71-66 with 20 seconds to play when Markel Brown stole a pass, scored and was fouled. He missed the free throw and Gibbs made two foul shots one second later. Reger Dowell's layup with 10 seconds to go made it 73-68 but Gibbs made one of two from the line. The miss was his only one of the game as he finished 7 of 8 and the Panthers were 18 of 29. The Cowboys were 9 of 13 from the free throw line.
After the poor start to the second half Oklahoma State finished 14 of 33 from the field (42.4 percent) in the final 20 minutes.
