STILLWATER, Okla. — Kevin Pangos scored 23 points and hit the clinching free throws with 4.3 seconds left, Kelly Olynyk scored all 21 of his points in the second half and No. 10 Gonzaga edged No. 22 Oklahoma State 69-68 on Monday night to spoil one of the Cowboys' most anticipated nonconference games at Gallagher-Iba Arena in decades.
Marcus Smart led Oklahoma State (10-2) with 23 points but missed two free throws with 8.7 seconds left with the Cowboys trailing by two. Elias Harris grabbed the rebound on Smart's second miss, and Pangos was fouled in the backcourt before stepping to the line to drill both free throws.
Phil Forte then connected on a 3-pointer at the buzzer for Oklahoma State. Markel Brown contributed 16 points and Forte scored 15 for the Cowboys.
Gonzaga (13-1) completed a perfect five-game sweep of Big 12 competition in nonconference play.
