LAKE BUENA VISTA, Fla. – Marcus Smart scored 17 points as No. 5 Oklahoma State survived a major scare in a 69-67 win over Butler in an Old Spice Classic semifinal on Friday.

Oklahoma State (7-0) again came out flat to start a second half, one day after the Cowboys saw a 23-point halftime lead dwindle to four with 3 minutes to play before beating Purdue 97-87.

With the Cowboys holding a 68-67 lead in the final minute, Smart missed three free throws, including the front end of a 1-and-1.

Butler's Khyle Marshall was fouled with 8.4 seconds remaining, but also missed his free throws.

Le'Bryan Nash made it 69-67 by hitting 1 of 2 from the line before Butler's Elijah Brown had his last second 3-point shot blocked.

Butler (5-1) got 15 points from Brown.
