"That's not characteristic of us," he said after missing four of his eight foul shots. "We are one of the best free-throw-shooting teams in the country."
Markel Brown had 16 points for Oklahoma State, which was coming off a loss to Kansas State in the Big 12 Conference Tournament last week.
NOTES: The Oregon matchup with Saint Louis on Saturday will be a reunion of sorts for the Ducks' Altman, formerly the coach of Creighton, the Billikens' long-time Missouri Valley Conference rival. "They play a little slower tempo than we like," Altman said. ... Amid speculation that Smart will be a one-and-done collegian, the Cowboys' Ford insisted, "There's no decision been made." ... Smart's five steals in the game gave him 99 this season and tied him with Brooks Thompson for the all-time Oklahoma State single-season record. ... The game was the second between Oregon and Oklahoma State. The Ducks prevailed the only time previously as well, 68-55 in the Far West Classic in 1997. ... Oklahoma State was making its 25th NCAA Tournament appearance and first since losing to Georgia Tech in 2010. ... The win was a marked contrast to Oregon's previous experience in the San Francisco Bay Area this season. With Artis out of the lineup, the Ducks were beaten 76-52 at Stanford on Jan. 30 and 58-54 at Cal three nights later. ... The Ducks were rooted on by former Portland Trail Blazers standout Bill Walton, a UCLA alumnus.
