The seedings for the NCAA West Regional matchup were close.
The game? Not so much.
No. 8-seeded Gonzaga defeated No. 9-seeded Oklahoma State 85-77 on Friday.
Gonzaga (31-4) was led by guard Kevin Pangos' 26 points, with 12 coming at the free-throw line.
Oklahoma State (21-13) was paced by guard Marcus Smart's 23 points, 13 rebounds, seven assists and six steals.
The Cowboys did not help their cause with some dreadful free-throw shooting. Oklahoma State converted just of 22 of 37 at the line (59 percent).
There were 61 fouls in the game and three Oklahoma State players -- forwards Le'Bryan Nash and Leyton Hammonds and center Kamari Murphy -- fouled out. Bulldogs guard Kyle Dranginis and forward Sam Dower Jr. were also disqualified with five fouls.
Gonzaga was up nine points at the half and by 12 after guard David Stockton opened the final 20 minutes with a 3-pointer. But Oklahoma State cut that lead to five before a layup by Gary Bell Jr. and a 3-pointer by guard Drew Barham stretched it to 10.
Oklahoma State pulled no closer than six in the next 13 minutes, with Gonzaga forging ahead 69-58 on Dranginis' two free throws.
The Cowboys did make a late run, but the game was not as close as the final score indicated.
The Bulldogs will play Arizona on Saturday for a trip to the Sweet 16.
Five minutes into the game, Oklahoma State had only one field goal, which led to a 15-4 deficit. Gonzaga had an 11-point lead twice in the first half before Oklahoma State went on a 10-0 run, fueled by seven points by Smart and a tip-in by Murphy.
But Gonzaga stretched its cushion back to seven points thanks to four buckets in the paint. It became a nine-point lead about four minutes before halftime after Dranginis sank a 3-pointer. But Smart, who had a team-high 12 points in the first half, hit a jumper to pull the Cowboys to 34-33.
Then the Bulldogs went on a 9-1 sprint to end the half that included 3-pointers from guards Drew Barham and Pangos.Copyright © 2015, RedEye
