BUFFALO, N.Y. -- Eddie Sutton got his wish for Oklahoma State's seven seniors.
Paced by center Fredrik Jonzen's 21 points and two clutch 3-pointers from Joe Adkins, the Cowboys broke open a close game in the second half Sunday and beat Pepperdine 75-67 to advance to the East Regional semis.
"I wanted so much to get to the Sweet 16 with this team because those seniors have been a very special group," said Sutton, whose team lost in the second round the past two years.
"I told them that I thought they were good enough to get there, and when you get there anything can happen. It's down to 16 ballclubs."
Oklahoma State faces Seton Hall Friday in Syracuse, N.Y.
Oklahoma State and Pepperdine were coming off 20-point victories in the first round. The third-seeded Cowboys (26-6) beat 14th-seeded Hofstra 86-66 and No. 10 Pepperdine (25-9) defeated No. 6 Indiana 77-57.
This one was a fight for 30 minutes. The Waves, who press at every turn, befuddled the Cowboys at the outset and built a 5-1 lead. Sutton had seen enough and called a timeout.
"When we came out, (the Waves) had great energy level and we were down," said Cowboys point guard Doug Gottlieb, who finished with nine assists and five points. "And Coach, instead of going nuts sat us down and said, `Look, now let's start playing. You obviously know they can play. Relax and play."'
And the Cowboys did.
Jonzen's strong inside game -- he scored 12 of his points in the first half -- allowed them to take a 35-31 lead at the break.
"We talked about that before the game, saying we had to get the ball inside," said Jonzen, who had 13 points and 11 rebounds against Hofstra. "The high post was wide open. That was one of the main keys -- getting the ball inside."
