SAN JOSE -- After winning the Pac-12 tournament, Oregon didn't care for being handed a No. 12 seed in the Big Dance.
The Ducks sent a message in Thursday's NCAA tournament Midwest Regional opener with a convincing 68-55 win over No. 5 Oklahoma State. It was the 26th time in the last 29 years that a 12th seed has beaten a fifth seed.
Oregon will play Saturday against No. 4 Saint Louis.
"That was a total team win," Oregon coach Dana Altman said. "I thought we beat them in every category. I'm really happy for the guys. They played really hard."
Oregon surged ahead early at HP Pavilion with an 8-0 run in the first half to grab a 19-12 advantage. The Ducks eventually added to it to take a 37-26 lead into halftime.
Oregon maintained a double-digit lead throughout the second half to earn its first NCAA tournament win since reaching the Elite Eight in 2007. It was the Ducks' fourth straight postseason win after running the table in the conference tournament.
"We're in a stretch where we feel real comfortable as a team and it's showing," Oregon freshman point guard Dominic Artis said.
Artis, a former Salesian High star from Vallejo, scored 13 points in his first collegiate game in the Bay Area. Altman said it was "absolutely" the best Artis has played since missing nine games with a stress fracture in his foot.
The Ducks were led by Damyean Dotson's 17 points.
Markel Brown paced Oklahoma State with 16 points,
According to Yahoo Sports, Smart was slated to receive X-rays after feeling pain in his right wrist.
Saint Louis 64, New Mexico State 44: Dwayne Evans had 24 points and six rebounds and the fourth-seeded Billikens (27-6) never trailed against the No. 13 Aggies (24-11) at HP Pavilion.
Saint Louis, whose coach Rick Majerus died in December, advances to Saturday's round of 32 to face Oregon.
"We're in the NCAA (tournament), that's awesome. Win a championship, that's absolutely awesome," said Billikens coach Jim Crews, who took over when Majerus took a medical leave of absence last summer. "But the maturity and the development that these guys have had, and just who they are and becoming, that's pretty cool from my standpoint."
Saint Louis led 29-16 at halftime and withstood New Mexico State's only extended run when the Aggies scored eight consecutive points in the second half.
Evans ended the run with a jumper and, moments later, Saint Louis began a 10-0 spurt that put the game away.
New Mexico State's Sim Bhullar, a 7-foot-5, 355-pound freshman, finished with four points, 11 rebounds and three blocks. Bhullar didn't match the production that earned him MVP honors at the Western Athletic Conference tournament.
