Jahlil Okafor powered Duke into the Sweet 16 stage of the college basketball playoffs. There was no such luck for a pair of No. 2 seeds in Kansas and Virginia.
Kansas lost to Wichita State in a victory for an upstart school thirsting for a shot against the Jayhawks. And Michigan State continued its March success under coach Tom Izzo thanks to Travis Trice, who took command from the start to hand the ACC its first loss in this NCAA Tournament.
A look at how teams fared Sunday in the round of 32:
MICHIGAN STATE 60, VIRGINIA 54
CHARLOTTE, North Carolina (AP) -- Travis Trice scored 23 points, and Michigan State knocked second-seeded Virginia out for the second straight year.
Branden Dawson added 15 points and nine rebounds for the seventh-seeded Spartans, who advanced to the Sweet 16 for the seventh time in the last eight seasons under coach Tom Izzo. The Spartans will play the winner of the Oklahoma-Dayton game in Syracuse, New York on Friday.
OKLAHOMA 72, DAYTON 66
COLUMBUS, Ohio (AP) -- Jordan Woodard had 16 points and Buddy Hield scored 15, helping Oklahoma advanced to the second weekend of the tournament.
Coach Lon Kruger became the second coach to take four schools (Kansas State, Florida and University of Nevada Las Vegas) to the round of 16. Third-seeded Oklahoma (24-10) will play Michigan State on Friday at the East Regional in Syracuse, New York.
LOUISVILLE 66, NORTHERN IOWA 53
SEATTLE (AP) -- Louisville is headed to the Sweet 16 for the fourth straight year.
Terry Rozier scored 25 points to lead the fourth-seeded Cards to the victory. Montrezl Harrell added 14 for Louisville (26-8), including a couple of game-sealing alley-oop jams on passes from Rozier.
DUKE 68, SAN DIEGO STATE 49
CHARLOTTE, North Carolina (AP) -- Jahlil Okafor scored 18 of his 26 points in a dominating first half and Duke beat San Diego State 68-49 on Sunday in the NCAA Tournament, sending the top-seeded Blue Devils back to the Sweet 16.
Fellow freshman Justise Winslow added 13 points and 12 rebounds for Duke (31-4), which for the second straight tournament game ran out to a quick lead and stayed in control the rest of the way.
GONZAGA 87, IOWA 68
SEATTLE (AP) -- Kyle Wiltjer scored 13 of his 24 points during Gonzaga's flawless first half, helping the Bulldogs advance to the round of 16 for the first time since 2009.
After five straight departures on the first weekend of the NCAA tourney, Gonzaga (34-2) is back in the regional semifinals, thanks to an efficient offensive performance in the first 20 minutes that Iowa could never overcome. Domantas Sabonis finished with 18 points.
WICHITA STATE 78, KANSAS 65
OMAHA, Nebraska (AP) -- Behind another steady performance from Fred VanVleet and the hot shooting of Evan Wessel, the No. 7 seed Shockers rolled past the second-seeded Jayhawks 78-65 on Sunday, earning a trip to the Sweet 16 at the expense of the school that has caused them so much chagrin.
Tekele Cotton led the way with 19 points for the Shockers (30-4). VanVleet finished with 17 and Wessel hit four 3-pointers and scored 12, sending the Missouri Valley champions to Cleveland for the Midwest Regional semifinal against third-seeded Notre Dame.
WEST VIRGINIA 69, MARYLAND 59
COLUMBUS, Ohio (AP) -- Devin Williams had 16 points and 10 rebounds, and rugged West Virginia advanced to a Sweet 16 showdown with undefeated Kentucky.
Gary Browne scored 14 points and Daxter Miles Jr. had 12 as West Virginia reached the second weekend of the tournament for the first time since 2010, when it went all the way to the Final Four. The fifth-seeded Mountaineers (25-9) will take on the Wildcats on Thursday night in the Midwest Regional semifinals in Cleveland.
WISCONSIN 72, OREGON 65
OMAHA, Nebraska (AP) -- Sam Dekker scored 17 points for balanced Wisconsin, which beat Oregon in the round of 32 for the second straight year.
Next up for the Badgers (33-3) is a trip to Los Angeles to play fourth-seeded North Carolina in the Sweet 16 on Thursday.
Wisconsin played with the lead all game until Dwayne Benjamin tied it at 52 with a high-arcing 3-pointer from in front of his bench with 5:27 left. But Dekker responded with a reverse layup and 3-pointer to make it 58-52.
