Jahlil Okafor powered Duke into the Sweet 16. 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, N.C. — Travis Trice scored 23 points, and Michigan State knocked second-seeded Virginia out of the NCAA Tournament 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.

Oklahoma 72,Dayton 66

COLUMBUS, Ohio — Jordan Woodard had 16 points and Buddy Hield scored 15, helping Oklahoma advanced to the second weekend of the tourney.

Coach Lon Kruger became the second coach to take four schools (Kansas State, Florida and UNLV) 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.

The Cardinals will play eighth-seeded North Carolina State on Friday in an East Region that is now missing the top two seeds.

The Cardinals packed it in against Northern Iowa’s top scorer, Seth Tuttle, holding him to 14 points.

Duke 68, San Diego State 49

CHARLOTTE, N.C. — 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

OMAHA, Neb. — No wonder Kansas never wants anything to do with Wichita State.

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.

Wisconsin 72, Oregon 65
