Here's what happened in the Elite Eight matchups in the NCAA men's basketball tournament on Saturday:

(2) Oklahoma 80, (1) Oregon 68

Buddy Hield hit eight 3-pointers while scoring 37 points, and Oklahoma advanced to its first Final Four since 2002 with a victory over Oregon in the West Region final of the NCAA Tournament.

Jordan Woodard added 13 points for the Sooners, who streaked to an 18-point lead in the first half and never let the Ducks back in it.

The regional final was a monument to the formidable talent of Hield, the Sooners' senior star. He produced a dynamite performance on his biggest stage, carving the Ducks' defence from all distances with his smooth outside shot and a knack for momentum-swinging buckets.

Elgin Cook scored 24 points for the Ducks, whose 11-game winning streak ended one game shy of the second Final Four in school history.

Montreal's Chris Boucher had 14 points and 10 rebounds for Oregon while Mississauga, Ont., native Dillon Brooks had seven points.

(2) Villanova 64 (1) Kansas 59

Kris Jenkins made two free throws with 13.3 seconds remaining, Jalen Brunson added two more with 3.5 seconds left and second-seeded Villanova upset top-seeded Kansas on Saturday night in the NCAA Tournament South Region final to reach the Final Four.

Mikal Reynolds and Josh Hart each made big steals in the final minute to help the Wildcats pull off the upset and end the Jayhawks' 17-game winning streak. The Wildcats are back in the Final Four for the first time since 2009, and they can credit balanced scoring and ferocious defense.

Jenkins, Hart and Ryan Arcidiacono each scored 13 points for the Wildcats, who used a 10-0 run to take a 50-45 lead and get key baskets and plays down the stretch in beating the Jayhawks.

Devonte' Graham had 17 points, and Frank Mason III and Wayne Selden Jr. added 16 each for Kansas.
