Georgia Tech and Duke completed the NCAA's Final Four line-up when they won through to the national semi-finals on Sunday.

Jarrett Jack was Georgia's hero, scoring a career-high 29 points as the Yellow Jackets beat Kansas 79-71 in overtime to reach the Final Four for only the second time in their history and the first time since 1990.

Georgia looked to be struggling without injured leading scorer BJ Elder, but Jack filled the void and his four from four from the line with 47 seconds remaining clinched the victory.

That win denied Kansas a third successive Final Four place, and earned the third-seeded Yellow Jackets a game with Oklahoma State on Saturday.

Duke booked the Final Four berth with a 66-63 win over Xavier, who had already beaten the region's second and third seeds on their way to this stage but came unstuck against the top side.

The Musketeers' chances died when star player Anthony Myles fouled out with 12 and a half minutes remaining.

Luol Deng top scored for the Blue Devils, who now face Connecticut in Saturday's semi-finals.
