LAWRENCE, Kan. (AP) – Perry Ellis had 27 points and 13 rebounds, Devonte Graham hit the go-ahead free throw in the third overtime and top-ranked Kansas outlasted Buddy Hield and second-ranked Oklahoma 109-106 on Monday night in an early showdown of Final Four contenders

Wayne Selden had 21 points and Graham finished with 20 for the Jayhawks (13-1, 2-0 Big 12), who had chances to win the game in regulation and each of the first two overtimes before finally getting it done.

Hield had a career-high 46 points for Oklahoma (12-1, 1-1), but he made two crucial turnovers in the final extra session, then missed a potential tying 3-pointer at the buzzer as the Jayhawks celebrated.

Jordan Woodard hit six 3-pointers and had 27 points for the Sooners, who were trying to extend their best start in 28 yards. Ryan Spangler finished with 14 points and 18 rebounds.
