Kansas has won 12 consecutive Big 12 titles and has not lost at home to West Virginia since the Mountaineers joined the conference in 2012-13.
The recap, plus the regional scoreboard, is below.
Mason led the Jayhawks (23-3 11-2 Big 12) with 24 points, going 16-18 from the free throw line. Kansas made a few mistakes late, too, but it closed the door on the comeback by outscoring WVU 13-9 in overtime led by two Graham threes, with Mason icing the game with a pair of free throws with seven seconds left.
The Mountaineers would swell the lead to as many as 14-points seemingly in total control with under three minutes left, but Kansas would make a run to cut the score to 64-55 with 2:18 remaining to play in the game.
Four turnovers and four missed free throws were two of the biggest culprits in the West Virginia collapse.
Niem Stevenson had 21 points, six rebounds and five assists with Justin Gray ending with 13 points and 10 rebounds and Zach Smith scoring 11 points for the Red Raiders, who shot 51.1 percent.
The Jayhawks shot just 34 percent from the field, 35 percent from beyond the arc and missed countless layups and easy shots at the basket.

KU's full-court press forced WVU's fourth turnover in the final two minutes of regulation on an errant pass that went out of bounds. The score was tied on the board when overtime started, obviously, but the game's flow made it feel like Kansas was up by two possessions.
Mason, however, capped the regulation comeback by making both ends of a two-shot foul with 21.6 seconds remaining to tie the game at 71. Ahmad hit a jumper to end a stretch of 3:09 without a point, and a 3 from Adrian reset the 11-point lead at 21-10. Maybe he just knew how good the Kansas basketball team is and knew they're not out of the game until the final buzzer. Graham also contributed heavily, scoring 18 points, while Jackson had 14 and 11 rebounds and Lagerald Vick gave the Jayhawks a big boost off the bench with 14 points. It was a huge victory on many levels as it helps secure the Jayhawks name in the running for a No. 1 seed in March, while also showing that KU has a resiliency that sets it apart from the other contenders this season. As mentioned, the Mountaineers led by seven at halftime and every time Kansas threatened to make a run, there was an answer from Tarik Phillip or Elijah Macon. Ahmad's 20 points, meanwhile, paced the Mountaineers.
Considering West Virginia trails first-place Kansas by two games, a sweep of the season series looks nearly essential to fulfill any title hopes the Mountaineers possess.
With less than three minutes remaining in the second half, the message finally sunk in.
"I think we're excited to play", Huggins had said before the game.
An 8-0 run by the Mountaineers to close the half gave them a 39-32 margin at the break.
