PHOENIX Three-pointers saved Xavier. Missed free throws doomed West Virginia.
B.J. Raymond made two 3-pointers in the last 1:18 of overtime Thursday night, and the Musketeers advanced to the West Region final with a 79-75 victory over coach Bob Huggins' Mountaineers.
Third-seeded Xavier (30-6) rallied from a six-point deficit in overtime and will seek its first Final Four appearance when it plays UCLA on Saturday.
Raymond, who had made only one field goal all night, hit a 3-pointer from the top of the key to put the Musketeers ahead 75-74 with 1:18 to play. He then shook loose on an inbounds play, took a crosscourt pass and made a 3 with the shot clock expiring with 30 seconds to go for a 78-74 lead.
Josh Duncan scored a career-high 26 points despite foul trouble to lead Xavier. Raymond's eight points all came in overtime.
Xavier, which led by 18 early in the game, rallied from a 71-65 deficit in overtime.
Joe Alexander scored 18 and had 10 rebounds for the Mountaineers (26-11).
West Virginia missed four of six free throws in the overtime. Alexander missed one with 14.2 seconds left in regulation that would have given his team a 65-64 lead.
Xavier shot 11-for-19 on 3s while West Virginia was 1-for-11 from long range. The Mountaineers had only one worse performance on 3s this season, going 1-for-22 in a loss to Cincinnati.
Duncan was 3-of-4 on 3s, Lavender 3-of-6 and Raymond 2-of-4. Da'Sean Butler added 16 points, 14 in the second half. Alexander and Butler both fouled out in the overtime.
Xavier has been in a regional final only once, in 2004.
Despite the loss, Huggins has had quite the comeback with the school he played for. Out of work two years ago, he barely missed taking a team to the regional final for the fourth time.
Huggins got fired at Cincinnati a school he led to the 1992 Final Four after a drunken-driving arrest and sat out a season before surfacing at Kansas State in 2007. He guided that team to the NIT, where it lost in the second round.
