Romero Osby scored 26 points, Steven Pledger chipped in 23 and Oklahoma led wire to wire for the fourth straight home game, beating West Virginia 83-70 on Wednesday night.
The Mountaineers (13-17, 6-11 Big 12) trimmed a 17-point deficit down to three in the opening minutes of the second half and were within four with 5 minutes left before Andrew Fitzgerald converted a three-point play off a driving layup before hitting a jumper on back-to-back possessions. Pledger followed with a 3-pointer that circled the rim before falling in to make it 76-64 with 3:16 remaining.
Sam Grooms tied his career best with 10 assists for the Sooners (20-9, 11-6), who moved another step closer to an NCAA tournament bid.
Eron Harris had four of his five 3-pointers in the second half and led West Virginia with 23 points. Deniz Kilicli scored 20.
