BUFFALO, N.Y. — Da'Sean Butler accounted for 19 of West Virginia's 30 points in the first half, then finished with 28 to lead the second-seeded Mountaineers to a 68-59 victory over 10th-seeded Missouri in the second round of the NCAA tournament on Sunday.

Kevin Jones had 13 points and nine rebounds for the Big East Conference champions.

Michael Dixon scored 15 points for Missouri (23-11), which was undone by an overall poor-shooting performance. The Tigers went 20 of 61 from the field and were just as bad from the free-throw line, where they went 12 of 20.

West Virginia (29-6) advances to face No. 11 seed Washington in the round of 16 at Syracuse on Thursday. It marks the fifth time the Mountaineers reached the final 16, and first since 2008.
