Eron Harris scored a career-high 19 points Wednesday night to help lead West Virginia over TCU 71-50 in their first-ever meeting.
West Virginia's point total was its highest in five Big 12 Conference games.
The two opponents, in their first season in the Big 12, were fighting losing streaks coming in. The Mountaineers (9-9, 2-3) had dropped three straight, while TCU (9-10, 0-6) has lost six straight conference games for the first time since the 2001-02 season.
Harris, a freshman who has started the last three games, hit 5 of 6 shots, including 2 of 3 from 3-point range, and made 7 of 10 free throws to surpass his 17 points against Iowa State two games ago.
TCU was led by Kyan Anderson with 19 points.
Deniz Kilicli, starting for West Virginia for the first time since the Big 12 opener, scored 11 points and Jabarie Hinds added 10.
