Flowers followed Mitchell's missed 3-point try with a basket to cap a 9-0 run and West Virginia extended an 11-point halftime lead to 40-24 with 15:32 left.

South Florida eventually mounted one last comeback attempt. Jawanza Poland's 3-pointer with 1:44 left brought the Bulls within 47-41, but they got no closer.

For the second straight game, Jones missed much of the first half with foul trouble, but his absence wasn't missed like it was against Marshall.

In that game, West Virginia managed just 21 first-half points. On Sunday, West Virginia turned the tables on South Florida.

The Mountaineers got strong offensive rebounding to score several early baskets. Gilchrist kept South Florida close, but the Bulls went more than 10 minutes without a field goal and West Virginia took over.

Flowers' score with 2 minutes left in the half capped an 11-0 run and put the Mountaineers ahead 27-14. Mitchell had 10 points in the half.
