FORT WORTH, Texas (AP) - Amric Fields had 12 points and a big part in an upset-sealing run as last-place TCU beat No. 21 Oklahoma State 70-55 on Saturday after the Cowboys had won three consecutive Big 12 games against ranked teams.
The Horned Frogs (15-10, 2-10 Big 12) used a pair of 10-0 runs in the second half, the latter spurt coming in the closing 4 minutes to clinch the victory.
Oklahoma State (17-8, 7-6) was within 56-53 when Anthony Hickey found a wide-open gap and drove for a layup high off the glass with 4:52 left. The Cowboys then went nearly 3 1/2 minutes without scoring.
Fields started the run with two free throws and later had an acrobatic driving layup to make it 64-53 with 1:38 left.
