Red-shirt freshman quarterback Foster Sawyer, who started in place of an injured Trevone Boykin, threw for 105 yards in the half, but was picked off twice.
The Frogs opened the scoring early when Sawyer found wide receiver Kolby Listenbee for a 37 yard touchdown pass to give TCU a 7-0 lead.
That would be all for the Frogs’ offense in the half, as the Sooners stormed back to score 23 unanswered points.
Oklahoma quarterback Baker Mayfield found wide receiver Sterling Shepard for a 21 yard touchdown pass late in the first quarter to tie the game at 7-7. The Sooners then shutout the Frogs 16-0 in the second quarter.
After taking a 13-7 lead on a pair field goals early in the quarter, Mayfield found wide receiver Dede Westbrook for a 36 yard touchdown pass with 5:06 to play in the half to give Oklahoma a 20-7. The Sooners then tacked on a 37 yard field as time expired in the half to take a 23-7 lead over the Frogs.
The Frogs were out-possessed 11:38 to 3:22 by the Sooners in the half.
