Trevone Boykin completed 15 of 26 passes for 228 yards and two touchdowns and TCU's defense forced five turnovers to lead the Horned Frogs to a 48-17 victory Saturday against rival SMU.
Boykin overcame a 7 of 16 first-half performance by completing seven of his first nine passes in the second half, tossing touchdown passes of 20 and 56 yards to help the Horned Frogs (2-2, 0-1 in Big 12) overcome a 10-7 halftime deficit.
The Horned Frogs retain the Iron Skillet trophy for the second straight year, and they are 11-2 under coach Gary Patterson in the annual rivalry game.
SMU (1-3), which entered the game 10th in the nation in passing, amassed 292 yards of total offense, and quarterback Garrett Gilbert finished 23 of 44 for 276 yards and four interceptions. TCU also had six sacks, its most since 2009 at Virginia.
TCU played without star defensive lineman Devonte Fields, who was out with an unspecified injury.
