Fort Worth, TX (SportsNetwork.com) - Trevone Boykin threw for four touchdowns and caught a pass for a score, powering fourth-ranked TCU to a share of the Big 12 title with a 55-3 rout of Iowa State.
The Horned Frogs entered the game third in the College Football Playoff rankings and are hopeful Saturday's effort will impress the selection committee enough to keep them in the exclusive four-team field, which will be announced Sunday.
Boykin was 30-of-41 for 460 yards and added 44 yards on eight carries.
Aaron Green rushed for 104 yards and a score and also caught a touchdown pass for TCU (11-1, 8-1 Big 12), which will be co-conference champions with Baylor -- the only team to defeat the Horned Frogs this season.
Sam B. Richardson completed only 16-of-40 passes for 152 yards and one interception for the Cyclones (2-10, 0-9), who concluded the season with six consecutive losses.
The Horned Frogs opened the scoring on a trick play. Boykin threw a backward pass to the left side of the field to wide receiver David Porter, who fired back across to the TCU quarterback. Boykin then followed a convoy of blockers as he raced down the right sideline for a 55-yard touchdown 5 1/2 minutes in.
TCU marched 86 yards in 12 plays on its next possession and went up 14-0 on Green's 3-yard touchdown run.
The Cyclones were in the red zone at the outset of the second quarter, but wound up settling for a 26-yard Cole Netten field goal after Ben Boesen dropped a pass in the end zone.
Boykin later completed a 49-yard pass to Kolby Listenbee to set up Jaden Oberkrom's 39-yard field goal.
Iowa State then failed to capitalize on a TCU miscue. The Cyclones had the ball at the TCU 39 following a muffed punt, but turned it over on the next play. Unlike the Horned Frogs, they were unsuccessful on a trick play, as Ranthony Texada picked off an underthrown pass from wideout Jarvis West.
TCU looked to extend its lead before halftime, but Boykin was intercepted by Sam E. Richardson in the end zone.
"We knew we had to make a statement, but we started slow," said TCU head coach Gary Patterson. "Defensively, we were playing all day. Offensively, we hurt ourselves and we still had almost 500 yards at halftime. We just didn't get in the end zone. We came out in the second half and started to do some things."
The Horned Frogs broke the game open in the third quarter by scoring 31 points.
Green caught a pass in the flat on 3rd-and-3 and sprinted 54 yards to the end zone on the opening drive of the second half. Oberkrom made a 23-yard field goal, Derrick Kindred scored on a 44-yard return after picking off Sam B. Richardson and Boykin threw touchdown passes of 18 and 45 yards to Josh Doctson and Deante' Gray, respectively.
Boykin capped his glittering performance with a 14-yard TD pass to Ja'Juan Story early in the fourth quarter.
"We were pesky for 30 minutes," said Iowa State head coach Paul Rhoads. "I was pleased with the effort and the response of our guys in the first 30 minutes. We were worn out for that 30-minute effort and I think that showed quickly in the second half."
Boykin established a single-season school record with 30 touchdown passes. He broke the previous mark of 27 set by Andy Dalton in 2010 ... TCU has forced at least one turnover in 24 straight games ... Iowa State has lost 12 straight games against ranked opponents since a 37-23 win at then-No. 15 TCU on Oct. 6, 2012 .. Doctson had 151 yards on nine receptions.
