Fort Worth, TX (SportsNetwork.com) - Trevone Boykin failed to stick the landing on a somersault into the end zone, but it was an otherwise flawless performance for the TCU quarterback on Saturday.

Boykin accounted for 342 yards and four touchdowns and No. 6 TCU made its national title case by routing No. 9 Kansas State, 41-20, in a Big 12 showdown.

What was billed as an elimination game for the inaugural college football playoff turned into a one-sided affair, with the Horned Frogs (8-1, 5-1 Big 12) gashing the Wildcats' vaunted defense for 553 yards.

Boykin did most of the damage with 219 yards and a TD on 23-of-34 passing while adding 123 yards and three scores on the ground, including an acrobatic run early in the third quarter that ended with him being flipped into the end zone.

Aaron Green ran for 171 yards and a touchdown for TCU, which forced a three- way tie atop the conference. The Horned Frogs will be heavy favorites against Kansas, Texas and Iowa State the rest of the way and will likely move up to No. 5 in the playoff rankings thanks to Auburn's loss earlier Saturday.

Jake Waters threw for 291 yards with two touchdowns and an interception for Kansas State (7-2, 5-1), which had allowed just 17 points per game during its five-game winning streak coming in.
