FORT WORTH, Texas (AP) — Trevone Boykin passed for a career-high 460 yards and caught a touchdown pass as No. 4 TCU earned at least a share of the Big 12 championship and did nothing to hurt its case to be included in the College Football Playoff with a 55-3 victory against lowly Iowa State on Saturday.

The Horned Frogs (11-1, 8-1 Big 12) came into championship weekend ranked third in the selection committee’s rankings. TCU was the only playoff contender not playing a ranked team this weekend. There wasn’t much the Frogs could do help themselves against the Cyclones (2-10, 0-9), but they avoided the type of clunker that could have caused the committee to downgrade them.

Iowa State finished winless in the Big 12 for the first time since 2008, and the first time under sixth-year coach Paul Rhoads.
