No. 13 Texas Tech defeated No. 22 Arizona 34-26 on Saturday, with first-time starting quarterback Thomas Castellanos providing a dual-threat spark that revitalized the Red Raiders' offense.
Coach Joey McGuire benched Will Hammond in favor of Castellanos, a senior who joined the roster via a late injunction. Castellanos completed 11 of 24 passes for 144 yards and two touchdowns while adding 117 rushing yards and a score on the ground, becoming the first Texas Tech quarterback to rush for 100 yards since Tyler Shough.
The running game flourished behind Castellanos' threat, as J'Koby Williams exploded for 175 yards and a touchdown, including a decisive 64-yard scoring run in the fourth quarter. Texas Tech totaled 328 rushing yards, the most allowed by an Arizona defense since 2020.
Arizona had won five straight and averaged 28 points per game since a loss to BYU, but surrendered 34 points, their most since September 2025.
Castellanos' eligibility remains on a temporary injunction, and his passing accuracy (45.8% completion) is below his career average. Nevertheless, his presence re-inserts Texas Tech into the Big 12 championship race heading into the final stretch of the season.
