Texas Tech Beats Arizona 34-26 as Castellanos Sparks Big 12 and CFP Push
Tommy Castellanos made his first start and J'Koby Williams ran for 175 yards as Texas Tech held off Arizona 34-26, tightening the Big 12 race and boosting its playoff outlook before Tuesday's first CFP rankings.
Texas Tech answered its stumble at Cincinnati with a statement in Lubbock on Saturday, holding off Arizona 34-26 behind a quarterback change and a ground game that piled up 328 yards. Tommy Castellanos made his first start for the Red Raiders in place of Will Hammond, threw two touchdown passes and ran for 117 yards, while J’Koby Williams rushed for 175 yards, including a 64-yard touchdown with 2:05 left that sealed it.
The Red Raiders (7-1, 4-1 Big 12) entered as a top-15 team, and Arizona (6-2, 3-2) arrived ranked in the low 20s. The game was widely framed as a de facto elimination contest for both teams’ Big 12 title and College Football Playoff hopes. Texas Tech entered as a 4.5-point favorite, and the late Williams touchdown pushed the margin to eight.
Castellanos and Williams Flip the Script
Hammond was benched after the 37-24 loss at Cincinnati, and the switch to Castellanos gave the offense a different look. He finished 11 of 24 for 144 yards through the air and added the ground element, rushing 19 times for 117 yards and a score. It was his fifth career 100-yard rushing game and his first since his 2023 season at Boston College. His touchdown passes went to Terrance Carter Jr. from 24 yards out and to Kenny Johnson from 27 yards on fourth-and-2.
That Johnson touchdown put Texas Tech ahead for good, 24-23, late in the third quarter. The game featured three lead changes, and Arizona led 17-10 at halftime before Castellanos tied it with a 5-yard run early in the third. Arizona retook the lead on a 1-yard Kedrick Reescano run, but Ansel Nedore blocked the extra point, a one-point swing that mattered all the way to the finish.
From there, Texas Tech outscored the Wildcats 17-3. Stone Harrington added a 42-yard field goal early in the fourth, and Arizona then failed to capitalize on three chances to take the lead, turning the ball over on downs once and punting twice. Williams, who carried 14 times, broke a third-and-1 run for the clinching score and set a career high in rushing yards for the second time in three games. The win also tied a school record with a 13th consecutive home victory.
Big 12 Race Tightens Behind Utah
The result reshapes a crowded conference picture. Utah entered the weekend as the only unbeaten team in Big 12 play at 4-0, with BYU, Arizona, Oklahoma State and Texas Tech all sitting at 3-1. Texas Tech’s remaining schedule is West Virginia at home, then trips to Oklahoma State and Baylor, and a home finale against TCU. The Nov. 14 game in Stillwater looks like the next major swing game, since Oklahoma State is the only one of the top contenders the Red Raiders still face directly.
The first College Football Playoff rankings arrive Tuesday, Nov. 3, and Texas Tech now has a marquee win over a ranked conference opponent to put in front of the selection committee. The Big 12’s hopes of landing two teams in the 12-team field took a hit a week ago when both Texas Tech and BYU lost to unranked opponents, so the conference needs this kind of result to keep a second bid realistic.
What the Market Says About Texas Tech
Before the game, Texas Tech sat at +500 to win the Big 12 title, an implied probability of 16.7 percent, behind Utah at the top of the board and BYU, according to a midweek conference-title snapshot. The pre-game line was Texas Tech by 4.5 with a total of 55.5, and the Red Raiders were about -175 on the moneyline. Both teams entered 3-4 against the spread, so neither had been a reliable cover play. Texas Tech covered with the eight-point win. The 60 combined points cleared the posted total of 55.5, so the game finished over.
The bigger market story is the futures movement to watch this week. One simulation model that updated on Friday had Texas Tech’s playoff chances at 28 percent before kickoff, projecting that a win over Arizona would raise that to 44 percent and a loss would drop it to 3 percent. That is a heavy swing for one game, and it suggests the Big 12 and playoff futures on the Red Raiders should tighten after a result like this. The same model showed Texas Tech making the playoff in 92 percent of simulations at 11-1 but only 33 percent at 10-2, which frames how little margin for error remains. A second loss before December would likely push them back toward the bubble.
Utah remains the clear Big 12 favorite in most models, and the most common simulated title game outcome in one projection was Texas Tech against Utah in Arlington on Dec. 4. The Red Raiders’ next test is Saturday, Nov. 7, against West Virginia in Lubbock. Whether Castellanos keeps the starting job, and whether the run game keeps producing 300-plus yards, will drive how bettors and the committee view Texas Tech after Tuesday’s first rankings.
