Texas Tech pulled off a major upset Saturday, defeating top-ranked Arizona 78-75 in overtime at McKale Center. JT Toppin delivered a dominant performance with 31 points, 13 rebounds, and stellar passing that included the assist on Donovan Atwell's crucial overtime 3-pointer.

Toppin's 13-of-22 shooting and relentless energy proved too much for Arizona's defense to handle throughout the 45-minute battle. The 6-foot-9 forward showcased why he's a preseason All-America selection, playing all but 41 seconds and recording his 16th double-double of the season. His quick second jump and perfect positioning frustrated the Wildcats all game.

Christian Anderson added 19 points on six 3-pointers, while Atwell contributed 11 including two clutch shots in the final minute. The win marks Texas Tech's third consecutive victory and just the third time in school history they've beaten a No. 1 team. Coach Grant McCasland praised his team's preparation, noting their success comes from daily hard work rather than luck. The Red Raiders improve to 19-6 overall and 9-3 in Big 12 play, while Arizona suffers their first conference loss.
