LUBBOCK, Texas (AP) - Brock Purdy threw for 378 yards and three touchdowns, freshman Breece Hall ran 75 yards for the first of his two scores and Iowa State took a big lead early in a 34-24 victory against Texas Tech on Saturday.
Purdy had 277 yards and all three of his scoring tosses for a 20-0 lead early in the second quarter, with two TDs to tight end Charlie Kolar, as the Cyclones (5-2, 3-1 Big 12) won their third straight game since losing at Baylor in their only other scheduled trip to Texas.
The Red Raiders (3-4, 1-3) extended their longest losing streak in the series with Iowa State to four, dropping their second in a row this season since beating Oklahoma State for the best victory so far under first-year coach Matt Wells.
Purdy was 15 of 17 and had the ball again in the second quarter with the 20-point lead when he threw three straight incompletions. The Red Raiders answered with a 6-yard TD run by SoRodorick Thompson, who scored twice.
Texas Tech opened the second half with a field goal to get within 20-10 before Hall's long scoring run on the next play.
Hall added a punctuating 30-yard TD in the fourth quarter and finished with 183 yards rushing, his season high for the second straight week after going for 132 yards with three touchdowns in a 38-14 win over West Virginia.
Jett Duffey, coming off the first consecutive 350-plus-yard passing games for Texas Tech since Patrick Mahomes in 2016, was 40 of 52 for 239 yards with a mostly meaningless touchdown late.
Purdy had quite a stretch of slightly more than two quarters in Texas, from the rally he engineered late in the 23-21 loss to Baylor to the first quarter-plus against the Red Raiders. The sophomore completed 27 of 33 passes for 456 yards with five TDs in that stretch.
Iowa State: The game played out in an eerily similar way to the Cyclones' loss at Baylor. But the teams were reversed. This time Iowa State went up 20-0 instead of falling behind by the same score, then let Texas Tech back in the game the same way Baylor gave the Cyclones a chance three weeks ago. But Tech never got closer than 10.
Texas Tech: Iowa State missed a chance to put the game just about out of reach in the first half with two stalled drives that ended in missed field goals by Brayden Narveson. But the Red Raiders had an even bigger miss when Trey Wolff was wide right from 42 yards with 11:43 left in the game and Texas Tech down 10.
