San Diego State spent most of Sunday night chasing the damage from six early minutes. Texas Tech scored in the 13th and 18th minutes, then held off the Aztecs after Katie Senn converted a second-half penalty for a 2-1 victory in Lubbock.
Kylie Bahr supplied the first break at 12:11, finishing a pass from Eleanor Hays. SDSU nearly answered one minute later when Victoria Miller put an attempt on target, but Texas Tech goalkeeper Addie Todd made the save. The next Red Raider chance widened the separation: Kailey Carlen stopped Kaitlyn Giametta's shot at 17:14, and Taylor Zdrojewski finished the rebound before the Aztecs could clear it.
The sequence put San Diego State behind at halftime for the first time this season. It also forced the Aztecs to solve two problems at once after the break. They needed a cleaner route through Todd while protecting enough space behind the attack to prevent a third Texas Tech goal. The Red Raiders entered the match unbeaten and receiving votes in the national poll.
SDSU's best stretch began around the hour. Senn struck the crossbar late in the 63rd minute. When Bahr committed a foul in the penalty area just after the clock reached 70 minutes, Senn took the kick and drove it into the right side of the goal. The finish was her third of the season, a personal high, and made her the Aztecs' outright scoring leader.
The response continued immediately. Alexis Leath and Senn each forced Todd into saves during the next two minutes, turning a game that had been controlled by the early deficit into a one-goal contest with time left. Texas Tech did not concede again. SDSU's final recorded shot came before the 83rd minute, and the Red Raiders managed the closing stretch without another save required from Todd.
Carlen kept that margin from growing. Her stop against Zdrojewski in the 75th minute was her fifth of the night, a season high. The final totals favored Texas Tech 18-12 in shots and 7-5 in shots on goal. SDSU held a 6-4 edge in corners, but those additional restarts never produced the equalizer.
The result dropped the Aztecs to 3-2-1. One loss does not turn an uneven opening spell into a season pattern, yet Sunday gave SDSU a precise cost to review: two goals conceded before 18 minutes required nearly the entire remaining match to repair, and Senn's penalty only completed half of that job.
There was still useful evidence in the pursuit. SDSU put five attempts on frame against an unbeaten opponent, recovered enough control to earn more corners and created consecutive chances after scoring. The distinction is timing. Those actions arrived after Texas Tech had the lead and could defend it; the Red Raiders' decisive work was already complete before the match settled.
San Diego State now gets six days before visiting Utah Valley on Saturday at 6 p.m. Pacific, the final road match of its nonconference schedule. The next assignment is less about generating urgency than applying it sooner. In Lubbock, the Aztecs found a way back into the game, but the opening two concessions left no room for one last missed connection.
