After a mostly uneventful first half, Lavrusky turned the tides with a stunning goal in the final 30 seconds of the half. Stewart sent a pass to Lavrusky near the right sideline, and Lavrusky dribbled up center and lofted a shot from about 25 yards out over the San Diego State goalkeeper Melanie Vaughn to give UCLA the 1-0 halftime lead.
"We wanted to score earlier and put them on their heels even more, and we didn't do that, so it was a good thing that we scored just before the half to set the tone coming out in the second half," said UCLA head coach Amanda Cromwell.
UCLA came up firing in the start of the second half, but Vaughn made big saves on a pair of Sarah Killion shots to keep the Bruins off the board. Vaughn finished the game with seven saves.
The Bruins scored on a set piece in the 85th minute. Caprice Dydasco's corner kick hit the crossbar, and Dahlkemper hammered home the rebound to the lower right corner for a 2-0 lead.
"We've been working on corners a lot and haven't been real effective on scoring on them, so that was one of our goals - getting a goal on a set play," said Cromwell.
UCLA continued to pepper the Aztecs with shots, with Vaughn making two saves on shots by Lavrusky and another on a shot by Taylor Smith. UCLA outshot San Diego State, 24-6 and had a 9-2 advantage on shots on goal. Bruin goalkeeper Katelyn Rowland made two saves and recorded her third shutout of the year.
The Bruins will stay in Los Angeles next week with road games at Pepperdine on Sept. 20 and at Loyola Marymount on Sept. 22.
