The gritty goal followed a couple of highlight reel goals in the first half from senior Haley Rosen and sophomore Andi Sullivan and kept the Cardinal (3-0, 9-2) undefeated in Pac-12 play.

The ball bounced off a couple Arizona defenders before finding the left foot of Carusa, who knocked it into the back of the net for the game-winner as Stanford posted a 3-2 triumph.

Stanford earned its ninth corner kick of the game early in the second overtime period. After the initial service went through the box, Stephanie Amack received the ball and sent a second cross into the 6-yard box.

Redshirt freshman Kyra Carusa knew exactly what to do when she found the ball at her feet in a crowd in front of the net. The result was yet another dramatic overtime victory for the fifth-ranked Stanford women's soccer team.

Stanford increased its pressure and controlled the pace of play in the second half but could not expand on its lead.

Sullivan followed Rosen with a terrific goal of her own in the 31st minute, taking space in the midfield and unleashing a blistering right-footed shot that hit the inside of the left post before going in the back of the net.

The Cardinal responded just over two minutes later when Rosen found space in the midfield and fired a perfect left-footed shot to the left side netting to tie the score.

Despite the advantages, Stanford found itself in an early hole. Arizona got on the board first when Paige DeGracie deflected a shot by Paige Crouch in front of the goal to put the Wildcats up, 1-0.

After a scoreless first overtime period, Carusa broke through for the Cardinal, which is 3-0 in overtime games this year and remained unbeaten in its last 11 extra-period games.

Stanford continued to pressure the remainder of the second half but could not find the go-ahead score and went to overtime for the third time this season.

The Cardinal was outshooting the Wildcats 9-1 until Gabi Stoian found space in the middle of the field from about 20-yards out and sent a shot to the lower-left corner of the goal to knot the game at 2.

"I thought it was a thrilling game of soccer," Gunn said. "Probably both coaches would want to tighten up defensively, but you couldn't get a more exciting game to watch and be a part of. It's a credit to both teams and in the end I felt that our resiliency paid off.

The senior captain converted and is four-for-four in his career from the spot. It was Vincent's second goal of the season, the ninth of his career, and his eighth in Stanford's last 25 matches. He began his Cardinal career with one goal in his first 41 games.

Four minutes later, Langsdorf played Baird, who slid the ball Eric Verso, but his shot rang off the near post.

Langsdorf's strike capped off a frenetic first 20 minutes of play. In the third minute, Stanford's Andrew Epstein made a sensational save on Cal's Jose Carrera-Garcia from the edge of the six-yard box.

"That was great attacking play and a good combination by the strikers," Cardinal coach Jeremy Gunn said. "It's what we look to do, was a wonderful play by both and another emphatic finish."

Corey Baird, who started up top to fill the void left by Jordan Morris, played a through ball to Langsdorf. The sophomore was able to get his left foot on the ball before absorbing a Cal tackle and his shot beat an advancing Alex Mangels to the keeper's left. The goal, Langsdorf's third of the year, put Stanford on top, 2-0.

In the 18th minute, the Cardinal took possession in the midfield, turned and put together its attack.

Stanford (8-1-0, 1-0-0), 14-1-4 in its last 19 games at Cagan Stadium, returns home to host No. 15 Washington on Friday in a game televised on the Pac-12 Networks.

The win upped Stanford's win streak to eight, the program's longest since 2001, and moved the Cardinal to 3-0-1 in its last four matches against the Golden Bears (5-3-0, 0-1-0).

Stanford keeps rolling. Brandon Vincent converted a first-half penalty, Foster Langsdorf scored on the counter three minutes later and the No. 3 Cardinal opened its Pac-12 schedule with a 2-1 win at rival California on Sunday.
