With 12 seconds left in regulation, Iowa State's Stephanie Kaphingst beat the Aggie defense to a cross from Elisa Berzins and headed the game winner past Kati Jo Spisak to upset No. 18 Texas A&M, 1-0, on Friday night at the Aggie Soccer Stadium.
With the loss, the Aggies fell to 8-3-1, 2-2 in Big 12 play, while the Cyclones improve to 8-3-3 on the season, 2-2-1 in the conference.
Throughout the first 45 minutes, A&M controlled the pace of the match, but went into the locker room scoreless. During the second half, the Aggies continued to press, taking six corners to Iowa State's one, and managed to fire-off eight shots.
For the match, A&M took 17 shots to the Cyclones' two. ISU goalkeeper Joanna Haig recorded 12 saves.
A&M's defense was solid throughout the 90 minutes of play, only allowing Iowa State to get close enough to send three shots at the goal, two of which were saves for Spisak.
"This is the biggest win in the history of our program, without a doubt," Iowa State head coach Rebecca Hornbacher said. "Our team never gave up, put forth an outstanding effort and we knew it would only take one goal to win the game. This is huge for our program and we believed from the moment the match started that we would win the game."
The Aggies return to action at 1:30 p.m. Sunday when they face the Nebraska Cornhuskers at the Aggie Soccer Stadium.
