After 97 minutes of play Sunday afternoon, what was most frustrating for Kansas University’s soccer team was not that it lost, but instead how it lost.

With a few costly miscues on the defensive end, No. 23 Kansas spoiled an otherwise strong effort against No. 25 Wisconsin, falling, 3-2, in overtime after putting in a game-ending own-goal.

“You look at the goals they scored … each goal was from a mistake that we made,” Kansas coach Mark Francis said. “They were good enough to punish us. We just have to quit making mistakes in the back.”

The final goal was a combination of misjudgment and misfortune, leaving both the Jayhawks and the 1,273 fans attending in stunned silence afterward.

In the seventh minute of overtime, Kansas defender Nikki Alvarez had a chance to clear the ball back into the Wisconsin zone, but instead tried to control the ball and had it stolen away.

With a run at the goal, Wisconsin’s Amy Vermeulen fired a shot that was partially deflected by Kansas keeper Colleen Quinn.

The ball bounded toward the goal, with Jayhawks Afton Sauer and Michelle Rasmussen giving chase.

While trying to control and quickly clear the ball, Sauer instead redirected it backward into her own net as a helpless Quinn watched.

“I just didn’t get enough of it,” Sauer said. “Michelle tried to come in and play it off the line. We both just tried to get there and couldn’t clear it out. It was just really unlucky.”

Wisconsin scored three goals despite attempting only 12 shots.

Kansas finished with 15 shots, six on goal.

“I felt like we gave them the opportunities to score, and they took the opportunities,” Francis said. “You have to give them credit for finishing the chances they had. If we could eliminate some of those mistakes, it’ll be a lot tougher to score on us. We haven’t given up three goals in a long time.”

The Jayhawks did it only once last season, allowing three scores in a double-overtime loss to No. 21 Texas. Kansas gave up just 13 goals in 23 games last season with graduated keeper Meghan Miller in net.

Caroline Smith opened the scoring for Kansas in the 11th minute, taking a cross from Holly Gault and redirecting it off the keeper and then the post for a 1-0 Jayhawk lead.

Katy Lindenmuth connected on consecutive goals to give Wisconsin the lead, but Alvarez gave the Jayhawks a much-needed score and momentum in the 51st minute.

After a steal, the defender pressed upfield looking to find Smith.

With two players guarding Smith, Alvarez decided at the last moment to launch a shot herself from the edge of the penalty box.

The ball squirted its way under the right arm of goalie Lynn Murray for Alvarez’s second career score.

“After I scored that goal, all the girls went crazy,” Alvarez said. “I was so excited, and my teammates were excited. I think we kind of got the momentum back for a while.”

Kansas fell to 0-1-1.

The Jayhawks will look to pick up their first victory — and reverse their fortunes — Wednesday at home against Missouri State.

“I don’t think (Vermeulen) could ever do it again, that’s for sure,” Alvarez said. “It’s very unlucky for teammates to work for 90 minutes plus and have to lose on a goal like that.”
