It took over 80 minutes, but Theresa Knutson finally ended the suspense with her snap shot from the left side past KM Glacier goalie Jenna Bales at the 5:43 mark to give top-ranked Onalaska a 5-4 win in semi-final action Friday afternoon at the Alliant Energy Center.

The first period was scoreless with Ona holding a 6-4 shot edge.

KM scored first at the 3:27 mark when Jessica Foley knocked in a power play goal, with an assist to Irene Hougard.

It took Onalaska 25 seconds to tie the contest when Knutson tallied with a helper from Molly Coughlin.

Knutson scored again at the 7:06 mark when she got behind the defense with a nice toe-drag and beat Bales to increase the lead to 2-1. Baylee Darling and Ellie Meyer earned assists on the play.

The 'Toppers added to their lead about three minutes later with a Kianna Kalmes score. The puck was shot on net and it hit off a skate in front and bounced in to make it 3-1. Knutson got an assist on the play.

The period ended with Onalaska holding an 11-6 shot advantage.

Just over three minutes into the third, freshman Jacyn Reeves used great individual effort while on the PK to score a shorty for Ona. She grabbed the puck behind the net after Bales and a defenseman had a miscommunication with a dumped-in puck. Reeves skated out in front of the net and ripped a shot that caught the upper left corner of the net to make it 4-1.

The Glacier would then reel off three goals in six and one-half minutes to tie the contest.

Jeralyse Tylke scored at 4:46 with an assist to Jamie Ertl to make it 4-2.

Just over a minute later, Morgan Hollowell scored from the top of the circle to cut it to 4-3.

Then she tied the game at the 11:15 mark when her shot from the left circle beat Ona goalie Jeanalyn Schindler on the stick side.

Onalaska held a 13-10 shot edge in a wild third period.

In the three scoreless extra periods, Onalaska outshot KM, 19-11. 

The fourth overtime saw Knutson finally end the game with her shot from the left side.

Schindler stopped 28 shots despite getting shaken up when a KM Glacier player ran over her on a breakaway. Bales ended the game with 47 saves in a valiant effort.

Onalaska (26-2) moves on to Saturday's championship game against the Central Wisconsin Storm at noon. Kettle Moraine ends their season at 20-7.
