DE PERE - St. Norbert College junior forward Michael Spethmann's goal 56 seconds into overtime lifted the Green Knights to a 4-3 win over St. Olaf College in a first-round NCAA Division III Tournament game at Cornerstone Community Center.

The Green Knights (24-6) advance to a national quarterfinal at 7 p.m. Saturday, March 19 at Augsburg University in Minneapolis. St. Norbert has met Augsburg in national quarterfinals in 2016, 2017, 2018 and 2019, with all four of those meetings St. Norbert wins at the Cornerstone Community Center.

St. Norbert rallied from deficits of 2-0 and 3-1 to keep its season alive. The Green Knights wasted little time in overtime, with Chase Mickelson's neutral-zone pass to Peter Bates redirected by Bates' skate to an open Spethmann at the blue line. Spethmann than outraced a St. Olaf defenseman to the goal, beating Oles goaltender Lukas Haugan five-hole to set off a wild celebration.

The overtime win is St. Norbert's fourth of the season, improving to 4-0 in overtime games this season - tying a school record set in 2007-08 for overtime wins in a season. It is also the fifth-straight NCAA Tournament appearance where the Green Knights have won an overtime game. St. Norbert is 6-3-1 all-time in overtime games in the NCAA Tournament.

St. Norbert had to overcome a slow start as St. Olaf (11-15-3), the first team to ever qualify for the NCAA Division III Tournament with a below-.500 record, scored twice in the first 12 minutes to take a 2-0 lead. Tyler Cooper's shot just 1:55 into the game ricocheted off St. Norbert goaltender Colby Entz's shoulder up into the air and came down behind him into the net for a 1-0 lead. The Oles added to their lead when Parker Casey scored at 11:54. The Green Knights would cut into the deficit when Evan Cholak scored on a wraparound at 14:18 for his fourth goal of the season. St. Olaf outshot St. Norbert 16-14 in the first period.

The Green Knights dominated play in the second period, outshooting the Oles 16-5, but a turnover deep in the St. Norbert defensive zone led to a Jonathan Young goal at 16:25 for a 3-1 edge.

St. Norbert got back into the game when Liam Fraser poked home a loose puck laying out front at 4:14 of the third period. St. Norbert would get its first two power plays of the game at 4:48 and 10:36, but did not convert on either. However, as the second power play expired the puck was played by a St. Olaf player coming off the bench before the Ole in the penalty box could get off the ice, resulting in a too-many-men penalty. St. Norbert capitalized quickly, with Brendan Mark's shot through traffic just eight seconds into the man advantage knotted the game at 3-3 at 12:47. The Green Knights outshot the Oles 19-4 in the third period.

Bates finished with two assists for the only multi-point game for St. Norbert, while Cooper and Csaey each had a goal and an assist for two-point games for St. Olaf.

St. Norbert outshot St. Olaf 51-26. Entz made 23 stops for the Green Knights, while Haugen made 47 saves for the Oles.

St. Norbert was 1-for-3 on the power play, while St. Olaf was 0-for-1.

The Green Knights have now won 24 of their last 29 NCAA Tournament games. The win was St. Norbert's 33rd all-time in the NCAA Tournament, one short of Middlebury College's 34 for most all-time in tournament history.
