The men played a strong offensive game despite pouring rain throughout the non-conference match, and the 5-0 win brought the Oles to a 6-5-0 season record (3-2-0 MIAC).
St. Olaf was only winning by one goal at halftime, when Swenson scored with less than five minutes to go in the first half.
Swenson scored another unassisted goal early in the second half, which was quickly followed by Langholz's two goals - scored only four minutes apart. Midfielders Phil Kennedy '10 and Matt Yak '11 each assisted a Langholz goal.
Bobby Anderson '08, a mainstay of the team's defense, also scored just before the end of the game by heading the ball past the Eagles' goalie. St. Olaf attempted a total of 29 shots for the game, compared to only 11 for Northwestern. Goalie Kevin Friede '09 saved all four of the Eagles' on-target shots.
The game against Northwestern followed another stellar performance by the Oles Saturday at St. John's, where they won 4-1 against the team that tied for the MIAC regular-season title last year.
John Zietlow '11 led the Oles to victory with two goals, scored in a six-minute span in the last ten minutes of the game. Barrett Kennedy '09 and Swenson also scored goals earlier in the game.
In an unusual turn of events, two of the team's four goals were scored off penalty kicks. Early in the first half, forward Scott Crider '10 was inside the box on a breakaway when he was fouled by the Johnnie's goalkeeper. Kennedy scored off the resulting penalty kick.
One of Zietlow's goals also came off a penalty kick, after Langholz was fouled in similar fashion. St. John's only scored once, with an unassisted goal in the 52nd minute.
"Our offensive attack is coming along. Scoring nine goals in two games is something we haven't done in the last couple years, especially against a team like St. John's," said Anderson, one of the St. Olaf captains.
The conference game against St. John's brought the Oles' MIAC record to 3-2-0, bringing them to fifth place in the standings. However, St. Olaf is tied with current MIAC leader Carleton for first in number of conference goals, at 10 for each team. With five goals each in conference games, Swenson and Zietlow are tied for third among individual players in the MIAC for goals.
The Oles head to Iowa this weekend for a pair of nonconference games.
"We're playing one of the top teams in the country Saturday. We get to see how we match up and how we've improved over the course of the season against some nonconference opponents," Anderson said.
The Oles play Loras College, current IIAC leaders, on Saturday, then head to Cedar Rapids to play Coe College on Sunday.
The team resumes MIAC play Wednesday against Bethel, the first of five remaining conference showdowns.
