Baker scored first in the contest on a goal from senior leader Ben Coyle, the Olathe, Kan., native received a ball that was perfectly placed by Robert Hoeven and he blasted it home past Chris Ericksson.
MNU responded with a score from Lippi Souza just one minute later to tie things up.
Baker took just 10 shots in the match, while MNU attempted 15. Matt Bickley had three saves and Ericksson collected one.
This marks the first loss for the Wildcats since a Sept. 8 loss at NCAA Division I McKendree, 2-0. It also marks the first goals given up since Sept. 21 when they gave up a goal to Kansas Wesleyan.
The Wildcats will take on their second ranked opponent on the week this Saturday, Oct. 12 at 7:30 p.m., as they face No. 7 ranked Benedictine.
