The Bears (9-16) used a four-run uprising off Husker starter Charlie Shirek, as Symons' double and a two-run single by John Ray provided all the offense that UNC needed to pull the upset.
In the sixth, the Bears loaded the bases on two walks and an infield single before Symons' double to right gave Northern Colorado a 3-1 lead. Luke Wertz came in for Shirek, but could not get out of the jam, as Ray sent a 2-1 pitch to center, scoring two more runs.
Ray, Grady Gorman and Seth Tartler all had two hits for UNC, which pounded out 12 hits and picked up its first win over NU since returning to the Division I ranks in 2004.
Shirek, who entered the game with a 1.23 ERA in five appearances, was tagged for five runs on eight hits to suffer his first collegiate defeat to fall to 1-1 on the year
Left-hander Chris Johns (4-3) earned the win by allowing two runs over 6.2 innings, while Tyler Pearson pitched 2.1 innings of scoreless relief for his first save.
The Huskers, who had won their previous 33 non-conference home games dating back to the 2004 season, had 10 hits, including three by Bryce Nimmo and two each from Ryan Wehrle and Luke Gorsett, but were done in going just 1-for-16 with runners in scoring position.
"We look at wins and big wins and tonight was a big loss," Nebraska Head Coach Mike Anderson said. "We did not perform well and everyone needs to be responsible. You have to give them credit as well. They performed well and should be proud of their kids."
The Huskers out to a 1-0 lead in the bottom of the first, as Nimmo led off
the inning with a double
and eventually scored on Wehrle's sacrifice fly. That would be the only lead of the night for NU, as Northern Colorado tied the score in the fourth with an RBI double by Zach Harris that plated Davin Warner and took the lead in the sixth.
The Huskers mounted a comeback in the sixth, as consecutive singles by Wehrle and Gorsett to open the inning put runners on first and second with no outs. An errant pickoff attempt by Johns moved Wehrle to third, where he scored on Brandon Buckman's ground out to first.
Nebraska threatened in both the seventh and the eighth, as they got the tying run the plate, but could not score off Pearson. In the seventh, a leadoff walk to Mort and a one-out single by Nimmo put runners on first and second, but Person retired the next two hitters to escape without damage.
One inning later, a Gorsett single and Buckman walk put two on with not outs, but Pearson wiggled out of the jam by getting pinch hitter Nick Sullivan to ground into a fielder's choice before striking out Jeff Christy and Jake Mort.
The Huskers return to action on Wednesday afternoon, as redshirt freshman Tim Radmacher makes his second career start. First pitch is set for 1:05 p.m. and
the game will be carried on Huskers.com.
