So much for Colorado College’s Saturday-night magic.

CC ran out of tricks in its series finale against Minnesota Duluth, surrendering five second-period goals and dropping a 7-4 decision at the World Arena.

It was the first defeat this season on a Saturday for the Tigers, who fell to 9-5-4 overall and 6-4-2 in WCHA play.

They showed some spark early, holding leads of 2-0 and 3-2 before the roof caved in. Already playing without injured regulars Jake Gannon, Scott McCulloch and Tim Hall, they lost sophomore defenseman Ryan Lowery to a checking-from-behind major and game misconduct midway through the middle frame.

The Bulldogs capitalized on a 5-on-3 manpower advantage to tie the game just 20 seconds after the penalty, then struck twice more in the period – including a shorthanded tally that proved to be the game winner – to take command.

Stephen Schultz and Chad Rau factored in on three goals apiece for Colorado College, Schultz scoring twice while Rau and freshman defenseman Gabe Guentzel each added a red lighter.

Minnesota Duluth, which improved to 7-4-5 overall and 4-4-4 in league play, got a pair of tallies from Jordan Fulton and a goal and two assists by Justin Fontaine, the wingers on UMD’s second line. MacGregor Sharp scored the unassisted go-ahead goal at 16:28 of the second period and set up Nick Kemp’s shorthanded effort just 1:27 later.

Colorado College slipped from second to fourth place in the WCHA despite out-shooting the Bulldogs by a 43-30 margin. Richard Bachman was victimized for all five Duluth goals in the second period before giving way to Drew O’Connell for the final 20 minutes. Alex Stalock finished with 39 saves for the visitors.
