Too many penalties against a hard-charging National Collegiate Hockey Conference foe proved too much for Colorado College.

As a result, visiting Minnesota-Duluth pulled away for a 5-1 victory and an NCHC series split before 6,382 fans at World Arena on Saturday.

Tigers coach Scott Owens was quick to credit the No. 20-ranked Bulldogs and use an emotional pregame ceremony honoring the late Scott Winkler as an excuse for Duluth's dominant performance.

"Duluth came out focused and dialed in and they kept that up from the start to the end." Owens said. "It just shows you how tough it is to get a sweep."

Duluth (2-1-1, 1-1) put away the Tigers in the third period on a power-play goal 50 seconds into the final frame by Justin Crandall, his second of the game, and another by rookie Alex Iafallo, his first for UMD. UMD made it 5-1 on an unassisted breakaway by Kyle Osterberg.

"It was really good to get a power-play goal and to get it early in the third," UMD coach Scott Sandelin said. "That was probably our best game so far."

The result marred a strong performance by senior goalie Josh Thorimbert, who kept CC (1-1, 1-1) in the game through the first two periods with 27 saves, three less than he made in Friday's 3-1 victory. He finished with 39 Saturday.

"I feel sorry for Josh," Owens said. "They played with desperation and had us on our heels."

UMD outshot CC by a 44-14 margin, including a 29-9 edge through two periods. That advantage was aided by 11 penalties against the Tigers, including two five-minute calls.

Working off 17:17 on the penalty kill wore down the Tigers, who were down to four defensemen after freshman Gustav Olofsson suffered an upper-body injury during the second period and Ian Young received a game misconduct late in that frame.

But thanks to pretty stickhandling by freshman defenseman Jaccob Slavin, the Tigers trailed by only a 2-1 margin entering the third period.

Slavin and senior Archie Skalbeck completed a give-and-go in the Bulldogs' zone. The rookie then skated from faceoff circle to circle, stickhandling his way past two defenders before firing a rising shot that beat UMD senior goalie Aaron Crandall high stick side with 3:24 left in the second period. It was Slavin's first goal as a Tiger after picking up an assist on Friday.

UMD took a 2-0 lead with 8:00 left in the second on a goal by Justin Crandall, whose shot went in off a Tiger.

Bulldog freshman left wing Alex Iafallo scored off a crossing pass from junior Caleb Herbert that Thorimbert had no chance on for a 1-0 lead late in the first period.
