Weissbach scored a pretty one with his first shot on goal in a Badgers uniform, taking the puck in the left circle and quickly ringing a short-side shot bar-down to put Wisconsin ahead 2-0 at 10:55 of the opening frame.
He connected again at 14:48 of the middle period when he filled a lane on a two-on-one rush and one-timed a beautiful saucer pass from Ryan Wagner to make it a 3-1 game.
Weissbach, who paced the USHL's Tri-City Storm a year with 19 goals and 47 points, will look to maintain the hot hand Friday when the Badgers begin Big Ten Hockey conference play with a home set against Ohio State.
Prince Albert defenseman Vojtech Budik (2016, fifth round) jumped up into the play Friday and scored the overtime goal to thrust Prince Albert to a 6-5 victory over Calgary.
The marker, Budik's first of the year, was his fifth career goal in 129 Western Hockey League games, and his second-ever game-winner. It's the first overtime goal of his career.
Budik got back to work Saturday, sending a feed from the left point straight to the goal mouth for a primary assist as the Raiders defeated Medicine Hat 4-2. Budik, who rounded out the evening with a plus-3 rating, has a goal and an assist through four games.
In Friday action, Brandon Hagel (2016, sixth round) picked up an assist to extend his point streak to three games as Red Deer got past Brandon 5-4.
Hagel was kept off the score sheet Saturday in the Rebels' 4-2 loss to Moose Jaw, but got back on track with a helper Sunday in a 6-1 loss to Regina.
Hagel has gotten on the score sheet in four of five games played to total three goals and seven points.
Cliff Pu (2016, third round) notched a pair of second-period helpers Sunday as London erased a two-goal deficit and held a brief lead, but ultimately fell to Oshawa 5-4.
Pu, who began the week with four shots on goal and a minus-1 rating in Friday's 5-0 loss to Kingston for the Knights' first shutout defeat since Dec. 5, 2014, has collected four assists through his first four games of the season.
Defenseman Austin Osmanski (2016, seventh round) logged a minus-1 rating with one shot on goal Friday as Mississauga lost to Hamilton 2-0.
The next night, Osmanski punched one shot on net as the Steelheads were bested by Owen Sound 6-4.
Osmanski has one assist and seven shots on goal through his first four games.
Shawnigan forward Vasily Glotov (2016, seventh round) was kept off the score sheet Wednesday in 3-2 loss to Sherbrooke.
Glotov was blanked Friday as the Cataractes fell 3-1 to Quebec, and was again silenced in Sunday's 6-2 loss to Rimouski.
After netting two assists in the first period on opening night, Glotov has gone four consecutive games without a point.
In Sunday exhibition action, Casey Mittelstadt (2017, first round) showed off his stickhandling skill with a dominating shift that resulted in a backhand goal at 5:53 of the opening frame and later added a trio of third-period helpers as No. 3 Minnesota downed the University of Alberta 6-2.
Projected to remain hot coming off a four-point game, Mittelstadt will be an integral part of the high-powered Gophers' attack when regular season play kicks off Friday versus host No. 6 Minnesota-Duluth at the 2017 IceBreaker.
While Mittlestadt looks to make an immediate impact, Minnesota will be without the services of forward Connor Hurley (2013, second round) for the entire season. Hurley produced 14 goals and 48 points over the previous three seasons with Notre Dame, but will sit out the entire 2017-18 season due to NCAA transfer regulations.
Christopher Brown (2014, sixth round) notched two assists and a plus-2 rating Saturday while serving as the top-line centerman as No. 13 Boston College got past New Brunswick 4-2.
Boston College defenseman Casey Fitzgerald (2016, third round) played to an even rating in Saturday's win over New Brunswick. The Eagles gets the season going Friday versus Quinnipiac.
Senior forward Judd Peterson (2012, seventh round) opened the preseason playing the center position, registering four shots on goal as No. 9 St. Cloud State steamrolled Regina 8-1.
Third-year defenseman William Borgen (2015, fourth round) registered one shot on goal for St. Cloud State, who kicks off the regular season Saturday at Minnesota State.
Philip Nyberg (2016, fifth round) produced one shot on goal as Connecticut defeated St. Francis Xavier 2-1. UConn heads north this weekend to begin the Hockey East conference schedule Friday at Maine.
Junior defender Ivan Chukarov (2015, seventh round) sat out Saturday as Massachusetts blanked Queens University 1-0. The Minutemen launch the regular season schedule Friday against Arizona State.
Brett Murray (2016, fourth round) did not play Sunday as No. 10 Penn State dropped a 4-3 overtime decision to the University of Ottawa. Next up for Penn State is Friday's season opener at Clarkson.
Providence College defenseman Jacob Bryson (2017, fourth round) was a pleasant surprise last season, finishing third among Hockey East freshmen defensemen with 20 points, and sixth among all NCAA freshman defenders with 17 helpers. The Friars, who did not play last week, will begin the season on the road Friday at Miami.
Also among the idle last week was senior forward Maxwell Willman (2014, fifth round), who will play a featured role for Brown University this season following his 2016-17 breakout campaign that saw him pot 11 goals and 26 points. The Bears don't begin their season until Friday, Oct. 28 when they visit Yale.
Rasmus Asplund (2016, second round) scored his third goal of the year into an empty net Saturday as Färjestad BK defeated Mora IK 5-2.
The team rematched Sunday with Asplund seeing his four-game point streak snapped as Färjestad earned the weekend sweep with a 4-1 win.
Victor Olofsson (2014, seventh round) recorded one shot on goal in 17:33 of work Saturday as Frölunda HC fell to the Växjö Lakers 3-1. Olofsson has a goal and an assist through four contests.
Also from Saturday, Marcus Davidsson (2017, second round) posted one shot on goal and won four of nine face-offs in 7:46 of work as Djurgården IF doubled Skellefteå AIK 4-2.
Ukka-Pekka Luukkonen (2017, second round) earned the start for LeKi in Friday's Mestis season opener, stopping 27 of 29 shots to backstop a 4-2 victory over Peliitat. The calm, poised 18-year-old netminder is expected to play a lot of minutes this season in Finland's second professional division.
Oskari Laaksonen (2017, third round) recorded a pair of minor penalties in 22:42 of work Saturday as Ilves U20 skated to a 3-2 overtime victory over Tappara.
On Sunday, Laaksonen was held without a point for the third-straight game as Ilves U20 doubled HPK 4-2.
At the 12-game mark in his Junior A season, the 18-year-old defender has one goal, four points and a minus-1 rating while averaging 24:26 of work per game.
