Bruins prospect Trent Frederic, a first-round pick in 2016, pumped in four goals Friday in Team USA’s 9-3 shellacking of the Czech Republic in the bronze-medal game of the World Junior Championship in Buffalo.

Frederic, who has attended two development camps with the Bruins, is a sophomore center at the University of Wisconsin and could turn pro with Boston this spring.

Frederic was chosen 29th overall in 2016 with a pick that originally belonged to San Jose.

“The original [scouting report on Frederic] was, ‘We’ve got ourselves a checking, 200-foot center,’ ’’ said Bruins coach Bruce Cassidy, recalling what he saw of Frederic in the most recent July development camp. “A big body [6 feet 2 inches, 205 pounds]. So what does that mean about his hands?’’

Four goals against the Czechs might have helped answer that question and perhaps had Team USA wishing it had included Frederic on its Olympic squad.

“In development camp, I thought he had good hands around the net,’’ added Cassidy, when asked about Frederic on Saturday morning. “Maybe he’s not a guy who’ll come flying down the wing and score, but he’ll get to the dirty areas. If he can bring that on a consistent basis in college, then as he gets into a pro career . . . even if he ends up a third-line center, a valuable position in the NHL, if you can contribute offensively like [Ryan] Kesler in Anaheim . . . you are that much better.’’
