James Hagens makes his Team USA senior debut Friday in Switzerland, and Marco Sturm wants this trip to fast-track the 19-year-old's growth.

The Worlds open this morning in Zurich and Fribourg, and Boston is sending eight players across five national programs.

Three of them suit up for the Americans. Hagens leads that group as the youngest and least experienced, with two NHL games on his résumé.

Sturm has been transparent about the plan. He wants the kid playing against grown men, in a tournament setting, with the spotlight on. That's the whole point of letting him go.

The Bruins coach has done this before. He pulled Leon Draisaitl through this exact event years ago, and he's leaning on that experience now to push Hagens forward.

Mason Lohrei is the other story on the American blue line. He won gold at last year's Worlds and posted seven goals, 19 assists and a plus-17 over 73 games this season before missing the final three playoff games.

Fraser Minten lines up next to Sidney Crosby for Canada

Fraser Minten earned a Canada call after a full 82-game NHL grind. He finished with 17 goals, 35 points and a plus-21 rating, then captained the World Juniors back in 2024.

Now he gets to share ice with Sidney Crosby. That's not a small detail for a 21-year-old still building his identity at this level.

Henri Jokiharju heads to Finland after a stop-and-start season in Boston. He played only 41 NHL games, bounced in and out of the lineup, and needs reps that matter.

His last five with the Bruins produced two goals and four points. The tournament gives him minutes he wasn't always getting at home.

Joonas Korpisalo is Boston's lone goaltender on the trip. He went 10 wins with a .894 save percentage in 31 starts, numbers that don't exactly demand he be handed the crease back next fall.

The Finnish coaches will give him real work. That's something Korpisalo can use, because the conversation about Boston's goaltending picture isn't going to wait.

Alex Steeves got a late Team USA invite after a 43-game NHL stretch and nine goals. Lukas Reichel joined the Germans on Thursday in another last-minute add. Matej Blumel rounds it out for Czechia.

The Bruins finished 45-27-10. The roster needs work, the GM knows it, and a strong May from these eight could shift how the front office reads its own depth chart by July.

Hagens is the name that matters most. Boston drafted him to be a top-six center, and a productive Worlds buys him momentum nothing in development camp can replicate.
