Top American & Finish Prospects From the 2026 World Junior Summer Showcase – The Hockey Writers – World Junior Hockey Championship

Finland is the only team at the World Junior Summer Showcase that drew all three versions of the United States. The Finns beat USA White 4-1, lost to USA Blue 5-1, and edged the merged American squad 3-2 in Windsor, which makes their week a clean way to sort out who helped the most on both sides.

The Showcase is less a national-pride event and more of a “showcase” to scouts, a stretch of games where newly drafted players make early cases for December’s World Junior roster and undrafted ones put themselves on the 2027 map with scouts in the building. Here are the three Americans and three Finns who did the most with the chance the Summer Showcase gave them.

Team USA

Ethan Wyttenbach

Ethan Wyttenbach was the most productive player on the ice across the three games. The Calgary Flames prospect had three assists against Sweden, two goals in the 5-1 win over Finland, and another in the 3-2 loss, six points in three games while running his line from the middle of the ice. That tracks with what he did last season: He put up 1.46 points per game at Quinnipiac University as one of the top scorers in college hockey, a playmaking winger who creates through the neutral zone and finds seams.

Calgary took Wyttenbach in the fifth round in 2025, and he was left off the U.S. team at the 2026 World Junior Championship, a call Daily Faceoff’s Steven Ellis figured the Americans wouldn’t make twice. A camp like this makes it hard to. His college production points to a middle-six scoring role at the NHL level down the road, and the nearer question is whether this summer earns him the December roster spot he missed a year ago.

Sammy Nelson

Sammy Nelson made the loudest single play of any American against Finland, scoring shorthanded and taking U.S. Player of the Game honors in the 3-2 loss. That fits his trajectory better than his showcase box score does. The 6-foot-2 center finished second on the U.S. National Team Development Program team with 54 points last season and carries an A rating on NHL Central Scouting’s early 2027 watch list, for now, the kind of grade that points to the first round.

Nelson is eligible for the 2027 NHL Draft, and this is his draft-minus-one summer. He accelerated through the development program and heads to Notre Dame this fall, a year early, to play alongside his brothers. Between the size, the shot, and the center habits, he is the youngest of the six and the one with the most ceiling still ahead of him. Expect his name high in 2027 conversations by midseason.

Wyatt Cullen

Wyatt Cullen carries the best pedigree of the group as the No. 10 pick in the 2026 NHL Draft, and he looked it on Day 1. Centering the top line for USA Blue in a 6-1 rout of Sweden, he scored on a backdoor play and drove a unit that combined for seven points. The two games against Finland were quieter, with Finland’s checking keeping him off the sheet in both the 5-1 and the 3-2.

Nashville drafted Cullen as a right wing who spent most of his development-program time on the wall, and the center audition is the wrinkle worth watching. If it takes, the Predators have a versatile top-six forward who can play the middle; if it doesn’t, he slides back to a scoring-wing track. Either way, the pedigree holds up, and he’ll want a louder close to the week to match it.

Team Finland

Patrik Kerkola

Patrik Kerkola turned in the best individual performance of the entire series. He made 34 saves in the 3-2 win over the United States while Finland got outshot 36 to 18, including 18 in the second period when the Americans took over the run of play. He hasn’t hidden what he wants out of the week, telling NHL.com his goal is “to be that guy, the No. 1 goalie.”

Kerkola is Finland’s only returning player from the 2026 World Junior Championship, where he sat as the third goalie and never played. The 6-foot-2 netminder is eligible for the 2027 NHL Draft and spent last season getting real reps with KalPa in Liiga, plus Champions League games and a stint in Mestis. The bigger near-term story is the crease itself: Jester Rossi stopped 25 in the Game 1 win and Kerkola stopped 34 in Game 3, with Juuso Ainasto’s rough middle game in between, and December’s starting job is a three-way race that Kerkola just moved to the front of.

Aapo Katavisto

Aapo Katavisto was Finland’s engine in the opener. He had a goal and an assist in the 4-1 win over USA White, driving the cycle and living around the net, the most noticeable Finnish skater of the three games, even if the next two were quieter. It matched a strong season with Kiekko-Espoo’s junior team, where he generated chances at a high rate and earned a handful of Liiga looks.

Katavisto is eligible for the 2027 NHL Draft and is headed to Northern Michigan in the NCAA, the increasingly common path for Finnish forwards chasing development against older competition. His speed and compete are the selling points, and the college move gives scouts a full season of viewings against men. He’s a name to file away and track through the year rather than one to rank firmly yet.

Vilho Vanhatalo

Vilho Vanhatalo was the only drafted Finn of the six to score, and he did it in the biggest game. He beat Harrison Boettiger on a first-period breakaway to open the 3-2 win and added an assist back in Game 1. At 6-foot-4, he has the kind of frame Florida tends to chase, and the Panthers took him in the sixth round in 2026, 168th overall, after he slid well past where his ranking suggested.

Vanhatalo comes up through Tappara, the same Tampere club that produced Panthers captain Aleksander Barkov and that Barkov now part-owns, so he follows the exact hometown-to-Florida path. He models his game after Matthew Knies, another power forward, and he’s off to Ottawa in the Ontario Hockey League this season to keep developing. This is a long-term project rather than a fast track, but his frame and the Barkov pipeline make Vanhatalo an easy one to follow.

The Showcase is one week and a small sample, but it’s the first read on a long road to Edmonton and Red Deer in December. For the drafted names, it’s about roster spots and long-term fit; for Nelson, Kerkola, and Katavisto, it’s about a 2027 stock that ticked up in front of the right people.
