TORONTO -- It's hard to blame Dougie Hamilton if the 19-year-old defenseman doesn't quite know whether he's coming or going.

One of the top prospects at his position in the sport, Hamilton was given a small taste of life in the NHL recently when he was among 29 players invited to take part in the National Hockey League Players' Association 2012 Rookie Showcase.

Hamilton, decked out in Boston Bruins black and gold, was waiting to be photographed for his first NHL hockey card as he spoke confidently of his desire to play in Boston this season. In nearly the same breath though, he said he also is prepared to return to the Niagara IceDogs of the Ontario Hockey League for the 2012-13 season.

Josh Leivo and Frank Corrado scored unassisted goals in the third period to send the Sudbury Wolves of the Ontario Hockey League to a 2-0 victory against the Waterloo Black Hawks of the United States Hockey League in the gold-medal game of the 2012 Junior Club World Cup on Sunday at Omsk Arena in Russia.

The Junior Club World Cup was in its second year. It featured teams from eight countries this year, and for the first time, a USHL and OHL franchise. The tournament is designed to match top teams from the best junior hockey leagues from around the world.

Leivo, a third-round pick of the Toronto Maple Leafs in 2011, scored 7:55 into the third off a breakaway to snap a scoreless tie. The Wolves then struck 35 seconds later to extend the lead to 2-0 when Corrado, a defenseman, unleashed a wrist shot from the slot that beat Waterloo goalie Eamon McAdam (22 saves). Leivo, 19, finished the tournament with six goals and 11 points in six games.

Eamon McAdam and the Waterloo Black Hawks made a third-period lead stand up despite a tenacious comeback effort from the Omsk Hawks for a 7-3 victory Thursday at the 2012 Junior Club World Cup in Russia.

Entering the final period, Waterloo led 4-1 when McAdam turned aside a penalty shot at 1:33 by Ivan Fishchenko. Omsk cut the deficit via the power play at 13:04 on a goal from Evgeny Mozer, who flipped in a rebound. Mozer then struck again just over a minute later, burying a cross-ice feed on a rush up ice.

But McAdam made the save of the game, flashing his glove to snag a hard, low blast with three minutes to play.

The Sudbury Wolves of the Ontario Hockey and Waterloo Black Hawks of the United States Hockey League rebounded with impressive victories on Wednesday in round-robin action at the 2012 Junior Club World Cup in Omsk, Russia.

The Black Hawks (2-1) scored four unanswered goals bridging the second and third periods to overcome a 3-1 deficit on the way to a 5-3 victory against the Norway National Team at Omsk Arena. Meanwhile, at Blinov Arena, Joshua Leivo struck for three goals and one assist to lead Sudbury (2-1) to a 7-2 decision over the Danish National Team. Both Waterloo and Sudbury were coming off losses on Tuesday.

The Waterloo Black Hawks of the United States Hockey League and Sudbury Wolves of the Ontario Hockey League each suffered setbacks in round-robin play at the 2012 Junior Club World Cup on Monday at Omsk Arena in Omsk, Russia.

The Black Hawks lost 3-1 to Dynamo Shinnik of Belarus, while Sudbury lost to HC Riga Jr. of Latvia 2-1 in a shootout.

Waterloo (1-1-0) is competing in Group A along with teams from Belarus, Czech Republic, Norway and host Russia. Sudbury (1-1-0) is in Group B with Denmark, Finland, Latvia, and Sweden. During round-robin play, teams play games against teams in their respective group. The two clubs with the best records in each group following round-robin play will advance to the semifinal round.

The Mississauga St. Michael's Majors were finishing off a 3-1 win against the Niagara Ice Dogs in their home opener on Oct. 3, 2008, when 17-year-old forward William Wallen suddenly started experiencing blinding headaches. Wallen, who had arrived in Mississauga just weeks earlier after playing in his native Sweden, became disoriented and eventually vomited. Something was wrong.

"We're taught in second-year medical school that the worst headache of your life is a ruptured aneurysm," said Dr. Tim Rindlisbacher, the Majors' team physician who was at the game that night. "I wanted him to get to the hospital really fast."

What some thought might be a bad headache turned out to be a bulging blood vessel in Wallen's brain that had burst and was bleeding. There was a 50 percent chance he might die. But in an inspiring comeback that would make waves across the hockey world, Wallen was back on the ice just a few months later.

Sam Reinhart won't be eligible for the NHL Draft until 2014, but he's already making quite a name for himself.

The center, who plays for the Kootenay Ice of the Western Hockey League, scored the go-ahead goal 1:13 into the second period as Canada held off the Czech Republic for a 5-2 win Friday in one semifinal of the Ivan Hlinka Memorial Tournament, played at Thereza Arena in Breclav, Czech Republic.

Canada, which has won the past four summer under-18 tournaments, will face Finland in the gold-medal game Saturday. Finland scored a 5-4 overtime win against Sweden in the other semifinal.

Reinhart also had a pair of assists in the win. Bo Horvat had a pair of goals, and Nathan MacKinnon, a candidate to be the first player picked at the 2013 NHL Draft, had three assists. Nicolas Petan and Max Domi also had goals for Canada.

J.T. Compher, a left wing expected to be a first-round pick in the 2013 NHL Draft, was one of 23 players named Thursday to the U.S. National Team Development Program Under-18 team for the 2012-13 season.

Compher, a 6-foot, 165-pound forward, led the USNTDP U-17 team last season with 27 assists and was second with 42 points in 40 games. He also had six goals and three assists in 14 games with the U-18 team last season.

Compher is one of 19 players from the U-17 team to earn a spot with the U-18 team this season. Also on that list is Tyler Kelleher. The 5-6, 147-pound right wing led the U-17 team last season with 25 goals and 47 points.

Canada already had clinched first place in Group B at the Ivan Hlinka Memorial Tournament, but wanted to end preliminary-round play Wednesday on a positive note. It took until the final 3:45 of the game, but the Canadians left the ice at Zimny Stadion in Piestany, Slovakia with smiles on their faces following a dramatic 3-2, come-from-behind win against Slovakia.

Center Sam Reinhart, a top candidate for the 2014 NHL Draft who currently plays for the Kootenay Ice in the Western Hockey League, capped Canada's comeback by scoring the winning goal with 53 seconds left in regulation.

Defenseman Joshua Morrissey, who plays for the Prince Albert Raiders of the WHL and is a candidate to be a first-round pick in the 2013 draft, had a hand in all three Canada goals, scoring once and assisting on the others.

Slovakia led 2-0 heading into the final minutes of regulation on goals by Kristian Horvat and Martin Ambroz and shutout goaltending by Maros Mikolas. But Ryan Kujawinski, a center with Kingston of the Ontario Hockey League, got Canada on the board when he scored off a Morrissey setup with 3:45 left.

Max Domi, son of former NHL player Tie Domi and a highly regarded 2013 NHL Draft prospect, had two goals and two assists and Anthony Duclair had the go-ahead goal and an assist as a quick-strike scoring attack paced Canada to a 7-5 win against Sweden on Tuesday at the Memorial of Ivan Hlinka Tournament.

In the game, played at Zimny Stadion in Piestany, Slovakia, Canada got goals from six different players en route to their second in as many days. They beat Switzerland 4-1 on Monday.

Nathan McKinnon, Morgan Klimchuk, Curtis Lazar and Sam Reinhart also scored for Canada, which scored three power-play goals and another shorthanded.
