The number of Sabres prospects with a chance to compete for the world junior championship continues to increase.

Jake McCabe (United States), Mikhail Grigorenko (Russia) and Zemgus Girgensons (Latvia) have been selected to their country’s tryout camps for the under-20 tournament, which begins Dec. 26 in Russia. Girgensons is playing for the Rochester Americans, and it’s possible he will stay with the club rather than fly overseas.

The Sabres selected Grigorenko, who plays for Quebec of the Quebec Major Junior Hockey League, and Girgensons in the first round last June. McCabe, who attends the University of Wisconsin, was picked in the second round. Also, Daniel Catenacci, who has 17 goals and 43 points in 29 games with Owen Sound of the Ontario Hockey League, has been invited to Canada’s world junior camp. There are 37 Canadian players who will compete for a roster spot.

The Sabres selected Catenacci in the third round of the 2011 draft.

Joel Armia, the Sabres’ first-round pick in 2011, is invited to Finland’s world junior camp. He represented Finland in the last two tournaments.
