SAN JOSE –- Tomas Hertl and Roman Polak will suit up for the Czech team, while Sharks rookie Joonas Donskoi was named to Team Finland on Wednesday morning for the upcoming World Cup of Hockey this summer.
Defenseman Marc-Edouard Vlasic was named to the Team Canada roster, but Brent Burns did not make the team.
Joe Pavelski was named to Team USA later on Wednesday afternoon.
Each of the competing teams was set to release a minimum of 16 names on Wednesday, with the rest of the roster to be filled out no later than June 1.
Hertl, 22, has 15 goals and 33 points for the Sharks this season, his third in the NHL. He was a possibility for the Czech team at the Olympics in 2014 before suffering a knee injury in December of his rookie year.
Polak, 29, was acquired by the Sharks on Feb. 22 and has 13 points (1g, 12a) in 59 games with San Jose and Toronto this season. He is a pending unrestricted free agent.
Donskoi, 23, has been the Sharks’ most pleasantly surprising player this season after he was signed as a free agent last May. In 57 games, he has 10 goals and 27 points.
The World Cup of Hockey is an eight-team tournament that will run from Sep. 17 – Oct. 1 at the Air Canada Centre in Toronto.

The Sharks signed free agent forward Jon Martin, 20, to an entry-level contract on Wednesday. The six-foot-two, 220-pounder leads the WHL’s Swift Current Broncos with 66 points (36g, 30a) in 60 games this season, and is tied for ninth in the league in goals.
"Jon is a well-rounded player who brings a high skill set but also a tough, physical game," general manager Doug Wilson said in a statement.
