For 19-year-old Tomas Hertl Tuesday night's exhibition game against the Vancouver Canucks is one more step he still needs to take before guaranteeing himself a spot on the Sharks roster this season.

"Do I think that Tomas can play in the NHL? I do" Sharks coach Todd McLellan said after his team's morning skate. "But he's also played against a mixture of AHL and NHL players. I think the lineup Vancouver will bring in tonight will give us a good indication of whether he can play against the Keslers and the Sedins and the Hamhuises and that type of d-corps."

Hertl who has a goal and an assist in two games is again expected to skate on a line with Joe Thornton and Brent Burns.

"He shoots the puck very well. He skates real good for a big man. He looks solid so far" Thornton said of Hertl. "He's only played in this small surface for a little bit of time so I just expect him to get better and better."

A native of the Czech Republic Hertl's English is limited.

"We talk to him and I don't know if he understands what we're saying but he just nods and smiles" Thornton said. "Me and Burnzie will continue to talk with him and that's how you grow as a line."

This is the final home exhibition game for the Sharks who are 2-0-1 in the exhibition season.
