There are some decisions to be made at the bottom rungs of the defense corps but the most interesting story line developing at Buffalo Sabres training camp is the play of Zemgus Girgensons.

With seemingly few spots available the 19-year-old Latvian winger is trying to force his way on to the roster.

Girgensons has been a standout in camp and in the first two exhibition games. If he keeps it up it may be hard for the Sabres to send him back to Rochester.

The Sabres open the First Niagara Center portion of the preseason with two games in three days tonight at 7 against Carolina (Radio 550 AM) and Saturday against Toronto. Girgensons is getting a long look and will certainly play in at least one of those games. He might play in both.

Girgensons is the only Sabre with three points in the first two games collecting two goals in Sunday’s shootout win in Montreal and an assist in Tuesday’s victory in Columbus. The 6-foot-2 194-pounder played more than 34 minutes and has a plus-3 rating.

His second goal in Montreal was a sensational effort of power down the right-wing boards finished by a sizzling snap shot past rookie goaltender Zach Fucale.

“Most people talk about if I’m able to put up points. That’s one of the things I’ve been working on” Girgensons said this week. “I’ve been working on my shooting. It’s about me burying chances. I’ve had some problems with it. I have to put that behind me and be better offensively.

“I was pretty happy with myself. At the start of last season the second goal would have probably hit in the netting up there given a souvenir to a fan.”

The Sabres drafted Girgensons in 2012 with the No. 14 overall pick – the highest ever for a Latvian – out of Dubuque of the United States Hockey League. He captained the club and even earned the nickname “The Latvian Locomotive” for his hard-charging physical style.

He started last season as the youngest player in the AHL and the Sabres have eased him into the pro game by putting him at left wing rather than his natural center slot. Coach Ron Rolston reiterated this week if Girgensons makes the big club out of camp it will be on the wing.

Girgensons started slowly in the AHL seeing limited ice and no power-play time until he started to get up to speed with the pro style. He played in 61 games collecting six goals and 11 assists.

But by the time the playoffs rolled around Girgensons had become the Amerks’ top forward. He scored three of the team’s five goals in its three-game sweep at the hands of the Toronto Marlies.

“He had a lot more purpose to his game offensively” recalled Rolston.
