BUFFALO, N.Y. (AP) -Thomas Vanek is certainly making it look simple. For that matter, so are the Buffalo Sabres.
Vanek scored his NHL-leading sixth goal and added two assists, and Ales Kotalik scored twice in the Sabres' 5-2 victory over the Vancouver Canucks on Friday night.
Jaroslav Spacek had a goal and assist, and Clarke MacArthur also scored for the unbeaten Sabres, who won their fourth straight to start the season.
It's the third time in franchise history Buffalo has opened with four wins, and second time in the last three years.
"Well, it's not easy," said Vanek, who has scored in each of the Sabres' first four games this season. "We got an early jump on them, and from there on out we played pretty well."
That they did. After busting out with a three-goal first-period that included two power-play goals, the Sabres cruised the rest of the way - thanks to a stingy defense that has allowed just five goals, and the play of the four-year veteran Vanek.
"I think he has more confidence," Kotalik said. "He's cleaned up some little stuff, and now he's a real fine player."
Kotalik was the beneficiary of Vanek's hard work in the third period when Vanek outraced Vancouver defenseman Shane O'Brien to the puck along the left boards at the Canucks' blueline before cutting to the net. O'Brien hauled Vanek down from behind, but Vanek was still able to control the puck and serve a perfect pass that Kotalik one-timed past Vancouver goalie Curtis Sanford from the high slot to give Buffalo a 5-2 lead.
"I'm looking at the effort behind the plays," Sabres coach Lindy Ruff said. "I'm looking at the play made on that last goal. It's that effort that really sticks out."
Ryan Miller finished with 23 saves for the Sabres.
Ryan Kesler and Steve Bernier scored for the Canucks, who beat defending Stanley Cup champion Detroit in overtime on Thursday.
Sanford had 26 saves for Vancouver in his first start of the season in place of Roberto Luongo. The Canucks' captain got the night off after allowing 12 goals in his last three starts.
Buffalo put this one away early, scoring three straight goals in a 12-minute span in the opening period. Spacek started the blitz with a power-play goal just a minute in, and MacArthur made it 2-0 with Buffalo up a man at 8:30.
Kotalik increased the advantage to 3-0 with just under 7 minutes to go in the first when his wrist shot from the high slot squirted through Sanford's pads.
"I wasn't playing my game in the first period and it showed," Sanford said. "I was fighting the puck a little bit, and all of a sudden the bounces were going their way."
Kesler closed the gap with his third of the year just 2 minutes into the second period, but Vanek lifted a backhand over Sanford's shoulder from in tight midway through the second to restore Buffalo's three-goal lead.
He didn't get his sixth goal last season until the 21st game.
"I felt pretty good during the second half last season, but I'm showing up on the scoresheet now and I think people are making a big deal out of it," Vanek said. "I've been on hot streaks before and then got pretty cold, so now I'm just trying to be consistent."
Bernier made it 4-2 early in the third period before Kotalik capped the scoring with 5:49 left.
"Anytime you spot a team that's only given up three goals in three games a three-goal lead right off the bat, you're obviously not giving yourself a chance to win," Vancouver coach Alain Vigneault said.
