PITTSBURGH — Marc-Andre Fleury capped a career week with another shutout for the Pittsburgh Penguins.

Fleury made 18 saves for his second consecutive shutout, Chris Kunitz scored twice, and the Penguins earned their fourth win in a row with a 5-0 victory over the Buffalo Sabres on Saturday night.

“I don’t think I’ve had two straight shutouts in the NHL,” Fleury said. “It feels good though.”

Fleury was right. He recorded back-to-back regular-season shutouts for the first time in his career.

Coming off a 3-0 win over the defending Stanley Cup champion Los Angeles Kings, Fleury posted his third shutout in four games and the 31st of his NHL career.

He has stopped 98 of the last 101 shots he faced and has held opponents without a goal in 10 of his past 12 periods.

“You have a feeling your goaltender is in a zone, so we went back to him tonight,” Penguins’ coach Mike Johnston said. “He was good in Nashville and continued right through this week.

“You can’t say enough about having a goaltender that will play like that.”

Evgeni Malkin, Patric Hornqvist and Blake Comeau also scored for Pittsburgh, and captain Sidney Crosby had three assists. Kunitz, with four goals in his last two games, has seven this season.

Malkin also had two assists, extending his point streak to 10 games. Crosby has a point in 18 straight games against Buffalo, his longest active run against any team.

The Penguins finished 3 for 5 on the power play. It was the fourth straight game and seventh time in 10 games that Pittsburgh’s power play scored multiple goals. Pittsburgh is 10 for 21 on the power play during its four-game winning streak.

“We’ve done some good things, guys have capitalized, but you need some luck, too,” Crosby said. “We’ll try to keep riding that. It’s tough to do, but hopefully we’ll continue to carry that momentum and build confidence.”

The Penguins have outscored opponents 19-3 during the last four games. They defeated the Sabres for the 13th time in 17 games, earning their eighth win in the past 11 played in Pittsburgh.

Jhonas Enroth made 29 saves for the Sabres, who were shut out for the fifth time in 12 games this season.

“It’s very tough, especially today,” Enroth said. “I didn’t play my best game and just felt that we weren’t really close in this one.”

Buffalo entered with 12 non-shootout goals in 11 games. The Sabres, who lost for the seventh time in eight games, are 2-9-1 and have the second-fewest points in the Eastern Conference.
