Barry Trotz returned to his old home arena to face the team he coached to the Stanley Cup. He left with his new team in first place.

The New York Islanders beat the defending champion Washington Capitals 2-0 on Friday night to win their fourth in a row and leapfrog his former team into first place in the Metropolitan Division. In true Trotz fashion, the Islanders suffocated the Capitals to win for the 14th time in 17 games.

"We just talked about climbing," Trotz said. "It just happened that the Caps were the next team in front of us."

Josh Bailey and Cal Clutterbuck scored third-period goals, and Thomas Greiss made 19 saves for his second shutout of the season. New York held Washington under 20 shots and improved to 7-0 in the second half of back-to-back sets this season.

Trotz was honored with a first-period video tribute. Even though he faced the Capitals in Brooklyn earlier this season, getting his Stanley Cup ring then, he expected another emotional night in Washington.

Fans gave Trotz a lengthy standing ovation throughout a video summing up his four years in Washington. The 56-year-old left the Capitals in a contract dispute in June and was hired by the Islanders days later.

"My heart got full of all the good memories," Trotz said. "I was looking up there. I was trying not to look too much because I was getting pretty close to that sensitive side of myself."

Calgary 6, Detroit 4: Sam Bennett scored twice, including the go-ahead goal late in the third period, and the host Flames went 3-for-3 on the power play to beat the Red Wings to improve to 6-0-1 in their past seven games.

Florida 3, Toronto 1: Mike Matheson scored the winning goal off an assist from Vincent Trocheck, back after missing 27 games because of a broken ankle, and the host Panthers ended a seven-game losing streak.

Pittsburgh 3, Arizona 2 (OT): Phil Kessel redirected a Sidney Crosby shot past Darcy Kuemper on an overtime power play for the visiting Penguins.
