CALGARY, Alberta (AP) The Anaheim Ducks tightened their grip on their playoff series against the Calgary Flames.
Matt Beleskey broke a tie on a power play early in the third period and the Anaheim Ducks beat the Calgary Flames 4-2 on Friday night in Game 4 of the Western Conference semifinal.
Anaheim leads the series 3-1. Game 5 is Sunday night in Anaheim, where the Flames have just one win there - a playoff victory in 2006 - in the last 11 years.
''We know our situation,'' Calgary coach Bob Hartley said. ''Obviously we need to win. We'll be a desperate group, as always. It's a tough loss tonight, we're going to swallow it and tomorrow we'll be back at work.''
Jakob Silfverberg had a goal and an assist, Andrew Cogliano also scored, and Patrick Maroon added an empty-net goal. Frederik Andersen made 25 saves to hand Calgary its first home loss of the postseason.
Sean Monahan and Micheal Ferland scored for Calgary, and Karri Ramo stopped 25 shots.
Anaheim was 2 for 4 on the power play. Calgary failed to score on a two-man advantage for 56 seconds in the third, finishing 0 for 2.
''I felt that we had good momentum, good pressure ...'' Hartley said. ''But here's a team with lots of depth and they capitalized on some chances. That was the difference.''
The Ducks opened the third period with a 4-minute man advantage after Calgary's Joe Colborne was slapped with a double minor for high-sticking Francois Beauchemin at the second-period buzzer.
Beleskey batted in a rebound at 1:11.
With Ramo pulled for an extra attacker, Maroon sealed the win with the empty-netter with 37 seconds left.
Anaheim drew even late in the second off a turnover in Calgary's end. Seconds after the Flames killed off a minor for too many men, center Kyle Palmieri stripped Johnny Gaudreau of the puck and passed to Cogliano, who beat Ramo between the pads with 3:18 left.
Anaheim opened the scoring on Silfverberg's power-play goal at 3:58 of the first.
The Flames scored twice in a 1:07 span to take the lead. Monahan tied it at 4:37, and Ferland stuck at 5:44.
''It makes sense that if we go home 3-1, we're in a better position than they are,'' Ducks head coach Bruce Boudreau said prior to the game. ''Two-two, they've got momentum coming into our building, so we'd much prefer the 3-1.''
Notes: Calgary beefed up with rugged wingers Lance Bouma and Ferland returning to the lineup from injury. Anaheim forward Tomas Fleischmann played for the first time in the series, replacing Emerson Etem. ... Francois Beauchemin had his 34th and 35th career playoff assists for the Ducks.
