PHILADELPHIA -- Wayne Simmonds and Sean Couturier each inched closer their career highs in goals and goaltender Steve Mason stopped 23 shots to record his third shutout of the season to lead the Flyers to a 4-0 win over the Pittsburgh Penguins Wednesday night at the Wells Fargo Center.

Claude Giroux and Dale Weise also scored for the Flyers (32-29-8, 72 points), who snapped a three-game losing streak and moved within four points of the Toronto Maple Leafs and five points of the Tampa Bay Lightning and New York Islanders in their pursuit of the second wild-card spot in the Eastern Conference standings.

The Flyers, Islanders and Lightning each have 13 games remaining. The Maple Leafs have 14 games left.

Mason improved to 20-19-7 with his first shutout since Feb. 28

The Penguins' loss was their first in regulation since March 1, snapping a 5-0-1 stretch. At 43-17-9 and 95 points, they remain two points behind the Washington Capitals, who sit atop the Metropolitan Division.

Penguins goaltender Matt Murray (26-9-3) took the loss, allowing four goals on 28 shots.

Two nights removed from a cross-continental flight from Calgary, where they completed a 3-0-1 road trip, the Penguins looked sluggish in the opening two periods and watched the Flyers grab a 2-0 lead on second-period goals by Couturier and Simmonds.

Couturier got things started one minute into the period when he scored his 11th goal, matching his total from last season. Couturier crashed the net and was the recipient of a fortuitous bounce as Brayden Schenn's cross-ice pass caromed off linemate Weise and Murray and onto the stick of Couturier, who is closing in on his career high of 15 goals set two seasons ago.

Less than 5 1/2 minutes later Simmonds showed his athleticism and gave the Flyers a 2-0 lead with his 29th goal and 15th on the power play. Simmonds leaped to get out of the way of Shayne Gostisbehere's shot, then flipped the rebound past Murray. He is now three goals away from matching his career high of 32 goals set last season.

Giroux and Weise finished off the Penguins with late third-period goals, their 14th and third of the season, respectively.
