Philadelphia's missing power play apparently has been found.
The Flyers were 3-for-31 with the man-advantage in the first six games, but scored twice in the second period to pad their lead.
First Danny Briere again beat Paul Gaustad on a draw to the left of goalie Ryan Miller, this time winning the puck back to Mike Richards at the right point. Richards fired a shot through traffic that somehow found Briere. With Miller out playing the angle, Briere had an easy tap-in.
That goal five seconds after the Sabres' Tyler Myers was sent off for interference.
Later in the period, Claude Giroux fired a shot from the left circle that Miller never saw through a James van Riemsdyk screen at 10:19 that made it 3-0. The goal came 1:10 into a hooking penalty on the Sabres' Chris Butler.
The Sabres were far better in the second, nearly scoring a power-play goal following an interference penalty in Giroux just 1:04 in. They had three shots on the man-advantage, which was more than they had in the entire first period.
