Martone scored on his own rebound in front for a 5-on-3 power-play goal with 2:31 remaining. The play started when Trevor Zegras passed to Christian Dvorak at the left side of the net, who fed Martone in front. The forward stuck with it when his first shot was blocked, putting the second chance away by tucking the puck around Bruins goalie Joonas Korpisalo's left pad.
Dvorak had a goal and an assist, and Dan Vladar made 18 saves for Philadelphia (39-26-12).
Pavel Zacha scored and Korpisalo made 29 saves for Boston (43-26-9), which was playing for the second straight day. The Bruins lost 3-1 at the Tampa Bay Lightning on Saturday, but managed to maintain the first wild-card spot into the Stanley Cup Playoffs out of the Eastern Conference.
Dvorak gave the Flyers a 1-0 lead at 4:19 of the first period. Martone played a puck off the boards between his legs to send Dvorak and Travis Konecny off on a 2-on-1 rush. Dvorak kept the puck and snapped a shot past Korpisalo's glove from the right face-off circle.
Just 35 seconds into the third period, Zacha tied it 1-1 with a power-play goal. Vladar stopped David Pastrnak's one-timer from the left side, but the puck landed just outside the post to his right. Casey Mittelstadt centered it to Zacha, who lifted it over a fallen Vladar from the top of the crease.
