Joffrey Lupul netted a rebound during a power play 6:06 into overtime in Game 7 to lift the Philadelphia Flyers past Alex Ovechkin and the Washington Capitals 3-2 on Tuesday to reach the conference semifinals. The Flyers led the best-of-seven series Eastern Conference first-round series 3-1 before allowing the Capitals to pull even. Lupul found space in front of the net to get a backhander past Cristobal Huet for his first postseason goal after Washington's goalie had deflected Kimmo Timonen's shot. There were 9 seconds left in the Flyers' man advantage after defenseman Tom Poti was sent off for tripping - the first penalty since the second period in a rough-and-tumble game that suited Philadelphia's style. The Flyers avoided what would have been a monumental collapse and won a playoff series for the first time since before the lockout: In 2004, they reached the Eastern Conference finals. Now Philadelphia, which had the worst record in franchise history last season and the fewest points in the NHL, will play the top-seeded Montreal Canadiens in the conference semifinals. Washington, meanwhile, dropped to 1-5 in Game 7s and is still waiting for its first playoff series victory since 1998, when it made it to the Stanley Cup finals. The Capitals will have to take solace in getting to the postseason for the first time since 2003, managing a remarkable turnaround under career minor league coach Bruce Boudreau, who took over for the fired Glen Hanlon on Thanksgiving with the team 6-14-1 and last in the 30-team NHL. San Jose 5, Calgary 3: At San Jose, California, veteran San Jose center Jeremy Roenick had two goals and two assists, including the tying and go-ahead scores midway through the Sharks' four-goal second period, in a victory over the Calgary Flames in Game 7 of their first-round playoff series. Evgeni Nabokov made 19 saves for second-seeded San Jose in front of a deafening crowd at the first Game 7 in Shark Tank history. After the Sharks fell behind 2-1 early in the second period, San Jose's formidable talent finally overwhelmed the Flames with four goals in less than nine minutes, chasing goalie Miikka Kiprusoff. The Sharks earned their fourth straight trip to the second round, where they'll face the Pacific Division-rival Dallas Stars. Joe Thornton, Joe Pavelski and rookie Devin Setoguchi also scored for the Sharks, who took 41 shots while thoroughly controlling most of the final two periods. Owen Nolan, captain Jarome Iginla and Wayne Primeau scored for the seventh-seeded Flames, who fell apart defensively after forcing Game 7 with a shutout win in Calgary two nights earlier. The impressive win capped an exhausting two weeks for the Sharks, who fell behind 2-1 in the series before rallying for two improbable late goals in their Game 4 victory. San Jose then gave its worst effort of the series in Game 6, leaving many wondering whether the Sharks had the grit necessary to survive a physical opponent. __
