OTTAWA - Colin Greening scored 7:39 into double overtime, and the Ottawa Senators rallied for a 2-1 victory over the Pittsburgh Penguins that cut their series deficit to 2-1 on Sunday night.
Daniel Alfredsson got Ottawa even 1-1 by scoring a short-handed goal with 29 seconds left in regulation, just after the Senators pulled goalie Craig Anderson for an extra skater.
Anderson made 49 saves, including 18 after regulation. Tomas Vokoun stopped 46 shots for Pittsburgh and took his first loss (4-1) since taking over for No. 1 Penguins goalie Marc-Andre Fleury.
Game 4 of the Eastern Conference semifinal series will be in Ottawa on Wednesday.
Tyler Kennedy scored with just over a minute to play in the second period to give the Penguins a 1-0 lead. That goal stood up until Alfredsson tied it.
BRUINS 5, RANGERS 2
BOSTON (AP) ? Johnny Boychuk broke a tie midway through the second period, and Boston scored two goals in the third to beat the New York Rangers and take a 2-0 lead in the Eastern Conference semifinal series.
Boychuk's third playoff goal made it 3-2 at 12:08 of the second. Brad Marchand, whose overtime goal won the opener, and Milan Lucic stretched the Bruins' lead in the final period.
Boston rookie Torey Krug scored the first goal before Ryan Callahan tied it for the Rangers in the first period. Gregory Campbell made it 2-1, and New York pulled even again on Rick Nash's goal in the second.
Games 3 and 4 of the best-of-seven series will be played in New York.
Rangers goalie Henrik Lundqvist, last year's Vezina Trophy winner, had his second straight tough game after posting consecutive shutouts in Games 6 and 7 of the first round against the Washington Capitals when the Rangers faced elimination.
Tuukka Rask was solid for Boston, stopping 35 shots.
