This time, the Boston Bruins scored first and scored often, leaving the Washington Capitals to wrestle with their history of first-round collapses for at least another game.

Seeking to overcome a 3-1 series deficit for the first time in franchise history, the Bruins got three goals in the second period and forced a Game 6 in Boston on Sunday with Friday's 4-0 victory.Jason Allison and Sergei Samsonov fed each other with similar passes for the goals that gave Boston a 2-0 lead, reversing the 2-0 advantage that Washington had enjoyed in each of the four previous games. Rob DiMaio and Ray Bourque also scored, and Byron Dafoe stopped 26 shots for his first career playoff shutout.

The Capitals have blown two-game series leads four times in the first round since 1987, and it seemed the curse of the past set in fast as they blew several chances to take an early lead, then rocked back on their heels once Boston found the net the first time.

The Capitals still lead the series 3-2, with each team trying to win a playoff series for the first time since 1984. Boston is 0-17 in series in which they've trailed 3-1.

CANADIENS 5, PENGUINS 2: Mark Recchi scored twice in the third period and Montreal and goaltender Andy Moog held off a Pittsburgh rally to put the Penguins on the ropes.

Patrice Brisebois and Shayne Corson scored 1:29 apart midway through the second period as Montreal, the NHL's most storied franchise but one that hasn't won a playoff series in five years, took a 3-2 lead in the Eastern Conference quarterfinals. Game 6 will be Sunday night at the Molson Centre.

The Penguins can only hope that history is on their side again. The last time they lost a Game 5 at home to fall behind 3-2, they rallied to win not only the series but the Stanley Cup.

SABRES 3, FLYERS 2, OT: Michal Grosek's power-play goal 5:40 into overtime led Buffalo over the Philadelphia Flyers as the Sabres advanced to the Eastern Conference semifinals.

Buffalo, which had won only two of its previous 14 playoff series, eliminated the Flyers, a Stanley Cup finalist last year, in five games. It was the same number Philadelphia needed to beat Buffalo in last year's playoffs.

All three Sabres goals came on the power play, which produced nine goals in 32 chances during the series. Eight of the Sabres' last 13 goals in the series came on the power play.

Dominik Hasek made 35 saves for the Sabres, while Burke had 26 stops.
