MONTREAL — Carey Price got his second shutout and Andrei Kostitsyn scored twice to lead the Montreal Canadiens to a 5-0 win over the Boston Bruins on Monday night in the deciding game of their first-round playoff series.

Price stopped 25 shots overall, including 11 shots in the opening period. He got his first playoff shutout in a 1-0 win in Game 4.

Mike Komisarek opened the scoring 3:31 in amid one of the first of countless roars from the raucous Bell Centre crowd over the course of the evening.

The Canadiens took control of the game in the second, outshooting the Bruins 17-6 while building a three-goal lead on a superb goal by Streit midway through the period and Kostitsyn's second goal of the series at 15:13.

Kostitsyn punctuated the win with his second of the game, a power-play goal with 2:02 remaining in the third. Sergei Kostitsyn scored with 7.3 seconds remaining.

Top-seeded Montreal will face Philadelphia in the second round, if the Flyers win their Eastern Conference quarterfinal against Washington. Otherwise, the Canadiens will face the New York Rangers.

Alex Kovalev assisted on Montreal's first two goals as coach Guy Carbonneau moved him to a line with Saku Koivu and Chris Higgins.

The move allowed rookie Sergei Kostitsyn to play on another line alongside his brother, Andrei, and center Tomas Plekanec as Carbonneau spread out the Canadiens' offense.

Komisarek got credit for his first career playoff goal as his point shot struck Bruins center Petteri Nokelainen's stick, causing a deflection that left Thomas no chance to recover and stop.

CAPITALS 4, FLYERS 2: At Philadelphia, Alex Ovechkin truly was "Alexander the Great" with the Washington Capitals' season on the line.

Held without a goal for four straight games, Ovechkin scored twice in the third period to lift the Capitals to a 4-2 win over the Philadelphia Flyers on Monday night and send the series back to Washington for a decisive Game 7.

The Capitals have rallied back from a 3-1 hole and have a chance to win only the second Game 7 in franchise history Tuesday night. The Caps have a shot to advance on home ice thanks to Ovechkin's timely goals. They are trying to become the 21st team in league history to come back from a 3-1 deficit and win a best-of-seven series.
