Carey Price made 43 saves, Brendan Gallagher scored in the first period, and the Montreal Canadiens defeated the Ottawa Senators 2-0 Sunday night to advance to the second round of the NHL playoffs.

Max Pacioretty sealed the win with an empty-net goal with 1 second remaining.

Montreal won the best-of-seven series in six games, but lost two in a row after taking a 3-0 series lead — and Ottawa nearly sent it to a deciding seventh game.

Price, nominated for the Vezina Trophy as the league's top goalie, rebounded after allowing five goals in Game 5 with a masterful effort as the Senators outshot the Canadiens 43-20.

Montreal, which reached the Eastern Conference finals last spring, is in the second round for a second consecutive year for the first time since 1992 and '93.
