Montreal blew an early two-goal lead after Jesperi Kotkaniemi and Nick Suzuki scored in the first. Carey Price finished with 39 saves for the Canadiens. Sidney Crosby and Bryan Rust scored in the second period for Pittsburgh. Murray finished with 32 saves, after he wasn't announced as the starter until earlier Saturday.
Pittsburgh's Conor Sheary missed the net with a wide shot on a penalty shot with 3:03 left in regulation after he got hooked by Petry during a breakaway. It was Montreal's turn at 6:46 of overtime, as Jonathan Drouin had the puck roll off his stick after he was awarded a penalty shot.
Blackhawks goalie Corey Crawford stopped 25 of 29 shots, helping Chicago withstand a late Oilers rush after the Blackhawks raced to a 4-1 lead through 20 minutes.
Flames 4, Jets 1
A dominating special-teams performance, led by second-period power-play goals from Johnny Gaudreau and Mikael Backlund, helped Calgary beat Winnipeg in the opener of a best-of-five Western Conference qualifying round series in Edmonton.
The Jets lost not only the series opener but also a pair of key players due to injury. Top-line center Mark Scheifele left the game before the six-minute mark after his leg appeared to be clipped by the skate of Matthew Tkachuk near the boards while the Flames forward was attempting a body check. Sniper Patrik Laine left midway through the third period due to an apparent injury to his right hand or wrist.
