The Philadelphia Flyers have hit the NHL play-off spots after a 3-2 win over reigning champions the Chicago Blackhawks.
Radko Gudas scored the winner in the third period, after goals from Ryan White and Brayden Schenn had cancelled out efforts from Blackhawks duo Marian Hossa and Jonathan Toews respectively on Wednesday.
The win moves the Flyers into the last wildcard spot in the Eastern Conference.
The New York Rangers jumped up to second in the Metropolitan Division with their 2-1 win over the Anaheim Ducks.
Anaheim's Jamie McGinn had the home side 1-0 up, but Kevin Klein's double proved their undoing as the visitors took an important win from their travels.
The St Louis Blues will be keen to avoid a repeat of their shock 6-4 loss to the Edmonton Oilers as the play-offs approach.
The Blues remain second in the Western Division, but could not overcome the Oilers who shot to a 2-0 lead through Ryan Nugent-Hopkins and Taylor Hall.
Before the end of the game, Nugent-Hopkins would double his tally, team-mate Mark Letestu scored two of his own with Leon Draisaitl also getting on the scoresheet.
The Calgary Flames posted a big 4-1 win over the Winnipeg Jets, having shot to a 3-0 lead in the first period alone as Joe Colborne, Michael Frolik and Sean Monahan put the former in a strong position early on.
Drew Stafford pulled one back for the visiting Jets, but it proved a mere consolation as Mark Giordano re-established the Flames' three-goal lead late in the third period.
The Colorado Avalanche beat the Vancouver Canucks 3-1, while the Montreal Canadiens trumped the Buffalo Sabres 3-2 in overtime.
