Ryan McDonagh scored at 4:58 of overtime and the visiting New York Rangers pulled out a stunning 3-2 win over the Calgary Flames on Thursday night.

The teams were just two seconds from a shootout when McDonagh beat Flames netminder Henrik Larsson on a snapshot off a rebound from the back boards.

Marian Gaborik and Brandon Prust also scored for the Rangers, who notched their second straight victory and won in Calgary for the first time since 2002.

New York netminder Henrik Lundqvist turned aside 33 shots to follow up his 40-save shutout in Vancouver on Tuesday night.

Jarome Iginla had a goal and assist for Calgary, which battled back from a pair of one-goal deficits in the opening period.

Gaborik put the Rangers on top with the team's first power-play goal of the season, a one-timer at 4:53 of the first. Brad Richards notched his 500th career assist on the play.

Iginla knotted it 58 seconds later, taking a pass from Alex Tanguay and shoveling it past Lindqvist on a bang-bang play.

New York regained the lead on Prust's shorthanded goal at 13:42, capitalizing on a lackadaisical play by Calgary's Jay Bouwmeester along the corner boards.

The lead was short-lived as the Flames pulled even on Mark Giordano's power-play tally at 15:51.
