JETS 3, CAPITALS 2: Defenseman Dustin Byfuglien scored to snap a tie midway into the third period as host Winnipeg pulled to within two points of eighth-place Washington.
Captain Andrew Ladd netted his eighth goal in 11 games and Nik Antropov also tallied for the Jets, who secured their fourth straight victory at MTS Centre.
Brooks Laich recorded his fourth goal in six contests and Mathieu Perreault added a power-play goal for the Capitals, who saw their four-game winning streak come to an end.
With the game tied at 2-2, Evander Kane skated around a defender and wristed a shot that Byfuglien tapped past Tomas Vokoun. Byfuglien's 11th goal came at 9:21 of the third period.
Ondrej Pavelec, who finished with 20 saves, preserved the victory by stopping 10 of the 11 shots in the final session.
Antropov gave Winnipeg a 2-1 advantage with 3:50 remaining in the second period. Stationed behind the net, Tim Stapleton patiently waited for Antropov to position himself in front - with the latter converting the feed for his 12th goal.
