WASHINGTON — The precocious Russian forward drafted in the first round by the Washington Capitals finally delivered a breathtaking, winning goal in a Game 7. No, not Alex Ovechkin — Evgeny Kuznetsov.

Skating around every opponent on the ice, Kuznetsov scored the go-ahead goal with 7:18 remaining, and Braden Holtby only needed to make 10 saves Monday night, lifting the Washington Capitals past the New York Islanders 2-1 in the first round of the Eastern Conference playoffs.

Kuznetsov, a rookie, scored the sort of athletic, breathtaking goal his better-known teammate, Ovechkin, often does, taking the puck from the right boards and heading across the ice before sending a rising shot over sprawling goalie Jaroslav Halak.

Lightning 5, Red Wings 2

DETROIT — Tyler Johnson scored two goals in his latest stellar performance, and the Lightning forced a Game 7 in their first-round playoff series.

Johnson and Jason Garrison scored in the first period, and Johnson added another goal in the second to give the Lightning a 3-0 lead. Tomas Tatar scored twice for Detroit, but Alex Killorn answered with an unassisted goal with 5:09 remaining, and Cedric Paquette added an empty-netter.

Ben Bishop made 22 saves for the Lightning.
