WASHINGTON (AP) - Alex Killorn scored the tiebreaker with about 8 minutes left, Andrei Vasilevskiy made 36 saves, and the Tampa Bay Lightning weathered the equivalent of more than a period without a shot on goal to edge the Washington Capitals 4-2 on Thursday night, evening the Eastern Conference final at two games apiece.

Killorn was left pretty much alone during a defensive breakdown by Washington and scored 6 seconds after a Tampa Bay power play expired, putting in a pass from Ondrej Palat.

Steven Stamkos and Brayden Point scored Tampa Bay's first two goals, and Anthony Cirelli added an empty-netter with a second left.

Washington's goals came from Evgeny Kuznetsov - off an assist by Alex Ovechkin - and defenseman Dmitry Orlov.

The Lightning host Game 5 on Saturday night, with Game 6 back in Washington on Monday.

The road team has won every game in the series so far.
