Road teams 4-0 after Tampa Bay ties series

Alex Killorn scored the tiebreaker with about eight minutes left Thursday night, Andrei Vasilevskiy made 36 saves, and the visiting Tampa Bay Lightning weathered the equivalent of more than a period without a shot on goal to edge the Washington Capitals, 4-2.

The victory evened the best-of-seven Eastern Conference playoff final at two games apiece and meant that the home teams were winless in the series.

Killorn was left pretty much alone on a defensive breakdown by Washington and scored six 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 Alex Ovechkin assist — and defenseman Dmitry Orlov.

The Lightning will play host to Game 5 Saturday night with Game 6 Monday back in Washington.

The Capitals, who eliminated the two-time reigning Stanley Cup champion Penguins in the second round, fell to 3-5 overall at home in these playoffs.

They were booed late in the first period, which ended with the Lightning ahead, 21. The Lightning won Game 4 despite going nearly 21 full minutes of game time — the last 10:41 of the first period and the initial 10:11 of the second — without putting an official shot on net.

They won, despite the fact that the Capitals finally got back center Nicklas Backstrom back in their lineup.

Backstrom, who was third on the team in points this season behind Ovechkin and Kuznetsov. Backstrom had missed four consecutive games because of an injured right hand.
