WASHINGTON — Nicklas Backstrom had a goal and two assists, and Alex Ovechkin scored once, leading the Washington Capitals and fill-in goalie Philipp Grubauer past the New York Islanders 4-3 Friday night to even their first-round playoff series at a game apiece.

After Washington’s two stars — Ovechkin led the NHL in goals, Backstrom was No. 1 in assists — were reunited on the top line, both scored to erase a 3-1 deficit. Jason Chimera netted the go-ahead goal with 12 1/2 minutes left.

It was the first time the Capitals had led in the series.

Grubauer was called up from the minors Friday to replace starting goalie Braden Holtby, who was ill. Grubauer, a 23-year-old from Germany, made 18 saves.

Canucks 4, Flames 1

VANCOUVER, British Columbia — Eddie Lack made 22 saves and Vancouver defeated Calgary to even the first-round playoff series at a game apiece.

Daniel Sedin, Chris Higgins, Ronalds Kenins and Radim Vrbata — into an empty net — scored for the Canucks, who snapped a seven-game losing streak at home in the playoffs dating to the 2011 Stanley Cup final.

Kris Russell scored late in the third period for the Flames to end Lack’s shutout bid.

The physical game was capped by a full brawl late in the third with fights erupting all over the ice deep in the Vancouver zone after a whistle.
