Capitals 4, Islanders 3

Playing in his first career playoff game in place of an "under-the-weather" Braden Holtby, German-born goaltender Philipp Grubauer kept the Washington Capitals' hopes of a deep playoff run alive, stopping 18 of 21 shots in a comeback victory over the New York Islanders.

Trailing by a pair of goals late in the second period, the Capitals received unanswered goals by Alex Ovechkin, Nicklas Backstrom and Jason Chimera to pull out the victory and even the Eastern Conference first-round series at 1-1.

Cal Clutterbuck, Ryan Strome and Kyle Okposo scored for the Islanders, while goaltender Jaroslav Halak stopped 31 of 35 shots.

Game Three is on Sunday in New York.
