TORONTO -- Tom Wilson and T.J. Oshie scored two goals each and the Washington Capitals defeated the Toronto Maple Leafs 5-4 on Wednesday night to even the Eastern Conference first-round playoff series 2-2.

Alex Ovechkin also scored for the Capitals while Nicklas Backstrom added two assists.

Zach Hyman, James van Riemsdyk, Auston Matthews and Tyler Bozak scored for the Maple Leafs. Mitch Marner and William Nylander each had two assists.

Braden Holtby made 30 saves in the Capitals goal. Toronto goaltender Fredrik Andersen stopped 22 shots.

Washington led 4-1 at the end of the first period and 4-2 after the second.

The Capitals took two minor penalties in the final seven seconds of the second period -- Lars Eller for delay of game and Brooks Orpik for slashing -- giving the Maple Leafs a five-on-three power play to open the third period. Washington killed off both penalties.

The Capitals put the puck in the net at 8:11 but it was disallowed because of goaltender interference.

Matthews cut the lead to one with his second playoff goal at 12:00 of the third on a rebound after Matt Hunwick's shot from the point.

Oshie restored the two-goal margin 59 seconds later when he was able to break in alone uncontested to score from the slot.

With Andersen removed for an extra attacker, Bozak scored at 19:33 of the third.

As they did in Game 3, the Capitals scored the first two goals of the game early in the first period.

Oshie notched his first of the playoffs at 2:58, converting a rebound from the low slot.

One minute later, Bozak was penalized for high sticking and Ovechkin rifled his third goal of the playoffs from the left wing at 4:34.

Hyman scored for Toronto at 5:16 of the first period, his first of the playoffs as a shot by defenseman Jake Gardiner bounced in off his foot.

Toronto nearly scored again. A puck squirted past Holtby and was about to slide over the line, when Wilson sprawled to clear the puck off the line.

That set up a rush down the right wing by Eller, who circled behind the goal, shot the puck toward the net and Wilson tipped it in at 13:41.

Wilson scored again, his third of the playoffs, at 16:04, from the low slot on a pass from Andre Burakovsky and Washington led 4-1.

The Capitals outshot the Maple Leafs 15-6 in the first period.

Toronto scored a power-play goal at 5:39 of the second period, the second of the series by van Riemsdyk, whose shot from the right circle deflected off a defender. Backstrom was serving a holding-the-stick minor.
