In the second, the Caps got a two-man advantage of their own, and they took advantage of the opportunity to take their first lead of the game. Nicklas Backstrom won a left dot draw in Toronto ice, pulling the puck back to Ovechkin at the left point. He fed Carlson, who wound up and fired from above the right circle, beating Frederik Andersen at 7:59 to give the Caps a 2-1 lead.
Washington turned in a strong middle frame, killing off a trio of penalties without incident and holding the Leafs without a shot on goal for 11 minutes and 32 seconds at one point. But just before the second intermission, Toronto pulled even.
Matthews netted his 10th goal of the season with 32.9 seconds left in the second, making a deft deflection of a Tyson Barrie shot from the right point.
More penalty trouble came the Caps' way early in the third, and Toronto finally made good on its seventh extra-man opportunity of the night. It was Matthews again, scoring his second of the night from the slot at 1:46, lifting the Leafs to a 3-2 lead.
Ovechkin seems to find the net with regularity in Toronto, and he tied the game a couple of minutes later. After Oshie made a dazzling rush to carry through neutral ice and around a couple of Leafs, Ovechkin was on the spot for a back-door tap-in at 4:10 of the third, knotting the score once again, this time at 3-3.
