A four-goal first period saw the top-seeded Caps totally dominate the Leafs, but once again — just like in Game 3 — the Leafs scratched their way back to make things interesting.
Auston Matthews' third-period goal cut the lead to 4-3 with eight minutes to go, and the Air Canada Centre buzzed with frantic anticipation of perhaps a fourth consecutive overtime game.
The true test of the team's talent and character wasn't supposed to come this early for the Washington Capitals. How they respond to the pressure of needing to win now will be key.
Auston Matthews isn't the only youngster making waves this postseason, which has featured a raft of rallies, shocking potential sweeps and unexpected stars like Blues goalie Jake Allen.
A year ago, the last-place Maple Leafs won the Auston Matthews sweepstakes. Now hockey's former lovable losers are two wins away from knocking off the No. 1 team — and they ooze confidence.
But T.J. Oshie scored his second goal of the game at 12:59 to give Washington a crucial insurance goal.
Toronto native Tom Wilson scored twice for the Caps, saved a goal and made head coach Barry Trotz look smart for promoting the winger to the third line. Tyler Bozak scored in the dying seconds to make it close, but this time the Leafs weren't coming back.
Alex Ovechkin scored from his office on a bomb in the opening period and the Caps now head home in a much better mental place after opening the series with three consecutive overtimes games — two of them losses — to the No. 8-seeded Leafs.
The Caps were able to aggressively forecheck and force turnovers from the Leafs, which was the kind of thing most people expected to happen. Toronto looked disorganized defensively, especially in the first period, leaving Capitals players uncovered shift after shift. The Caps also tightened up their gap coverage, preventing many Leafs passing plays in transition that had been successful in the opening three games.
