It certainly wasn’t easy, but Johnny Boychuk’s first career overtime goal proved to be the difference as the Islanders moved into a tie for first place in the Metropolitan Division with a 4-3 overtime win over the Washington Capitals. The Isles built a 3-0 lead early in the third period, but for the fourth time this month they allowed a 3-goal margin to get away as the Caps forced overtime. The Isles, playing before yet another sellout crowd of 16,170 at the Nassau Veterans Memorial Coliseum, improved to 5-1-1 in their last seven games.
