Even in a postseason full of overtime games, the Anaheim Ducks' 4-3 win against the Edmonton Oilers was one for the history books. The 22nd game to go past regulation in the 2017 Stanley Cup Playoffs was decided when forward Corey Perry scored at 6:57 of the second overtime -- and after the Ducks became the first team in Stanley Cup Playoff history to force OT after trailing by three goals with less than four minutes remaining in the third period.
