Edmonton superstar forward Leon Draisaitl became the first player in the NHL this season to reach 50 goals, then he added his 51st later Saturday night in dramatic fashion, as the Oilers defeated the rival Calgary Flames 3-2 in overtime at Rogers Place.

With the Oilers jostling for positioning in the Pacific Division down the playoff stretch and the all-important home-ice advantage hanging in the balance, four key pieces began falling like dominoes over the past two weeks.

Leon Draisaitl's second goal of the night -- his 51st of the season -- in a three-point game was the overtime winner to give the host Edmonton Oilers a 3-2 comeback victory over the Calgary Flames on Saturday.
