David Desharnais scored late in the first overtime to lift the Edmonton Oilers to a 4-3 win over the Sharks on Thursday night, pushing San Jose to the brink of elimination in the NHL playoffs.

Desharnais, in the slot, one-timed a Leon Draisaitl cross-ice pass past Sharks goaltender Martin Jones to cap an overtime session dominated by Edmonton.

The Oilers lead the Western Conference quarterfinal series 3-2 with Game 6 Saturday night in San Jose.

The series winner takes on the Anaheim Ducks in Round 2.

Patrick Maroon, Mark Letestu, and Oscar Klefbom also scored for Edmonton. Mikkel Boedker, Patrick Marleau, and David Schlemko had goals for San Jose.

The Oilers — looking for a bounce-back game after a 7-0 beat-down by the Sharks in Game 4 — dominated the first 10 minutes, energized by the deafening roar of the orange and blue-clad fans at Rogers Place.
