Malone scored on a breakaway off a lead pass from defenseman Seth Griffith.
Dylan Holloway scored, and Jack Campbell made 34 saves for the Oilers.

Lindholm put Calgary ahead 1-0 at 12:55 of the second period.
Mikael Backlund appeared to have given the Flames a two-goal lead at 17:21 of the third period on a rebound. But the Oilers used a coach’s challenge for goaltender interference, and after video review it was determined forward Blake Coleman interfered with Campbell before the puck went into the net.
Holloway tied it 1-1 on the power play at 18:20 when he one-timed a shot from the left face-off circle.
Calgary nearly won it when Yegor Sharangovich knocked in a rebound in the final seconds of the third, but time expired before the puck crossed the goal line.
