John Carlson appeared to give Washington the lead on the power play at 15:56, coming in off the point and shooting from the high slot. The Oilers challenged for offside and it was determined Backstrom had entered the zone before Oshie carried the puck across the blue line, and the goal was waved off.
"All the guys came up and celebrated, and I said right away, 'I think it's offside,'" Backstrom said. "I saw it bounce off Oshie's foot there, but that happens."
Cody Ceci gave the Oilers a 2-1 lead at 18:12, on a rebound off a shot from Malone.
Oshie tied it 2-2 on the power play at 6:13 of the third period. He took a pass from Backstrom on the right wing and scored on a shot from the face-off circle. The assist gave Backstrom 1,000 NHL points.
Malone made it 3-2 at 10:31, converting a centering pass from Zack Kassian. It was Malone's first goal in 67 games, since Dec. 3, 2015 with the Carolina Hurricanes in a 5-1 loss to the New Jersey Devils.
"I don't think it has really sunk in yet, to be honest," Malone said. "It feels pretty awesome. I was just really happy that we got the two points at the end of the game there. It is tough to have an individual game like that and feel good about yourself when you don't get the two points."
