Scheifele cut it to 6-5 on a power play at 14:55, and Pionk hit the post with 3:13 remaining.
"When we got it to 6-5, I think everyone on the bench thought we were going to tie the game," Schmidt said. "We hadn't played our best game, and we'd given up so many good chances, but we still had a chance to win the game.
"You just can't put yourself in a spot where the whole game is uphill."
Raymond scored an empty-net goal with 1:20 left for the 7-5 final.
"We were getting a little nervous on the bench, but this was a big game to win," Raymond said. "It felt really good walking away from here with a win."
NOTES:Seider is the second-youngest defenseman with a four-assist game for the Red Wings; Reed Larson was 38 days younger when he did it March 28, 1978. … Detroit has scored seven goals in a game three times this season (Nov. 17 against the San Jose Sharks; Dec. 21 against the Tampa Bay Lightning). … Red Wings forward Tyler Bertuzzi played for the first time since Nov. 30. Bertuzzi, who has only played 10 games after injuries to both hands, did not have a shot on goal in 17:48 of ice time. … Winnipeg forward Kyle Connor had an assist on Ehlers' goal, giving him 50 points (20 goals, 30 assists) for the sixth straight season. He's only the fourth player in Jets/Atlanta Thrashers history to reach that mark, joining Ilya Kovalchuk (eight), Blake Wheeler (seven) and Scheifele (seven).
