While Jaden Schwartz has been one of the Blues’ key performers during their playoff run, Dmitrij Jaskin has been forced to watch from high above the ice, a healthy scratch for each of the team’s first nine games.

Jaskin finally got his chance to play on Friday night, replacing the injured Alexander Steen, and he and Schwartz combined to ensure that the Blues will have at least one more game to play.

Jaskin scored his first goal since Dec. 3, one of eight shots he had on goal, the most he has ever had in any game in his career in either the regular season or the playoffs.

Schwartz scored his fourth goal of the playoffs, and his third game-winner, when he knocked in the rebound of a shot by Colton Parayko just 25 seconds into the third period, snapping a 1-1 tie.

The 2-1 win kept the Blues’ season alive and extended the second-round series to game six on Sunday in Nashville.

Jaskin’s goal 5:43 into the second period marked the first time in the series the Blues had scored the first goal of the game.

The lead didn’t last, however, as the Blues were called for two minor penalties at exactly the same time, 12:41 of the second period. Alex Pietrangelo was called for tripping and Patrik Berglund for holding, putting the Predators on a 5-on-3 power play.

The Blues had their own 5-on-3 power play late in the first period but could not capitalize on the chance, but the Predators did, when James Neal scored at 13:50 of the period.

The Blues had another power play chance at the end of the second period, which carried over to the start of the third period. The penalty expired eight seconds before Schwartz’s game-winning goal.

“He's played unbelievable,” coach Mike Yeo said of Schwartz. “He's not taking a backseat to anybody anymore and I think that's showing up in his play.”

Yeo and the Blues knew what to expect from Schwartz, but they really had no idea what Jaskin would be able to contribute in his first game in more than a month. With Steen not able to play, however, they really did not have much choice but to give Jaskin a chance.

"I don't know that we thought he would be as good as he was tonight because he was impressive,” Yeo said.

The Blues were 0-of-5 on the power play in the game. They have scored only twice on the power play on 28 opportunities in their 10 playoff games this season.

Jake Allen stopped 21 of 22 Nashville shots, while the Blues fired 32 shots on goal against Pekka Rinne.
