Winnipeg was up 2-0 after the first period on goals by Adam Lowry and Kevin Hayes. Connor Hellebuyck made 26 saves as the Jets lost their sixth straight at home, including the regular season.

The Blues' win marked the first time in 15 years, and fourth time overall, the road team has won each of the first five games in a seven-game series. According to a league stat, when a best-of-seven NHL playoff series is tied 2-2, the winner of Game 5 takes the series 78.8 per cent all time (205-55).

St. Louis went on its first power play with 21 seconds remaining in the second period when Jacob Trouba was called for roughing. The period ended with Winnipeg holding the 22-21 edge in shots on goal.

O'Reilly scored with 11 seconds remaining in the power play, off a rebound in a crowd in front of the net at 1:29 of the third to pull St. Louis to 2-1.

Schenn tied it with 6:09 remaining following a review. Oskar Sundqvist passed the puck over to Schenn and then slid into the net and knocked it off, but it was ruled Schenn had shot the puck in before a defensive player caused the net to come off.

Winnipeg mounted a 2-0 lead after the first period, even though the Blues had the 15-12 advantage for shots on goal.

After fans stopped cheering, some on the rink side of St. Louis's net started chanting "You look nervous" to Binnington. Before Game 1, a video clip of the rookie saying, "Do I look nervous?" to reporters made the rounds on social media.

Hayes cut to the front of the net with 6:25 left in the first and sent the puck under Binnington's pad to make it 2-0 with his second goal of the playoffs.

Hayes almost scored twice more in the second period.

He took away his own goal when his close shot slid under Binnington and started going toward the goal line. He tried to swipe it across, but his stick pulled the puck out instead.

Hayes also had a breakaway late in the period, but Binnington sprawled on the ice and the shot from the side went into his pads.

Winnipeg got a four-minute power play when Robert Thomas was dinged for high sticking Mark Scheifele in the face shield, but the Jets only had one shot on goal after a number of misses and blocked attempts.

Another Winnipeg power play early in the third delivered one shot on goal.

NOTES: The last series in which the road team won the first five games was in 2004 when Calgary beat San Jose in six games, clinching it in Game 6 at home. ... Schwartz's goal was the second-latest winning goal in regulation in franchise postseason history. Only Gino Cavallini's goal with 9 seconds left in Game 3 of the 1990 division finals against Chicago came later. ... St. Louis was missing injured third-pairing D Robert Bortuzzo, who was replaced by Carl Gunnarsson. ... Lowry's goal was the fifth scored in the opening minute this postseason, tied for the most in the opening round of any playoffs. The others were in 1981, 2012, 2016.
