ST. LOUIS -- Here’s a quick look at the St. Louis Blues’ 4-3 three-overtime win over the Chicago Blackhawks in Game 1 of their Western Conference first-round series at the Scottrade Center on Thursday.

How it happened: The Blackhawks and Blues set the bar high for the remainder of the series. The Blues’ Alexander Steen scored 26 seconds into the third overtime for the win. The Blackhawks looked to have the game secured in regulation. They were leading 3-2 heading into the final two minutes of the third period. Jaden Schwartz saved the Blues by scoring in front of the net with 1:56 remaining in the third period. The Blackhawks had been leading 3-2 since the end of the first period. Patrick Kane broke a 2-2 tie at 18:24 of the first period, when he received a stretch pass from Jonathan Toews and scored on a breakaway. The Blackhawks’ Johnny Oduya and Brent Seabrook and the Blues’ Adam Cracknell and Vladimir Tarasenko also scored first-period goals. The Blackhawks nearly won the game in the first overtime, but Blues forward Maxim Lapierre blocked a Blackhawks’ shot while standing behind goaltender Ryan Miller in the net. Blackhawks goaltender Corey Crawford made 48 saves on 52 shots. Miller made 39 saves on 42 shots. The Blackhawks failed to score on two overtime power plays, and the Blues squandered one overtime power-play opportunity of their own.

What it means: The Blues went up 1-0 in the series and held onto their home-ice advantage. The Blues have scored a number of clutch third-period goals against the Blackhawks this season. The Blues pulled out a 3-2 win over the Blackhawks by scoring in the final minute of the third period on Oct. 9. The Blues came back from a 5-3 deficit when they scored two goals in the final four minutes of the third period on Dec. 28, then won in the shootout. The Blues’ win on Thursday marked their first victory since April 3.

Both teams benefited in getting some of their top players back. Tarasenko had missed the previous 15 games for the Blues. Kane was out the previous 12 games, and Toews missed six games.
