Andrew Shaw stuffed home a rebound on a power play with 4:19 remaining, minutes after the Chicago Blackhawks won a coach's challenge to negate a goal, and the defending Stanley Cup champions pulled even with the St. Louis Blues in their first-round series with a 3-2 victory Friday night.

Corey Crawford had a strong game in net and Duncan Keith also scored for Chicago in his first game back from a six-game suspension for a dangerous high stick to Minnesota's Charlie Coyle. Keith assisted on rookie Artemi Panarin's clinching empty-net goal with 1:34 to go, and Patrick Kane also had two assists.

The series shifts to Chicago with Game 3 on Sunday.

Vladimir Tarasenko started the scoring for St. Louis and nearly had the go-ahead goal at 12:14 of the third. After a lengthy replay, it was determined that Jori Lehtera had been offside by inches.

Tarasenko was in the penalty box with 8 seconds left to serve in a slashing penalty when Shaw, who had 14 goals in the regular season, scored on the rebound of a shot by Brent Seabrook.

The Blues lost a challenge, and their timeout, unsuccessfully arguing that goalie Brian Elliott had been pushed into the net.

Kevin Shattenkirk scored for St. Louis with 2 seconds to go, making it a one-goal decision.

Keith gave the Blackhawks their first goal of the series, tying it at 1 with 5 seconds left in the second period.

Both teams had several good scoring chances in a wide-open second period, including a shot off the crossbar by Panarin and a breakaway by Kane that fizzled when defenseman Jay Bouwmeester got a piece of his stick late, before both teams cashed in.

Tarasenko, who led the Blues with a career-best 40 goals, got his first of the playoffs on a one-timer at 15:20 set up when Lehtera stole the puck from Michal Rozsival on the forecheck.

Jonathan Toews won the faceoff and Kane got the puck to Keith on the tying goal, a shot through traffic from the point with 4.4 seconds left in the second.

NOTES: Besides Keith, the Blackhawks gave forward Richard Panik his first start with defenseman Erik Gustafsson and forward Brandon Mashinter sitting. The Blues had no changes. ... Blackhawks F Andrew Ladd played Game 1, returned to Chicago, missing by minutes the birth of his third child late Wednesday night, and was back in St. Louis for Game 2. "My wife was very cool about allowing me to go," Ladd said.
