Matt Calvert banged home a rebound 1 minute, 10 seconds into the second overtime and the Columbus Blue Jackets earned the first playoff victory in franchise history with a 4-3 win over the Penguins in Pittsburgh on Saturday night.
Pittsburgh's Marc-Andre Fleury stuffed the initial shot by Cam Atkinson, but Calvert stood all alone at the left post and wristed a shot into the open net to even the Eastern Conference quarterfinals at one game each.
Game 3 will be Monday in Columbus.
Jack Johnson tied the game with 6:01 left in regulation for the Blue Jackets. Ryan Johansen also scored the first playoff goal of his career for Columbus. Sergei Bobrovsky overcame a shaky start to finish with 39 saves.
Brian Gibbons scored twice and Matt Niskanen added his second goal of the playoffs, but Pittsburgh was outplayed for much of the final three-plus periods. Fleury made 41 stops but was helpless on the game-winner.
The Penguins have dropped four straight home overtime playoff games and blew a chance to take a 2-0 series lead when they failed to bury the Blue Jackets early on.
Defenseman Barret Jackman scored on a drive through traffic, giving the St. Louis Blues their second straight 4-3 overtime home victory over the Chicago Blackhawks for a two-games-to-none series lead against the defending Stanley Cup champions.
St. Louis rallied after Chicago defenseman Brent Seabrook received a five-minute major and game misconduct penalty for a vicious elbow to the head of Blues captain David Backes, who had to be helped off the ice. He went straight to the locker room and did not return for the extra period.
Vladimir Tarasenko forced overtime with his second goal of the series, beating Corey Crawford with a wrist shot that banged off the right post and in with 6.4 seconds to go. Kevin Shattenkirk had a goal and two assists for the Blues, who also got a goal from Chris Porter.
Duncan Keith, Seabrook, and Michael Rozsival scored in a span of five shots to put the Blackhawks up 3-2 early in the third. But Seabrook's penalty proved costly, and he could be suspended for Game 3 in Chicago on Monday night.
The Blues took the opener in triple-overtime and fought off a Chicago rally in a game that began less than 39 hours later.
The Blackhawks got no help from a power play that went 0 for 4 and is 0 for 9 since Seabrook scored on their first chance in Game 1.
Tarasenko made the most of the Blues' six-on-four advantage after pulling goalie Ryan Miller.
Keith's goal late in the second ended a scoring drought of 119 minutes, 27 seconds for Chicago since a three-goal first period in Game 1.
Before Chicago's rally, Miller stopped 53 consecutive shots.
