Brandon Dubinsky scored with 22.5 seconds left in regulation to force overtime, and Nick Foligno's wrist shot just inside the blue line 2:49 into the extra session gave the Columbus Blue Jackets a 4-3 home victory over the Pittsburgh Penguins on Wednesday night.
The Blue Jackets overcame a 3-0 deficit for their first home playoff victory in the franchise's 13 seasons, sending the series back to Pittsburgh for Game 5 on Saturday night tied at two games apiece.
The winner of the series will face the victor of the Flyers-Rangers series.
Stars 4, Ducks 2 - Cody Eakin and Alex Goligoski scored on Dallas' first two shots in the third period and Dallas beat top-seeded Anaheim in Game 4 of a best-of-seven series that is all even now.
Even without captain Ryan Getzlaf, a surprise late scratch with an upper-body injury, and healthy scratch Teemu Selane, the Ducks jumped out to a 2-0 lead in the first period.
