Tyler Bozak scored 3:38 into overtime and the Blues fended off elimination in Game 5 of the Western Conference semifinals, overcoming a pair of deficits in a 5-4 victory over the Colorado Avalanche on Wednesday night.

Bozak, a fourth-line center, unleashed a shot from near the blueline that got past Darcy Kuemper, capping a remarkable comeback for St. Louis.

Robert Thomas had two goals, including the tying tally with 56 seconds left in regulation, for a resilient Blues team. It's the latest game-tying goal for the Blues when facing elimination, according to NHL Stats. Vladimir Tarasenko and Justin Faulk also scored, Nick Leddy had four assists and Pavel Buchnevich had two.

They never doubted - even down 3-0 late in the second period and 4-3 late in the third.

The comeback offset a hat trick from Nathan MacKinnon, who looked like he might have just turned in a signature moment with goal No. 3. He went end-to-end, working his way around Blues defenseman Leddy with nifty stick work and lifting a shot over goaltender Ville Husso for a 4-3 lead. It was his second career postseason hat trick.

Game 6 is Friday in St. Louis.

The Blues have rallied from a 3-1 deficit to take a playoff series twice in their history - 1999 against Phoenix and 1991 versus Detroit.
