Fortunately for the Blues, their rookie goalie withstood the onslaught, only allowing a goal by forward Tomas Hertl on the power play that brought the Sharks within 2-1 at 6:48 of the third period.
The final two minutes of madness, as Binnington described it, featured the Blues icing the puck three times and hanging on in desperation.
"I [was] just trying to stay strong and obviously close it out, after last game, especially," Binnington said. "Again, the team did a great job in front of me, battling hard, competing, staying disciplined. Face-offs were huge, and boys were blocking shots everywhere. It's just madness, and you hope for the best and try to close the door."
By doing just that, Binnington set a Blues record for victories in a single playoff season with 10.
"That's a great honor, obviously," he said. "I'm having a lot of fun back here playing with this team, and they're doing a great job. They limited chances tonight. I think we played a complete game, so I just try do to my job."
His teammates felt he did more than that.
"Obviously he gives us a ton of confidence," Bozak said. "We know he's going to make the right play, make the big saves and also handle the puck really well and help us break out."
This series has been unpredictable. No team has won consecutive games. The Blues were probably the better team in Game 3 and lost. The Sharks were probably the better team in Game 4 and suffered a similar fate.
Game 5 is at San Jose on Sunday (3 p.m. ET; NBC, CBC, SN, TVAS).
The only sure thing from a St. Louis standpoint is the stability the Blues will look for from their coach and their goalie.
As always.
"We're in a good spot here," defenseman Alex Pietrangelo said. "We played a couple of good games. Obviously we didn't end the last one the way we wanted to, but we feel like we've got some momentum."
