ST. LOUIS -- A long offensive zone cycle enabled the Florida Panthers to sweep a five-game road trip for the first time in their history.
Vincent Trocheck scored with 4.6 seconds remaining to give the Panthers a 2-1 win against the St. Louis Blues at Scottrade Center on Monday.
Trocheck scored from the high slot with traffic in front on a shot Blues goalie Jake Allen never saw to give Florida (28-20-10) its eighth win in nine games.

Jonathan Marchessault also scored for the Panthers, and James Reimer made 26 saves.
According to Elias Sports Bureau, it's the latest the Panthers have ever scored a goal in regulation to win.
"It was just a strong cycling down low by Jussi [Jokinen] and [Reilly Smith]," Trocheck said. "They tried to get the puck out, but [Mark] Pysyk made a great play keeping the puck in going down the wall. He threw it up top to me. I took one shot, they blocked it. Got it back, I had a lane. Jussi was in front and I don't think Allen even saw it. I just kind of did the easy work."

The Panthers return home for a four-game homestand in third place in the Atlantic Division. They are tied with the Boston Bruins at 66 points apiece, but Florida has played one fewer game.
"First off, I couldn't be more proud," Panthers coach Tom Rowe said. "The coaching staff, everybody that's part of the team, the front office back home. We couldn't be more proud of these players. It's a great group of players and everybody deserves it.
"It's been a long season, it's been a hard season and now everything is coming together but again, we've got a long way to go. It's going to be a dogfight until the end of the season."
Kyle Brodziak scored, and Allen made 31 saves for St. Louis (31-24-5), which has lost back-to-back games and enters a five-day break.

"It's terrible. Terrible finish," Allen said. "We needed a win tonight just to have positive momentum into the break. We had a chance, came [up] short."
Allen lamented that the Blues failed to control the puck once in the game's final 41.3 seconds from the moment the Panthers won a faceoff in the Blues zone until Trocheck scored.
"You've got to battle. You've got to get pucks put, pucks in," Allen said. "We had 30 seconds left to salvage a point in a game that we played not good. Those are huge points right now. Couldn't end up with two points and it slipped away."
Marchessault put the Panthers ahead 1-0 at 1:40 of the first period after Kevin Shattenkirk turned the puck over behind the Blues net.
Brodziak tied it 2:54 into the third period when his shot from the slot was deflected in front.

They said it
"I think we put ourselves in a position where we should have a bad taste in our mouth for a couple of days." -- Blues coach Mike Yeo
"We needed it. We know we're in the playoff race. We talked about it before the road trip that these five games were going to be huge for us coming into the playoff race. The fact that we went into California and swept three great teams, then Nashville and St. Louis, also two great teams, so it showed a lot of courage on our team." -- Panthers center Vincent Trocheck
"Yeah, it's tough but you shut your mind off, you prepare for a good long stretch to close the season. We're in a big fight for a playoff spot right now. We all realize what's at stake now and we're going to come back after the break with our best foot forward." -- Blues left wing Scottie Upshall
