ST. LOUIS (AP) Brayden Schenn knows he has to do dig in around the net and make things happen.
Schenn's tiebreaking goal came off a rebound as he backhanded it past prone Panthers goalie Roberto Luongo with 3:55 remaining.
''I got to more of that,'' Schenn said. ''I've got to go to the net more. That's where the pucks are always ending up whether it's a tip or a rebound. If you go to the net, good things are going to happen. I got to do a better job of doing that.''
Florida coach Bob Boughner believed there should've been a penalty on Schenn before the goal.
''I thought it was a cross-check,'' Boughner said. ''The guy that cross-checks is the guy that gets the puck and it's in the back of our net so that's how it all played out.''
David Perron had two goals and Ivan Barbashev also scored for St. Louis, which had lost three of four and eight of its last 11 games. Jake Allen made stopped 22 shots to improve to 2-4-0 in his career against Florida.
Barbashev got the Blues on the scoreboard at 1:28 as he scored from the slot to tie the score 1-1.
Perron's second goal, also on an assist by Schwartz, came when the puck deflected in off Florida's Frank Vatrano at 11:12 to make it 3-1.
''He's a good player,'' Perron said about Schwartz. ''He makes good plays.''
The Panthers tied it with two goals 1:28 apart. Just 34 seconds after Perron put the Blues up by two, Weegar got his first of the season from inside the right circle. Hoffman tied it from in front with 6:46 remaining.
The Blues took a timeout and regrouped.
''It's always important never to panic,'' Perron said. ''Always. We've done that too much this year.''
The Panthers went ahead 1-0 when Dadonov scored with 4 1/2 minutes left in the first period. It was Dadonov's fifth goal in his last seven games.
The Blues failed to score on two power-play chances in the first period. St. Louis went on a 4-minute power play just 29 seconds into the game and recorded just one shot on goal. Later in the period, St. Louis had another power play and had just one shot on goal.
St. Louis had a goal waved off at the 5:37 mark of the first. From outside the blue line, Robert Bartuzzo fired in a pass to go around the net. The puck hit referee Tim Peel, who was in the corner. The puck bounced toward the goal and slipped in past Luongo's skate. However, it was ruled no goal because it hit the official. Referee Furman South made the ruling according to Rule 78.5 under disallowed goals.
Peel left the ice. He returned at the beginning of the second period.
''I didn't know the rule obviously,'' Bartuzzo said. ''I threw my hands in the air. I felt bad. Anytime you hit a ref, it's tough on them. I apologized to him in the second period. He's a good guy. Maybe I'll buy him a dinner sometime.''
