David Booth had three goals and an assist, and the Florida Panthers beat the St. Louis Blues 5-3 on Saturday night to move into fifth place in the Eastern Conference.

Nathan Horton and Radek Dvorak also scored for the Panthers, a point ahead of sixth- place Montreal. Florida, coming off a 4-1 loss to Pittsburgh Thursday night, hasn't lost back-to-back games in regulation since the end of December.

David Backes scored twice for St. Louis, which lost in regulation for only the second time in 11 games (7-2-2). Brad Boyes also scored.

The Blues, 12th in the Western Conference, missed a chance to move into a three-way tie for ninth place.

Florida goalie Tomas Vokoun made 26 saves in his 500th NHL game.

St. Louis' Chris Mason, making his 16th consecutive start, stopped 30 shots.

The teams split the season series. The Blues won 4-0 at St. Louis on Oct. 25.

Booth, Florida's leading goal scorer with 24, had only one goal in his last 15 games.

His first goal gave the Panthers a 2-0 lead at 13:46 of the first period. He scored on the power play with a backhand rebound from close range after Keith Ballard fired a wrist shot from the point.

Booth again gave the Panthers a two-goal lead at 5:58 of the second period. With the teams skating 4-on-4, he took a pass from Michael Frolik, faked a shot, then skated around Carlo Colaiacovo before beating Mason with a wrist shot to the glove side.

With Florida clinging to a one-goal lead, Booth completed his second hat trick of the season with 2:26 left in the third period, tapping home Richard Zednik's feed on a 2-on-1.

Booth set up Horton's goal, which opened the scoring at 5:32 of the first, with a beautiful backhand pass from the boards. Horton ended up alone on Mason and waited for Mason to go down before flipping a shot over his left shoulder.

Backes got St. Louis on the board at 3:48 of the second after he intercepted a pass in the neutral zone and came in on a 2-on-1. Backes beat Vokoun with a wrist shot that found its way between Vokoun's left arm and his body.

After Dvorak made it 4-1 at 18:15 of the second with a slap shot from the top of the faceoff circle, Backes got St. Louis within two goals with only 13.2 seconds remaining in the second period.

Brad Winchester attempted to stuff the puck in from behind the net and B.J. Crombeen came crashing to the net. With a pile-up in the crease, the puck slid along the goal line before Backes tapped it in.

Boyes made it 4-3 with a power-play goal at 1:52 of the third period.
