Wennberg made it 2-0 at 8:31 of the second when he one-timed Jonathan Huberdeau's pass on a 2-on-1. Wennberg scored in a third straight game, and Huberdeau became the first player to have 300 assists for the Panthers.
Point made it 2-1 with a power-play goal at 10:55 before Ekblad answered on the power play with a slap shot from the left face-off circle to make it 3-1 at 12:54.
Verhaeghe, facing the Lightning for the first time since helping them win the Stanley Cup last season, extended the lead to it 4-1 at 14:55 when his centering pass bounced in off the skate of Tampa Bay defenseman Erik Cernak.
Point made it 4-2 at 54 seconds of the third period with a second power-play goal, shooting over Bobrovsky from a sharp angle.
"We competed harder and got more physical in that third period, so we need to take the positives from that and bring it over into the next [game]," Point said. "We showed we wanted the puck and started winning some battles. That's a great hockey team over there, and we have to be ready for the next one. They exposed us with their speed, and we have to try to counter that and come ready to play."
Brett Connolly scored into an empty net with 1:00 left for the 5-2 final.
"It's definitely a big win for us," Bobrovsky said. "Tampa is a really good team. They're really balanced throughout the lineup. But I thought we played better than them tonight. We played all zones. We played great defensively, we played great offensively. It's a well-deserved win for us and we move on. ... We have to enjoy it tonight and prepare for the next game against them. We're going to see a different team. It's going to be even more interesting to compete against them next game."
NOTES: Lightning forward Anthony Cirelli (undisclosed) left the game with 8:34 remaining in the third period. "It didn't look great when he came off, but we'll know more later," Cooper said. … Point has scored 11 points (four goals, seven assists) in a seven-game point streak. ... Huberdeau's 15 points (four goals, 11 assists) are tied for the most through the Panthers' first 11 games of a season (Scott Mellanby, 1995-96). He has played 547 games for Florida.
