"When the big line isn't going, we found a way," Tampa Bay coach John Tortorella said. "I thought Grats' line was probably our best line."
Gratton, reacquired by Tampa Bay from Florida for a 2008 second-round draft pick in June, has 14 career multigoal games.
"It's always tough to play your former teammates," Gratton said. "It's nice to chip in against any team in the league. Our line has got to help out with the offense a little bit. We got a couple lucky breaks, but I thought it was a solid game by both teams."
Holmqvist has allowed four goals in three games this season, helping the Lightning start the season 3-0 for the just the third time in team history.
"Last year, most of those shots would go in," Florida captain Olli Jokinen said. "I think their goalie played probably the best game since he's been in the league, especially against us."
"That was probably our best game since the start of the season," Florida coach Jacques Martin said. "I think we created some more chances and made some good saves. We just didn't finish at times, but we did a lot of things better."
Tampa Bay took a 2-1 lead when Gratton redirected Paul Ranger's shot during a power play with 9:24 left in the second. Peltonen had tied it at 1 earlier in the period at 4:04.
Gratton put Tampa Bay up 1-0 with a rebound goal at 9:03 of the first. The goal came shortly after Holmqvist made a strong save on Nathan Horton's shot from the low slot.
Anderson stopped Lecavalier twice on breakaways during the final five minutes of the first. He got the start in place of the struggling Tomas Vokoun, who is 0-2 with a 4.54 goals-against-average and an .816 save percentage this season.
Florida had the first eight shots of the third, but Holmqvist was up to the challenge and stopped them all during the period's opening five minutes.
Tampa Bay was credited with 13 blocked shots, and also limited rebound opportunities.
"You need to have a purpose when you go to the net," Jokinen said. "You just don't go there because the coach tells you to go. You have to have that fire in your eyes. You have to think there's going to be a rebound. You have to be ready to put the puck in."
