The NHL's top goal scorer this season scored one early in the third period to break a tie, and Holmqvist made 34 saves to lead the Lightning to a 3-2 victory Saturday night, evening the first-round, Eastern Conference series at 1-all.
Martin St. Louis and Filip Kuba also scored for the Lightning, who will host the next two games of the best-of-seven matchup, starting Monday.
Zach Parise and Jamie Langenbrunner scored for the Devils, who squandered a 2-1 lead late in the second period.
St. Louis tied the game with less than a minute left in the middle frame with a bad-angle goal from along the goal-line that somehow eluded Martin Brodeur.
Lecavalier got the winner and his third of the series by getting behind the Devils' defence and deflecting a shot from the point by Paul Ranger at 1:42 of the third period.
It was then up to Holmqvist to make the lead stand. He came through unlike in Game 1, when he gave up five goals, including three bad ones, on 24 shots in Tampa Bay's 5-3 loss.
Playing in his second career playoff game, Holmqvist came up big, stopping a close-in whack by Brian Gionta at the right post in the final two seconds. He also made good saves on Parise and Paul Martin in the closing minutes.
