TAMPA, Fla. -- The Tampa Bay Lightning are gearing up for their first postseason appearance since 2007.
"Little by little we're building back up," Moore said. "Again, it's no secret, it's all about work and effort. Earning victories and deserving wins."
Tampa Bay would have clinched a playoff berth if Carolina, which beat Washington 3-2 in shootout, had lost in regulation.
"It's for another day," Stamkos said. "We're comfortable with our game right now. Seems like we've got our confidence back. There's a lot of positives."
The Lightning play Pittsburgh, a potential first-round playoff opponent, on Thursday night.
"We know that we've got a good chance of playing each other, so we'll definitely learn from each other," Tampa Bay captain Vincent Lecavalier said. "It's pretty close to playoff time. I'm sure it's going to be a pretty intense game."
"They got a couple of lucky goals," Spezza said. "They played well, but I don't think it's a 5-2 game. We deserved better than that."
Moore made it 2-0 with 12:35 left in the second. Marc-Andre Bergeron's shot went off the end boards and rebounded into the crease, where Moore poked the puck into the net while goalie Curtis McElhinney was trying to control it with his glove.
"I still think I had it covered to begin with," McElhinney said. "Sometimes that's the way it goes."
St. Louis extended Tampa Bay's advantage to 3-0 on his 29th goal of the season 5:48 into the third. St. Louis scored off a pass through the slot from Gagne.
After Spezza scored with 9:57 left, Tampa Bay responded with Moore's second of the game, 1:24 later.
"They just made good on their opportunities," Ottawa coach Cory Clouston said. "Unfortunately we didn't have any puck luck."
Michalek scored a short-handed goal later in the third. Tampa Bay has given up 16 short-handed goals.
Stamkos, who has just four goals in 22 games, scored his 44th this season with 33.9 seconds left. Stamkos also ended a five-game point drought earlier with an assist on St. Louis' third-period goal.

McElhinney, claimed by Ottawa off waivers from the Lightning on Feb. 28, had beaten Tampa Bay twice earlier this month. He never played with the Lightning after being obtained in a trade with Anaheim on Feb. 24. ... Bergeron stopped his 11-game point drought. ... Lecavalier had an assist to extend his point streak to five games (five assists, seven points).
