The Lightning keep pumping away but the well continues to come up dry. In a familiar theme from the past month, Tampa Bay had a strong showing only to fall short in a 4-3 loss to the Penguins on Monday night at CONSOL Energy Center. The Lightning received a pair of goals from Steven Stamkos and one from Tom Pyatt, but third-period goals by the Penguins’ dynamic pair of Evgeni Malkin and Sidney Crosby proved to be the difference as Pittsburgh rallied from a one-goal deficit after 40 minutes. Tampa Bay, meanwhile, lost for the fifth consecutive game and dropped its sixth in the past seven. “At some point, playing well is probably not enough. We need to get results and we need to get them quick,’’ captain Vinny Lecavalier said. “We are doing a lot of good things, we are just not getting points. It’s disappointing but we have to find a way to push harder.’’ The Lightning also lost goaltender Mathieu Garon, who left the game with an unspecified lower-body injury early in the second period, after he stopped 12 of 13 shots. Anders Lindback took the loss in relief, making 16 stops in his first appearance since Feb. 24. Tampa Bay looked in control for a good portion of the game, turning around a first-period deficit with a goal by Stamkos 20 seconds after Garon was injured to tie the game at 1 at 2:39 of the second period. Pyatt then gave Tampa Bay a 2-1 lead as rookie Ondrej Palat made a strong play down low to protect the puck before getting it out front where Nate Thompson’s turnaround shot caromed off the face of Pyatt and into the net at 11:59. But a turnover by Eric Brewer just inside the Lightning blue line led to a highlight-reel goal by Malkin, making his first appearance after sitting out four games with a concussion. Malkin cut around Matt Carle 5:38 into the third and fired the puck past a helpless Lindback.
