Habs battle back with three third period goals to beat sagging Lightning Brendan Gallagher broke a tie with Montreal's third goal of the third period, and the Eastern Conference-leading Canadiens rallied to beat the Tampa Bay Lightning 4-3 on Saturday night. The Canadiens pulled within 3-2 on Brian Gionta's power-play goal 3:49 into the third, and Alexei Emelin tied it at 7:33. Gallagher then put the puck past Cedrick Desjardins from in-close to give Montreal a 4-3 lead with 7:57 to play. Montreal also got a goal from Tomas Plekanec and two assists from Michael Ryder as the Canadiens won for the third time in a five-game trip that has one game remaining. Steven Stamkos scored his 19th goal, and Martin St. Louis had two assists for the Lightning, who have lost seven of eight. Sami Salo and Ryan Malone had the other Tampa Bay goals. Stamkos put the Lightning ahead 1-0 when the centre beat Carey Price from the slot off a pass from St. Louis at 5:30 of the second. St. Louis has seven assists and nine points during a six-game point steak. After Plekanec scored 7:38 into the second, Salo gave Tampa Bay a 2-1 advantage just 37 seconds later. Malone made it 3-1 on a power-play redirection with 7:40 left in the second.
