TAMPA—On a night when Steven Stamkos scored his NHL-leading 42nd goal, the Tampa Bay Lightning broke out of a puzzling offensive funk before finishing off the Blackhawks with a little pizazz.Martin St. Louis scored in regulation, then delivered the shootout winner in a 4-3 victory that ended a season-high four-game losing streak.The six-time All-Star spun in front of the net, set himself and fired the puck past goalie Corey Crawford for the only goal by either team in the shootout.Teddy Purcell also scored for the Tampa Bay, helping build a 3-1 lead before the Stanley Cup champions roared back on goals by Patrick Sharp and Jonathan Toews.Dwayne Roloson made 28 saves for the Lightning, then stopped Toews, Patrick Kane and Marian Hossa in the shootout.The loss was the second straight for the Hawls following a season-best eight-game winning streak.Stamkos got Tampa Bay off to a fast start with just his second goal in the last 13 games. St. Louis ended a four-game drought to break a 1-1 tie before Purcell put the Lightning up 3-1 with his first goal in seven games.It was just the second time in 10 games that the Lightning, who fell out of first place in the Southeast Division during its four-game skid, scored more than two goals. A poor first period cost the Blackhawks in a 3-2 loss to Florida that stopped a winning streak on Tuesday night. The Panthers scored three early goals against Crawford, who gave up three more in the first 22 minutes against Tampa Bay.Kane scored in the opening period. Sharp’s 34th of the season pulled the Blackhawks to 3-2. Toews, who had a nine-game points streak stopped against Florida, had assists on the Blackhawks’ first two goals and tied it 3-all with 16:30 remaining in regulation.
