The Tampa Bay Lightning looked much more like its championship-caliber form in a 5-1 win against the Florida Panthers in Game 3.

A Lightning power play was negated after the second-period horn when Anthony Cirelli was called for roughing. But Tampa Bay opened the third by scoring in the final seconds of 4-on-4 play (before Florida went on the power play) on Jake Guentzel’s third goal of the series just 21 seconds into the third period.

After their first two games of the first-round Stanley Cup playoff series against the defending-champion Florida Panthers, the Tampa Bay Lightning were on their heels and on the ropes, having dropped both games at home to the Panthers.
