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.
