The Tampa Bay Lightning suffered their first loss of the season in Ottawa on Saturday despite numerous pushbacks in a weekend matinee.

The home team never trailed in the 5-4 victory at Canadian Tire Centre after a 5-on-3 power play in the first two minutes of the game led to a goal by the Senators’ Drake Batherson for a 1-0 lead. Ottawa led 2-0 late in the first period before Nikita Kucherov scored his seventh goal of the season to get the Lightning on the scoreboard.

Kucherov’s goal is the most in franchise history through the first four games of a season. Tampa Bay forwards Nick Paul and Anthony Cirelli connected to tie the game in the opening frames of the second period, marking the start of what was a chaotic middle period.

Ottawa regained the advantage, 3-2, less than three minutes after Paul’s goal, but Jake Guentzel helped Tampa Bay erase a deficit for the third time in the game on his first goal as a Bolt in the closing minutes of the second period.

A late penalty led to Ottawa regaining the lead on a Brady Tkachuk power-play goal before the end of the second.

A short-handed goal by Noah Gregor extended the Senators’ lead to 5-3 in the third period before Lightning forward Mitchell Chaffee got the visitors within a goal of Ottawa by deflecting a pass from defenseman Nick Perbix.

Tampa Bay, now 3-1-0 this season, plays in Toronto on Monday.
