After Adam Fantilli tripped Matthew Tkachuk on a breakaway 48 seconds into overtime to put Florida on the man-advantage, Tkachuk sent the puck across to Reinhart on the goal line on the left side, and he lifted a shot over Elvis Merzlikins’ shoulder on the short side.
Reinhart also had an assist, Sam Bennett scored, and Sergei Bobrovsky made 30 saves for the Panthers (33-29-3). Defenseman Mike Benning got the secondary assist on the game-winner in his NHL debut.
Fantilli scored, and Merzlikins made 19 saves for the Blue Jackets (33-21-11), who extended their point streak to eight games (4-0-4).
Columbus outshot Florida 14-3 in the first period and took a 1-0 lead at 13:01 of the second. After a Panthers turnover in the offensive zone, Mason Marchment picked up the puck and led a Blue Jackets rush before feeding Fantilli, who scored with a wrist shot from the right face-off circle.
The goal came moments after Bobrovsky stopped Kirill Marchenko with his pad after being tripped up by the stick of a teammate.
Bennett tied it 1-1 on the power play at 1:28 of the third period. Reinhart took a hard shot from the left side that went off the post, and Bennett knocked in the rebound from the right side.
The Panthers played without forwards Carter Verhaeghe (tightness) and Anton Lundell (rest). Benning entered the lineup in place of defenseman Uvis Balinskis (lower body).
