The Marlins Park home run sculpture still works.

Adeiny Hechavarria’s fourth-inning blast to left field Tuesday night activated it for the first time this season.

And it turned on the team’s offense in an outburst it has desperately needed for the first two-plus weeks of the season.

Hechavarria’s three-run homer highlighted a four-run fourth inning that was followed by a three-run fifth and led to a season-high eight runs and an 8-2 victory over the Nationals in front of an announced crowd of 16,216.

“I was beginning to think the sculpture wasn’t plugged in,” Marlins manager Mike Redmond said. “It’s definitely working now.”

The Marlins (3-11), who had scored only 23 runs through their first 13 games, had two multirun innings and posted another in Monday’s 10-3 loss. They had only two multirun innings in their first 12 games. They also finished with 11 hits, marking only the fourth double-digit hit game this season and first at home.

It was only the fifth time this season the Marlins scored first and took a lead in a game. Every Marlins starter in Tuesday’s game, except Placido Polanco, came in hitting .238 or lower.

Hechavarria, who entered the game hitting .178, crushed a 1-1 pitch from Nationals starter Dan Haren deep to left field for a three-run home run. The drive traveled an estimated 416 feet.

“I felt like I did something big for the team,” Hechavarria said. “You could feel the emotion of joy in the dugout from the players to the managers.’’

Hechavarria, who hit two homers in 41 games played last year with the Blue Jays, had no home runs or RBI this season before Tuesday.

His home run ended a drought of nine games without a home run, tying the franchise record set during the team’s 1993 inaugural season. It also ended a seven-game drought at home that also matched a franchise record and was the longest at home for a team since the Expos opened the season without hitting a homer for seven games in 2004.

“You can’t tell the future, so I don’t know what will happen tomorrow,” Hechavarria said. “But I think this was a key game to show that this is a good team.’’
