Trea Turner hit two homers, including a go-ahead grand slam in the sixth, and drove in eight runs as the Washington Nationals rebounded from an early nine-run deficit to stun the Miami Marlins 14-12 Thursday night at Nationals Park.

The comeback was the biggest in Nationals history.

The grand slam was the first of Turner's career, and his eight RBIs tied the second most in a game in franchise history.

Turner batted leadoff and Juan Soto added three RBIs from the No. 2 spot, giving Washington 11 RBIs from the top of the order. Turner went 3-for-5 while Soto finished 2-for-4. Matt Adams added four hits for Washington.

Shawn Kelley (1-0) got the win after throwing a scoreless sixth. Sean Doolittle closed it in the ninth and earned his 22nd save.

The Marlins raced to a 9-0 lead in the fourth inning. They scored a run on a first-inning error before a Martin Prado three-run homer sparked a six-run second inning that made it 7-0.

Justin Bour added a two-run homer in the fourth off Washington starter Jeremy Hellickson (nine runs, eight earned, in four innings) that increased the lead to 9-0. However, the Nationals then scored 14 consecutive runs over the next four innings.

Turner hit his first homer of the night, a solo shot, in the fourth before driving in a run on a forceout in the fifth. Soto lined a two-run double in a four-run fifth as the Nationals sliced the lead to 9-5 against Miami starter Pablo Lopez.

Washington added five more runs and took the lead in the sixth -- with Turner once more coming up big.

Daniel Murphy hit a sacrifice fly that made it 9-6, and Turner hit a two-out grand slam off of Adam Conley (2-1). That gave the Nationals their first lead of the game at 10-9.

Conley allowed five runs on just two hits -- thanks mostly to four walks and the grand slam -- in two-thirds of an inning.

The Nationals added four more in the seventh that included a two-run Turner single plus a Soto RBI single, stretching the lead to 14-9.

Miami sliced the deficit to 14-12 when Brian Anderson hit a three-run, eighth-inning homer off Kelvin Herrera, but Washington held on.
