MIAMI (AP) -- Rookie J.T. Realmuto drove in six runs, including five in a franchise record-tying 10-run sixth inning, which helped the Miami Marlins complete a two-game sweep in a series between last-place teams by beating the Boston Red Sox 14-6 Wednesday.
Realmuto hit an RBI single in the sixth to put the Marlins ahead 5-4, and then hit his first career grand slam later in the inning to make the score 14-4.
He's the first Marlins player to drive in five runs in an inning. It was the second time the Marlins reached double figures in runs in an inning -- they scored 10 times at Arizona in 2009.
Boston's David Ortiz drove in three runs with two homers, giving him 25 this season. It was his 48th multi-homer game and second of the year.
Realmuto also drove in a run with his sixth triple, the most by a rookie catcher since Carlton Fisk of the Red Sox in 1972, according to STATS. Needing a double in the eighth to hit for the cycle, he struck out.
The only catcher with more than six RBIs in a game against the Red Sox was Yankees Hall of Famer Yogi Berra in 1957, according to STATS.
Red Sox manager John Farrell was back in the dugout after he missed Tuesday's game recovering from hernia surgery.
Ichiro Suzuki drove in three runs with a single and a triple for Miami. Suzuki nearly tripped over Ortiz at first base running out a two-run triple in the sixth.
It was Suzuki's first multiple-RBI game since April. The 41-year-old outfielder is batting .253 and has 2,912 career hits.
Teammate Dee Gordon drove in two runs with his second homer of the year and a sacrifice bunt. He added an infield single in the sixth, one of the Marlins' 10 hits in the inning off Eduardo Rodriguez, Ryan Cook and Robbie Ross Jr.
Rodriguez (6-5) allowed eight runs in five-plus innings. Rookie Kyle Barraclough (1-0) pitched 1 1-3 scoreless innings for his first major-league victory.
The teams came into the series with the worst records in their leagues. The Marlins won their third in a row.
The afternoon game drew a crowd of 26,041, with more than half rooting for the Red Sox.
Marlins rookie Adam Conley, making his second career start, was helped by three double-play grounders but still allowed four runs in 4 2-3 innings.
Red Sox: OF Hanley Ramirez will be examined by a doctor Thursday when the team returns to Boston to determine whether further tests are needed on his sore left foot. ... RHP Rick Porcello (sore right triceps) is scheduled to make two rehab starts, beginning Saturday for Class-A Lowell.
Marlins: OF Christian Yelich (bruised right knee) was held out of the starting lineup for the second game in a row but was available.
The Red Sox begin a 10-game homestand Friday when Joe Kelly (4-6, 5.96) starts against Seattle's Mike Montgomery (4-4, 3.25).
The Marlins embark on a six-game trip Friday in St. Louis. Their starter hasn't been announced. The Cardinals swept three games at Marlins Park on June 23-25.
