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.
