Jake Marisnick belts grand slams in back-to-back innings

      While the Marlins were losing their ninth straight on Thursday, Jake Marisnick was unleashing up in the Florida panhandle, belting two grand slams in back-to-back innings for Double A Jacksonville. This qualifies as reason for hope for the punchless Marlins.

       Not that Marisnick, one of the organization's top prospects, is regarded as a big power guy. He's averaged about one homer for every 41 at bats so far in his minor league career. But it's a sign of promise for the Marlins, who are banking on Marisnick and others to turn the franchise around in years to come.

       As for clubbing grand slams in back-to-back innings, it's happened six times in the majors, most recently by Josh Willingham in 2009 when "Hammer" was with Washington. Nobody tops Fernando Tatis, though. Tatis connected on two grand slams in the same inning for the Cardinals in a 1999 game.
