CINCINNATI -

Devin Mesoraco hit his third grand slam of the season and drove in six runs, and the Cincinnati Reds salvaged the finale of a three-game series against the Miami Marlins with a 7-2 win on Sunday.

Brad Hand walked Todd Frazier with the bases loaded in the fifth to break a 2-all tie. Mesoraco followed with his second homer of the game and 20th of the season, a 371-foot drive into the left-field seats.

Mesoraco leads all major league catchers in home runs and the National League in grand slams. He is 6 for 7 (.857) with the bases loaded and is the sixth player in Reds' history to hit three slams in one season -- the first since Chris Sabo in 1993.

The fifth-inning outburst gave Johnny Cueto (14-6) some breathing room. In eight innings, he allowed five hits -- two homers -- with two walks and nine strikeouts.
