Volquez (6-1, 1.12 ERA) pitched six innings and allowed one earned run on seven hits with two walks and five strikeouts. Volquez has yet to give up more than one earned run over his first eight starts for Cincinnati.

Cincinnati has taken the first two of a four-game series from Florida, which came into the week winners of seven-straight.

In the Reds' second inning, Ryan Freel beat out a two-out single to first base with a headfirst slide as Jerry Hairston Jr. scored the game's first run. Jeff Keppinger followed with a bases loaded walk that scored David Ross.

It proved to be costly plate appearance for Keppinger, who fouled one of Mark Hendrickson's pitches off of his left knee. Keppinger left the game two innings later and X-rays showed a fractured patella that is likely to send him to the disabled list.

It was a 3-0 game in the Florida fifth when a bases-loaded situation yielded just one run for the Marlins. Three-straight one out singles loaded the bases and led to Henley Ramirez's sacrifice fly. A Jorge Cantu walk loaded them again but Volquez struck out Dan Uggla to escape further damage.

In the Reds' fifth, Hairston hit a two-out double to the left field wall and stole third base. After Adam Dunn walked, David Ross dropped a perfect bunt single down the third base line and scored Hairston for a three-run lead.

The Marlins scored a run against reliever Jared Burton with Uggla's seventh-inning, two-out RBI single. Joey Votto got the run back in the bottom half when he led off with a home run to left field off Doug Waechter. Cody Ross homered in the top of the eighth to make it 5-3.
