The Miami Marlins dropped the middle game of a three-game series to the Pittsburgh Pirates on Wednesday by a final of 7-3.

Tom Koehler gave up four runs in the first inning and then nothing more in his next five innings. The damage was done however as Koehler was tagged with his ninth loss of the season. The right-hander walked four and gave up five hits while striking out four.

After Chris Hatcher found himself in trouble as the first man out of the bullpen, Mike Dunn entered. The left-hander didn't fare much better however and went on to allow both of Hatcher's inherited runners to score. Dunn also allowed a run of his own along the way.

Miami scored once in the first and added two more in the second inning on a two-run home run from Christian Yelich. The left-fielder now has nine home runs on the season. In the first inning, Jeff Baker brought home a run on an infield single.

Giancarlo Stanton struggled in an 0-4 day and his average now sits at .290 on the year. Casey McGehee's recent offensive problems continued with a 1-3 day. The third baseman is hitting under .100 in August after nearly a week of games.

Brian Flynn will get the ball for Miami on Thursday as the Marlins try to take the rubber match and win the series. Flynn is replacing Jarred Cosart who is being forced to miss the start with a sore oblique.
