Leadoff man Chris Coghlan's uneven season continued with a two-hit game in Wednesday's series finale in Arizona. Before that he was 0-for-11. Before that he had a three-hit game.

The left-handed hitting Coghlan went 9-for-39 (.231) on the road trip and is batting .237 with a .301 on-base percentage. Manager Edwin Rodriguez batted him seventh on Monday against Diamondbacks lefty Joe Saunders, but he's committed to keeping Coghlan atop the order.

"The thing with Coghlan is he should be our leadoff guy for the entire season," Rodriguez said. "I'm looking at it this way. He's struggling against left-handed pitchers, but in the long run he should be our leadoff guy. He needs to find a way to get out of that slump. … In the long run, if we want to win Coghlan has to be able to hit left-handers."

President of Baseball Operations Larry Beinfest is confident the Marlins will start getting steadier production from the 2009 National League Rookie of the Year.
