Chris Coghlan's production has fallen dramatically as he's dealt with knee and shoulder injuries since winning Rookie of the Year in 2009.

On Friday, the Marlins decided Coghlan's problems were too severe to fix in the big leagues and optioned the center fielder to Class AAA New Orleans.

Dewayne Wise, signed Wednesday, was called up after playing two games for the Zephyrs and was in the starting lineup Friday against the Rays. Wise was with the Marlins during spring training.

Coghlan, who has been the Marlins' primary leadoff hitter, has a .230 average with a .296 on-base percentage. Since hitting .321 and being named the National League's top rookie two seasons ago, Coghlan is hitting .252.

Marlins manager Edwin Rodriguez said Coghlan needs to work on his swing.

"We all know he's a way better hitter than he's been showing," Rodriguez said. "If he goes back to basics with less pressure I think he'll be fine. And whenever he's fine then he come back here and helps us."

The problem, according to Rodriguez: "Swinging at bad pitches. I think he doesn't have the confidence to take close pitches like he did last year."

Rodriguez said Coghlan took the news hard. Coghlan is from Tarpon Springs, which is just north of the Tampa area and he typically has a large contingent of friends and family at the games against the Rays.

"He's the Rookie of the Year and he knows he belongs here," Rodriguez said. "He's just having a bad start. You have to take into consideration he lost a lot of time in spring training. I think whenever he started playing the last week of spring training he never got into a groove offensively."
