David Samson said the Marlins are still trying to figure out how to plug the leaks in the park's 8,000-ton retractable roof and stop the grass in the outfield from dying, The Miami Herald reported Wednesday.
Samson blamed showers in April for making it necessary to close the retractable roof more often than they expected and said the grass decay was due to a lack of sun.
The Marlins have already replaced the turf in right field and there's a chance they might have to redo all the park's sod.
The team hits the road on Tuesday for nine games in San Francisco, San Diego and Houston.
