The Florida Marlins have fired manager Fredi Gonzalez and two coaches.
Edwin Rodriguez, manager at Triple A New Orleans, has been named interim manager.
"We can believe we can do better and be better," owner Jeffrey Loria said in a written statement. "Everybody knows how I feel about winning. That’s the reason we’re making this change."
Loria said before the season that he had high expectations for the Marlins, who improved to 34-36 with Tuesday night’s victory over the Orioles and are in fourth place in the National League East.
Also let go were hitting coach Jim Presley and bench coach Carlos Tosca.
"We have a long season in front of us and plenty of time to turn things around," Loria said.
Gonzalez has managed the Marlins since 2007 when he took over for Joe Girardi, who was fired after one season. Gonzalez has a record of 276-279 with the Marlins and finished with winning records in 2008 and 2009.
