9:36PM: Jack McKeon, 80, is expected to be named the Marlins' new manager, tweets Buster Olney of ESPN.com.
11:52AM: Bobby Valentine is also being considered by the Marlins as well, tweets Ken Rosenthal of FOX Sports.
11:30AM: In addition to Hyde, the Marlins are considering 80-year-old Jack McKeon as a candidate for interim manager, tweets Olney.
10:35AM: Marlins skipper Edwin Rodriguez has resigned, according to Clark Spencer of the Miami Herald (via Twitter). Bench coach Brandon Hyde will manage the team this afternoon in Tampa Bay as the club begins its search for an interim manager.
Rumors have swirled about Rodriguez's job status this season as the Fish have floundered. The Fish have long coveted White Sox manager Ozzie Guillen and Ken Rosenthal of FOX Sports recently reported that the team was even looking at Bobby Valentine.
Florida has lost 18 of their last 21 games and earlier this month fired hitting coach John Mallee in an effort to shake things up. The Marlins are at the bottom of the NL East, 12.5 games back of the first place Phillies.
Rodriguez was hired on a full-time basis in November. The 50-year-old finished 2010 as the club's interim manager after Fredi Gonzalez was fired.
