Following an 8-1 loss to Sammy Sosa and the Cubs, the Marlins optioned right-handed reliever Rafael Medina to Triple-A Calgary and placed right-handed reliever Archie Corbin on the 15-day disabled list with a sore pitching elbow. Left handed rookie Brent Billingsley was recalled from Calgary. Alex Fernandez will be activated today and start tonight against the Cubs.
