The Marlins acquired right-handed reliever Juan Acevedo from the Colorado for AAA infielder Josue Espada. The 31 year old Acevedo was 0-2 with a 5.63 ERA in 38 appearances with the Rockies. The Mexican born Acevedo will provide much needed veteran relief in the bullpen and will likely be the right-handed setup man for Antonio Alfonseca. Gary Knotts was sent down to AAA to make room for Acevedo. After declaring himself pain-free, Preston Wilson joined AAA Calgary in New Orleans for a series against the local Zephyrs. Wilson has been out since June 30 due to an injury in his left thumb and the tragic death of his son. He is expected back in Florida by the end of the week.
