Miami Marlins slugger Giancarlo Stanton is expected to begin a rehab assignment Tuesday at Class A Jupiter.

Stanton, who is targeting a return to Miami's lineup on Friday, was scheduled to play Monday but inclement weather forced a postponement until Tuesday.

The 25-year-old Stanton has been sidelined since he suffered a fractured hamate bone in his left wrist. He was expected to miss four-to-six weeks after undergoing surgery on June 28.

Signed to a 13-year, $325 million contract in the offseason, Stanton was leading the majors in home runs (27) and RBIs (67) at the time of his injury. He still tops the Marlins in both of those categories.

Marlins right-hander Jarred Cosart, who is making his way back from an inner ear problem, is expected to throwing 75-80 pitches in a start for Jupiter on Tuesday.
