Medina was optioned to Triple-A Indianapolis on Saturday.
Medina is just 25 years old and was an interesting prospect in the lower minors, but his star has faded to the point that he was designated for assignment by the Phillies over the winter. The Pirates don't have a particularly tough rotation to break into, but his 5.05 ERA in 17 Triple-A starts last year suggests he has more work to do before making a push for a starting role in the majors.
