The Marlins outrighted Astudillo to Triple-A Jacksonville on Wednesday.
Astudillo looks like he'll stick around in the Miami organization after he went unclaimed when he was exposed to waivers a few days earlier. Before losing his spot on the Marlins' 40-man roster, Astudillo appeared in 17 games with the big club and slashed .270/.289/.351 across 38 plate appearances.
