The Mets designated Short for assignment Thursday.
Short was selected to the active roster Friday to provide some extra infield depth during the final weekend before the All-Star break, but he'll now lose his spot to make room for Marcus Semien's (hip) return from the IL. Short went 0-for-6 with a walk during his three-game stint with the Mets and is likely to spend most of the second half working as organizational depth in the minor leagues.
