The Pirates selected the contracts of four prospects Tuesday, protecting them from the Rule 5 draft in December.
Catcher-utilityman Endy Rodriguez, third baseman-utilityman Jared Triolo and right-handed pitchers Mike Burrows and Colin Selby were all added to the roster. To make room for them, catcher Tyler Heineman and pitchers Jeremy Beasley, Junior Fernandez and Manny Bañuelos were designated for assignment.
More to come.
