The San Diego Padres have officially added left-handed pitcher Robbie Ray to the active roster ahead of Wednesday's game against the Arizona Diamondbacks. In order to make room for him on the 26-man roster, right-handed pitcher Germán Márquez has been designated for assignment. Padres Add Robbie Ray to Roster, Set DebutRay, 34, was acquired by the Padres from the San Francisco Giants in exchange for two prospects ahead of Monday's deadline. His most recent start was against San Diego, when he fired six innings of one-run ball in a Giants win. Manager Craig Stammen knew the team would have some "difficult" decisions to make with the additions of Mize and Ray.
