Pirates director of sports medicine, Todd Tomczyk, reported that Ronny Simon had shoulder surgery roughly four months ago.
Simon was non-tendered by the Pirates at the end of November, which is less than four months ago, and means the Pirates knew that at the time of that decision. He was then re-signed to a minor league deal in December, which cleared a spot on the 40-man roster. Simon is already swinging in the cage and could get into game action in early April, but he will likely start the season on the injured list.
