The Pittsburgh Pirates placed Tyler Glasnow on the 15-day disabled list on Sunday morning and recalled A.J. Schugel, who was optioned to Indianapolis yesterday to make room for Glasnow. Usually the waiting period for calling up a player who was optioned is ten days, but that is waived if another player goes on the disabled list. Glasnow left yesterday’s start with right shoulder discomfort. No update on his injury has been given.
