Martinez (shoulder) was placed on the 10-day injured list Monday.
This was expected. Martinez, who has been sidelined for most of spring due to a shoulder issue, recently resumed his throwing program. Pete Wickham of MLB.com reports that manager Mike Shildt estimates Martinez is "a month to a month and half away, to where we can evaluate where he is and how we want him to progress." This timeline makes it seem like a return sometime in May would be a best-case scenario. He will need to go on a rehab assignment before getting activated and occupying either a rotation spot or a high-leverage relief role.
