Santiago (back) was transferred to the 60-day DL on Friday.
This does not impact when Santiago will return to the big-league rotation, as he will be eligible in the coming days, it simply opens up a spot on the 40-man roster for Niko Goodrum, whose contract was selected as a corresponding move. Santiago is expected to make another rehab start for Triple-A Rochester on Sunday and could return to the rotation at some point in September.
