Athletics' Yacksel Rios: Will undergo surgery

Rios (fingers) will undergo a procedure Friday to address his Raynaud's Syndrome, Martin Gallegos of MLB.com reports.

Rios received the diagnosis last week, and it was determined after a visit with a specialist that surgery was the best course of action for his circulatory condition. There's currently no timetable for his return, but more clarity could be available after the operation.
