Ryu (glute) is headed to the 15-day DL, Ken Gurnick of MLB.com reports. Manager Don Mattingly had previously indicated that Ryu would likely miss one start as a result of the glute injury, but he'll miss at least two turns after an MRI revealed a Grade 1-2 strain. The team will re-evaluate Ryu in the coming days, with a timetable likely to be disclosed shortly thereafter. Kevin Correia will take Ryu's spot in the rotation starting Tuesday.
