Ryu (shoulder) will be throwing a bullpen session in the next couple days, the Los Angeles Times' Dylan Hernandez reports. He could begin throwing bullpen sessions as soon as Sunday, which would be a huge step in his recovery. After throwing several sessions the Dodgers may be able to begin to map out a plan to send him on a rehab assignment. A late-May/early-June return seems like the best estimate at this point. Scott Baker will be starting Sunday in Ryu's rotation spot with the Dodgers.
