Ryu (shoulder) said he is "optimistic" he'll be ready for the playoffs after a successful bullpen session Sunday, MLB.com's Ken Gurnick reports. Ryu's next step would be to throw a simulated game, which could happen as early as Wednesday of this week. Provided he emerges from that workout free of setbacks, manager Don Mattingly will likely pencil in the 27-year-old lefty into his playoff rotation. He'd likely be the No. 3 starter, behind Clayton Kershaw and Zach Greinke.
