The Dodgers‘ latest update on the shoulder of Hyun-jin Ryu is not a good one. As Zach Helfand of the Los Angeles Times reports, Ryu sat in the 82 to 83 mph range in his last bullpen session. Manager Don Mattingly says that level was below what the team was comfortable with to continue his progression, with the club preferring instead to give Ryu extra rest. Mattingly acknowledged some concern, though he indicated it is too early to tell whether Ryu will get back on his expected timetable. The Dodgers’ summer trade plans could hinge in large part on Ryu’s health.
