Mattingly said the doctor determined no more tests were necessary. In addition, Mattingly said it "sounds like" Ryu was pain free on Monday, so now he'll just start a throwing program.
"With everything, doc felt good, didn't need anything, just let him start working there and moving forward," Mattingly said.
Ryu said earlier that he dealt with a similar issue pitching in Korea three years ago and was doing much better in just 10 days. Plus, he said on Friday that the shoulder already felt improved from where it was before.
