The Swallows announced today that Yoshinori Sato will have his right shoulder cleaned out at a hospital in Yokohama on the 11th. He will most likely require about six months for a full recovery. There is a chance he will miss the season.
Yoshinori has not pitched in an Ichi-gun game since he first complained of shoulder tightness in September 2011. The decision to have surgery was made because he was not making significant progress in his recovery.
