On the 15th, Orix Buffaloes announced, as previously reported by Sports Hochi, that pitcher Shumpeita Yamashita (23) underwent ulnar collateral ligament reconstruction surgery in the United States. While the recovery period has not been disclosed, a return this season is now unlikely. The team acknowledged the 161 km/h right-hander's desire to return in about a year, which is faster than typical Tommy John surgery, and showed understanding for the surgery being performed in the United States.

In his sixth professional season, he was sidelined just before the opening due to a right elbow injury. He resumed throwing in April, but his condition did not improve. Manager Kishida promised, "I believe he will definitely recover. He will recover completely and come back even better. We will all support him so that he can return and perform well."
