On the 14th, Orix Buffaloes Buffaloes announced that their developmental pitcher, Kosuke Kawachi, underwent "left leg Lisfranc reconstruction surgery using an artificial ligament" at a hospital in Kobe. This season, his third as a professional, he injured his right knee during the Miyazaki training camp in February. He underwent anterior cruciate ligament reconstruction surgery that same month.

The right-handed pitcher, who joined the team in 2023 as the second overall pick in the draft from Ehime's St. Catherine High School, underwent ulnar collateral ligament reconstruction surgery (commonly known as Tommy John surgery) in his right elbow and was subsequently placed on a development contract in the offseason of 2024. He is scheduled to undergo rehabilitation with the aim of returning to competition after being hospitalized for about a week.
