Lotte's professional baseball player Masuda got involved in a locker-room incident, causing him to suffer a fracture after punching a locker. The incident occurred at the team's clubhouse following a recent game. It remains unclear what triggered Masuda's actions, and the management of Chiba Lotte Marines is currently looking into the issue.

In Japan, such incidents are taken very seriously by sports teams, fans, and the public. Not only for the physical health of the athletes, but this issue is also crucial for the image of the team and its related organizations. Japan's culture of respect and collective responsibility often leads to heightened sensitivity toward such actions, and Masuda could face disciplinary actions.

In the US, similar incidents also make headlines. Athletes are expected to uphold sportsmanship on and off the field. Such incidents might result in suspensions, fines, or other forms of discipline depending on the severity.
