On the 25th, Seibu Lions announced that pitcher Yuta Kuroki (31) underwent a right shoulder arthroscopic cleaning surgery at a hospital in Tokyo on the 20th.

It is expected to take three months for him to return to action in order to improve his condition.

The right-handed pitcher joined Seibu Lions as a development player last season after playing for Orix Buffaloes and Nippon-Ham. After being registered as a regular player in March, he pitched in 29 games, recording one win, one loss, three hold, and an ERA of 3.38.
