On the 2nd, Seibu Lions pitcher Chihiro Sumida, who left the game on the 28th against the Rakuten Eagles (Belluna Dome) after being hit in the left forearm by a batted ball, participated in team practice held at his home stadium, Belluna Dome.

On this day, after warming up, he played catch for a few balls at a distance of about 10 meters, and then withdrew to the back of the bench with a trainer.

It has already been decided that the team will compete in the Climax Series (CS) First Stage starting on the 10th. Manager Nishiguchi explained regarding the left-hander's future, "We won't know until the very last minute. There is a possibility (he will pitch in the CS first baseman)." While it depends on the condition of the affected area, which remains significantly swollen, he held out hope for a possible starting appearance in the CS.
