On the 11th, left-handed pitcher Masa Yamamoto, who has a total of 219 wins, joined Nippon-Ham 's first-team Nago camp as a temporary coach.

Greeted by Manager Shinjo at the front of the stadium, Yamamoto smiled and said, "It's only one session, but I'll do my best." Before practice began, he stood in front of the players and said, "I think the pitchers can answer any question. It's temporary, but I'm not asking them to do it, but I hope to add at least one more skill to my repertoire. I look forward to working with you from today."

When announcing the invitation, Manager Shinjo expressed his expectations, saying, "Left-handed pitcher like Miyanishi, Kato, and Yamazaki, who are now over 30, were able to play until they were 50. They need some technique, and they have a baseball brain. I would like them to learn things like how to use the inside pitches and the technique of not sending runner first baseman to second baseman. Also, how to use a screwball. I would like to hear about their dexterity. As for left-handed pitcher, I would like to be the pitching coach for left-handed pitcher."
