The decision on the opponent Softbank Hawks will face in the CS Final Stage (opening on the 14th at Mizuho PayPay Dome) has been postponed. The second game of the first stage was held on the 11th (Belluna Dome), where Nippon-Ham showed their spirit, defeating the Seibu Lions 1-0 to bring the series to one win and one loss.

They finished 11.5 games ahead of the second-place Seibu Lions, securing their first three consecutive league titles since moving to Fukuoka. They were 13 games ahead of Nippon-Ham. Starting this season, new rules for the Climax Series have been introduced, and regardless of which team advances, a 'two-win advantage' (conditioned on a lead of 10 games or more, or the opponent having a winning percentage below .500) will be applied to the Softbank Hawks for the first time. The series will be played as a maximum of seven games, with the first team to reach five wins declared the winner.

For the first time in 60 years, the team achieved a three-peat by winning the season series against every other team in the same league. They finished with 14 wins and 11 losses against the Seibu Lions this season, including a 7-5 winning record at home. Meanwhile, they dominated Nippon-Ham, who they fought for the league title last season, with a record of 18 wins, 5 losses, and 2 draws this season, including a franchise-first 7-game winning streak from the start of the season. In particular, at their home stadium, Mizuho PayPay, they went 11-1, which also included a 7-game winning streak from the start of the season.
