Nippon-Ham, who lost the first game, won the second game to tie the series at one win and one loss. In the three-game post season and the first stage of the CS, this marks the 22nd time a series has been tied at one win and one loss, following Nippon-Ham in 2024. In the previous 21 instances, the team that caught up to a one-win, one-loss tie has a record of 6 wins and 15 losses in the third game, a winning percentage of .286. This is the fifth time for Nippon-Ham, following 2004, 2015, 2018, and 2024. Of the past four times, they only advanced in 2024.

Nippon-Ham achieved a 1-0 win over the Seibu Lions. This marks the 11th time in history that a 1-0 win has occurred in the PO or CS, the first in two years since The Giants played DeNA in Game 5 of the 2024 Final Stage. For the club, this is the third time, following the game against Lotte in Game 1 of the 1981 PO and the game against the Softbank Hawks in Game 2 of the 2006 Second Stage. With three 1-0 wins in the PO and CS, they have surpassed DeNA, who were tied at two, to hold the record for the most alone.
