Softbank Hawks 's Ozeki showed steady progress ahead of the opening game. He started against Yakult (Mizuho PayPay) and pitched four innings, allowing three hit and two runs (one earned) while strike out. This was his first appearance on the mound in an external game this season, and he showed great confidence.

Last season, he achieved his first title with the highest winning percentage, with a record of 13 wins and 5 losses. He was particularly unbeatable at home, with a record of 9 wins and 0 losses and ERA of 1.30. Seeking further improvement, he has been working on a windup pitching style since this season.

Although he ceded the opening pitcher to Uwasawa, manager Kokubo had placed great trust in him since spring training, saying, "No matter what condition he's in, he's in the rotation." He continues to adjust with the awareness that he will be a key part of the starting rotation, stating, "I'm working to have my sharpness, control, and velocity all in place by the start of the season."
