This season, Rakuten 's Itsuki Murabayashi 's 10th year as a professional, has been a breakthrough year for him, as he won his first batting title, most hit, was named to the Best Nine at third base, and also won his first Golden Glove Award as a third baseman.

He batted .241 last season, but reached his first regulation at-bat and established himself as a short stop regular with a solid defense. In the offseason, he changed his number from '66' to '6'. However, he was called the university's No. 1 short stop at the draft meeting, and Rui Muneyama was selected. From practice games and open games, Soyama protected short stop and Murabayashi often played at third.

In the opening game against Orix on March 28th, Murabayashi started as the sixth batter and third baseman. In games where Muneyama was absent, starting line-up started at short stop, and had two hit in the games against Nippon-Ham on April 9th and Orix on April 13th, and a multi-hit game against Nippon-Ham on April 23rd. At the end of April, his batting average was .349, an eye-opening achievement.

His momentum continued into May, with a batting average of .322 in May, .283 in June, and .308 in July, maintaining a batting average of .300 and putting him in a position to aim for the hitter title. His batting form dropped in September, dropping his batting average below .300, eventually dropping to .281. Still, he hit 144 hit and won the title for most hit.

Even after the regular season ended, he was selected to represent Japan in the "LUXAS Samurai Japan Series 2025 Japan vs. Korea" held on November 15th and 16th, raising hopes that he will make the WBC team. His ability to play not only short stop but also third and second baseman at a high level is also a strength. He was forced to change positions with the addition of Muneyama, but he performed even better than the previous year on both offense and defense, as expected.
