Ryusei Terachi and Atsuki Tomosugi had the most appearances on the team.

This season was a highlight for the young players. Second-year high school graduate Ryusei Terachi played in a team-high 116 games. He made the opening day roster for the first team, and on April 4th against Hokkaido Nippon-Ham Fighters, he made his first start starting line-up of the season. On April 18th against the Tohoku Rakuten Eagles Eagles, he hit two Home Run runs, including his first professional Home Run.

Terachi continued to produce solid results in the first team, hitter fourth in the game against Fukuoka Softbank on July 17th and recording multiple hit. Towards the end of the season, he mainly played as DH due to discomfort in his right elbow, but he still made his presence felt with a batting average of .256, Home Run, and 33 RBI.

In his third year Atsuki Tomosugi also played in 116 games, matching Teraji's record. In May, he recorded 14 At Bat 45 hit for a batting average of .311, and on August 31st, he hit his first professional home run against Fukuoka Softbank. However, his final Home Run average was a disappointing .230. He showed his characteristic solidity in defense at shortstop, and was seen helping his teammates on many occasions, so we hope that he will improve his hitting consistency next season and contribute both offensively and defensively.

Draft pick #1, Misho Nishikawa, becomes the team's fielder to win Rookie of the Year in 28 years.

Draft pick number one, Misho Nishikawa, earned a starting line-up on opening day and immediately recorded his first professional hit and RBI. In April and May, his monthly batting average dropped to the .100s, forcing him to adjust in the minor leagues, but in July and August, his monthly batting average exceeded .300 in both months. On July 30th, in a game against Tohoku Rakuten Eagles, he hit his first professional Home Run. He continued to be starting line-up until the end of the season, reaching the required number of plate appearances despite being a rookie. He recorded a batting average of .281 and a league-leading 27 doble, greatly leading the offense.

Furthermore, he recorded a league-leading 9 assists as outfielder, truly excelling in both offense and defense. He became the fielder in the team's history to win the Rookie of the Year award in 28 years, since Makoto Kosaka in 1997.

The performances of players like Daito Yamamoto, who hit double-digit Home Run, and Eito Takabe were also impressive.

This season, fifth-year player Daito Yamamoto has played in a career-high 107 games. Although he only played in 5 games for the first team last season, Yamamoto had high expectations for his power, having won two titles in Eastern League, Home Run and batting. He hit his first professional Home Run on April 16 against Hokkaido Nippon-Ham Fighters, and then hit back-to-back home runs on June 15 against the Tokyo Yakult Swallows and on July 5 against Orix Buffaloes Home Run, marking 10 Home Run in the first half of the season.

He was selected for the "Mynavi All-Star Game 2025" for the first time through the Plus One vote, but struggled in the second half of August, with a monthly batting average in the Home Run and only one home run. Nevertheless, his 11 Home Run were the second highest on the team, and it can be said that he has emerged as a power hitter.

　Eito Takabe played in 111 games, batting .286 with a team-leading 20 stolen base bases. Last season, he was sidelined mid-season due to injury, but this season, despite a period of adjustment with the minor league team in July, he played in over 100 games for the first time in two years. In particular, his monthly batting average exceeded .300 from August onwards, showing improved form towards the end of the season. We can expect him to continue to be a key hitter in the top of the batting order next season, giving the team momentum.

　Ryusei Ogawa also steadily improved his performance as the season progressed. Although he played in 87 games this season, fewer than last season (119 games), he produced results even with fewer at-bats from June onwards. His batting average dropped to .192 in August, but he had a strong performance in September and October with 21 At Bat in 58 hit for a batting average of .362. He finished the season with a batting average of .264.

A season in which mid-level and foreign players struggled

While young players like Nishikawa and Teraji showed promise, this season was also one in which players who contributed to the team's A-class finish last season struggled.

​Toshiya Sato, who recorded a batting average of .278, fourth in the league last season, and won his first Best Nine award, started as starting line-up in the opening game, but struggled this season, batting .207 in 68 games. Shogo Nakamura, who had played in over 100 games for seven consecutive years, was also affected by a back injury and only played in 20 games this season.

In his second year with the team, Soto hit a team-leading 13 Home Run, but his batting average was only .230 in 102 games. This was a disappointing result compared to last season, when he played in 132 games (batting average .269, Home Run). Polanco 's batting performance was poor from the start of the season. He underwent surgery on his right shoulder in late July and ended his season early, playing in 39 games with a batting average of .201 and Home Run.

Manager Yoshihito Yoshii, who led the team for three years, will step down at the end of this season, and Saburo will take over as the new manager. Can he bring a fresh new look next season by strengthening the team's batting lineup?
