Rakuten Eagles outfielder Ryosuke Tatsumi held contract negotiations in Sendai City on the 7th and signed a one-year deal. Following this season, the amount remains undisclosed.

Last off-season, he exercised his domestic free agent rights. It was not until January of the new year that he decided to stay and finished his contract negotiations, but this off-season, he was the first among the core players to complete his renewal. In this, his eighth professional season, he appeared in 137 games and recorded a career-high 15 Home Runs. Reflecting on the season, he said, 'I was sidelined during camp and returned just before the opening, but after that, I was able to run through the rest of the year without any injuries.'

Although the team finished in last place, he expressed his determination to bounce back, stating, "There isn't a huge difference in terms of overall strength. We just need to produce results. Each individual needs to level up. I want to improve every aspect of my own game as well." His right elbow, which underwent cleaning surgery in October, is in good condition, and it is said that there will be no impact on his play from the start of next season. On a signature board, he wrote "Championship" as his goal for next season, in letters far larger than his own name.
