Los Angeles Dodgers star Shohei Ohtani and his wife Mamiko Tanaka are expecting their first child.

"Can't wait for the little rookie to join our family soon!" Ohtani wrote Saturday on his Instagram.

The Instagram photo announcing the pregnancy also featured Ohtani's dog, Dekopin, who is also nicknamed Decoy.

Ohtani first announced his marriage in February two months after signing a 10-year, $700 million deal to join the Dodgers.

"Not only have I began a new chapter in my career with the Dodgers but I also have began a new life with someone from my Native country of Japan who is very special to me and I wanted everyone to know I am now married," Ohtani wrote on Feb. 29 in an Instagram post.

His wife was later identified as Mamiko Tanaka, who played for the Fujitsu Red Wave in the Women's Japan Basketball League during the 2022-23 season.

Mamiko Tanaka made several public appearances with the Dodgers star before joining him for his team's World Series victory parade in November.

Ohtani led MLB with 134 runs and paced the NL with 130 RBI on his way to a second consecutive MVP award before helping the Dodgers win a championship in 2024.

He could play an even bigger role as the club looks to defend its title next fall. Ohtani is expected to return to pitching for the first time since undergoing elbow surgery in September 2023.

Ohtani underwent left shoulder surgery following the Dodgers' World Series win but is expected to return in time for spring training, according to the team.
