Shohei Ohtani and his wife Mamiko Tanaka are expecting their first child.

The Los Angeles Dodgers superstar announced his wife’s pregnancy on Instagram on Saturday, posting a photo of baby clothes and shoes underneath his dog Decoy.

In February, Ohtani announced that he had gotten married and revealed the identity of Tanaka, a former professional basketball player, in March. He’s coming off a season in which he won NL MVP, became the first player in MLB history to hit 50 home runs and steal 50 bases and helped lead the Dodgers to a World Series title.
