Los Angeles Dodgers star Yoshinobu Yamamoto appears to be off the market -- the ace was spotted moseying around Beverly Hills with Japanese model Niki Niwa.
The new World Series champ hit Rodeo Drive with Niwa -- who also starred on the popular reality show, "Terrace House" -- earlier this week ... when TikTok content creator Jack Banana ran into the two potential love birds.
26-year-old Yamamoto and Niwa, 28, seemed to be mid-shopping spree ... which is well deserved after helping bring home a Commissioner's Trophy to the City of Angels.
