Shohei Ohtani punched his ticket to the playoffs for the first time in his career ... and the Japanese superstar partied like it on Thursday -- commemorating the moment with his Dodger teammates, wife and adorable pup after winning the NL West championship.
Los Angeles secured its 11th division title in 12 seasons after a 7-2 win over the San Diego Padres ... and after taking some family selfies with Mamiko and Decoy, it was time to take an alcohol shower with the squad.
It was the first locker room celebration of Ohtani's career -- he never sniffed the postseason during his six seasons with the Angels -- so naturally, he committed a party foul by not sporting protective goggles for the boozy bash.
