The news about the 29-year-old Japanese player's record-breaking contract has dominated headlines across the United States, including the front page of the Los Angeles Times.
According to US media, the 10-year contract — worth 700 million dollars — is the largest by total value in the history of professional sports.
The Dodgers have yet to make an official announcement, but team catcher William Smith welcomed the Ohtani deal on a radio program.
"No doubt, we got better as a team yesterday," Smith said. He added that he and his teammates are looking forward to playing with Ohtani.
Ohtani says he'll speak more about the move at an upcoming news conference.
Ohtani pledges to give it his all
Ohtani on Saturday posted an image of the Dodgers' team logo on his Instagram account.
In the post, he apologized for taking so long to make a decision. Ohtani also expressed his gratitude to everyone involved in the Los Angeles Angels organization and his fans.
He added, "To all Dodgers fans, I pledge to always do what's best for the team and always continue to give it all to be the best version of myself."
"Until the last day of my playing career, I want to continue to strive forward not only for the Dodgers but for the baseball world," Ohtani said.
LA baseball fans celebrate Ohtani's decision
Baseball fans in Los Angeles are cheering Ohtani's transfer to the Dodgers.
Some are celebrating the deal over meals in Little Tokyo, one of the largest Japanese-American centers in North America.
"It feels like a dream. With the help of his teammates, Ohtani will take us to the World Series at least two or three times," he said.
Another fan said that he wants to see Ohtani in action as soon as possible.
"[The news is] outstanding. He is a phenomenal player. I cannot wait to have him on the team," he said. "I hope he plays with a lot of fire and a lot of energy, and I hope he can translate that into the team."
Dodgers to kick off 2024 season in Seoul

MLB has been holding official games outside the United States in recent years to boost the sport's popularity.
The 2024 season opening will mark the first time for MLB to play regular-season games in South Korea.
The Padres are expected to field Ohtani's WBC teammate pitcher Darvish Yu and Gold Glove Award-winning player Kim Ha Seong.
