The Dodgers introduced Trevor Bauer at his press conference last week. At that press conference, it looked as though Bauer would be wearing number 27 this year since that was what his jersey indicated at the event.
Now there is reason to believe that Bauer will be going back to 47. On the Dodgers official page, his number is listed as such. Bauer worse number 47 while he played in Cleveland from 2013 into 2019. He made the switch to 27 when he was traded to the Reds, a number he wore originally with the Diamondbacks.
