The Red Sox traded Eaton to the Athletics on Thursday in exchange for minor-league pitcher Jareth Rayo, Bob Nightengale of USA Today reports.
Eaton appeared in 24 games for the Red Sox this season, going 8-for-50 (.160) at the plate while tallying six RBI, four runs scored and two steals. He had a bit more success in the minors to the tune of a .254/.338/.412 slash line over 363 plate appearances, and he'll likely compete for a spot on the Athletics' Opening Day roster in 2027.
