More heinous allegations against former MLB star Milton Bradley ... his wife, Rachel Bradley, is now accusing the ex-baseball player of threatening to kill her in front of their 5-year-old son.
Rachel made the claim in new court docs, obtained by TMZ Sports, in which she's asking a judge for a temporary restraining order from the 43-year-old.
In the documents, Rachel -- who got married to Milton in 2015 -- says the former Los Angeles Dodger told her on Feb. 6, 2022, that he was going to kill her while her mother and their son were in the room.
