Ike Blessit tells a story about Billy Martin sending him to the minors or having him released, to the point where it was significant salary wise, not sure the specifics.
But his point was this. Billy had a girl, 16 years old probably, definitely a high school girl, in his room at the Leland hotel in Detroit. He wanted Ike to driver her home. It was like 2 am. She lived in West Bloomfield or something like that. Ike's said no way was he, as a black man, driving a 16 year old white girl around Oakland county after 2 am to drop her off at her house. Billy got mad and blackballed him.
Maybe Ike's lying or mixing up details, he was in part of a hard luck story about him and his hard times. But it's believable. Like Hollywood producers and power brokers and actresses and the casting couch, Weinstein, etc. Maybe not every story is true but there's a lot of them that are.
