The Pilots were full of guys just like this.
This is not, repeat NOT, the Hall of Famer that had a brilliant career with the Cubs.
This Billy was a career minor leaguer when he finally got his shot in the show. On August 15, 1969, the 36 year old Williams was called up the Pilots.
His career (total career here, not just with Seattle) was 4 games, in which he went 0 for 10 with a walk and a run scored.
It must be pretty depressing when you're too crappy to stick with the 69 Pilots.
