Jimmy just likes to run his mouth, but also, there's no need to actually have one of those "retire as a Phillies player" ceremonies. He'll get plenty of ceremonies.
If he really seriously wanted to do that it would have had to have been last season, when the team was losing, and even then it probably doesn't happen.
It doesn't even make sense, really - he's saying he wants it be more than "ceremonial," but the whole process just calls further attention to the fact that it is. It would be a stunt, not something he earned.
"If we do it for Jimmy we might have to do it for Chase" is definitely not something I'm worried about though
