Start off with what you have written: Identify his message and mission. From what you write it sounds like his speaking presence is the way to go with this; maybe filming live presentations and selling them off as web/video. Or you could help him ghostwrite a book, and publish it yourselves on Amazon. Or he could become known in a youth program or some other type of charity, summercamps about baseball or something similar.

With regards to message and mission, you could go in different directions with this, although they should most likely circle around one of these themes:
- How he has transformed the MLB-experience into life lessons
- How MLB has helped him become a different person (“Ugly duckling”-theme):
- War stories from the dugout/lockerroom.

A few ideas could be:
- Life story: How did he become and MLB-player? So few become that at any level – what took him all the way? Physical gifts? Persistence? Grit from his childhood? Everybody loves a life story like that.
- What has the MLB-experience taught him about life? Which tools from his career has helped him after retiring?
- How do you maximize the chances to succeed in the big leagues? A How to-story for minor leaguers and college players to follow.
- How to learn to hit a baseball? Document how his mind works. For the interested, that would be fascinating if told correctly.

I think if you start off with 3-4 themes like these, he could become a motivational speaker.

You could also limit this to pure MLB-war-stories, which would probably lower the volume of followers, but it would be a dedicated group. Then the themes could be more specialized also, f.ex.:
- How I won the Silverslugger.
- How I became a great hitter.
- The numbers revolution in baseball – a view from the hitters box. (His view of statistics and its impact on modern baseball).

Good luck with your positioning. These are just ideas I came up with while writing this response. If you want more or want to discuss these further, feel free to set up a call.
