What charities, MM? I’ve known about Holliday, Jay, Wainwright, and Goldy (who wasn’t on your list), but not the rest.
Add Goldy and Pujols.
Almost all of these guys at one time or another had charity events such as golf tournaments or cornhole contests or Waino’s game (is it NFL or NHL). A while back I read an article regarding professional players income and it stipulated that most of the investment counselors advised forming a foundation or charity that would help improve their reputation and maybe even the bottom line(?). Nobody is forced to do it but it has become an expected thing of most professionals. The degree to which they participate is pretty much equal to their success as a professional player. Even Carlos Martinez is very active with a charity and a lot of good publicity from it. Voit I am not sure of but when he gets that big contract I am sure there will be something founded with his name on it. Matt Adams I will admit has to find a permanent home to get active in the charity business.
