Which Baseball Players Had the Biggest Financial Impact Outside of the Game?

I was wondering which players had the most economic impact outside of the game of baseball?  Why did I think about that?  I looked at a list of players born on this day and a player on the list had a great impact outside of baseball.

Here are the hints to his identity, besides today being his birthday/

1.  He went to high school and college in the same city
2.  He played for six teams over 26 seasons.
3.  He was traded for a player to be named later.
4.  He missed a season with an injury to be named later.
5.  As a pitcher he gave up more than 300 homers.
6.  He throws left-handed, assuming that he still throws sometimes now that he's 73 today.
7.  He had Kellogg's cards in three different seasons.
8.  His Kellogg's cards showed him on the White Sox, Dodgers and Yankees.
9.  He won 20 games in a season three times.
10.  His last name is more common as a first name.

Did you figure it out?

The surgery named after him has become some doctors full-time work.  There are now pitchers who've had the surgery more than once.
