Who was the 1st modern free agent signed who was not a pitcher?

These questions are pretty tough. I can't even come up with a guess for this one.
How about a hint, what year?

Bloomberg....now the mayor of the Big Apple.

It is with deep regret I will even mention this name but in the interest of fair play.Jackson. Catfish was the 1st actual FA signed by the Yanks.Thought you would get this one.Jimi still in the lead with 2.

You got me on that one Ted. I didn't even think you would post a question that had Jackson for the answer
