Willie Mays
Good call on Willie!!
There's two
#3 Yogi Berra also retired a Met after starting with the Yankees
Good one with Berra, didn't have him on the list, probably because he was a player/coach with the Mets. So that brings the total up to 7, with at least 3 still not named. (See I say least because I knew there would be guys I didn't have on the list like Berra).
TP's for all the right answers so far, and SShorefan 3.0 I would give you more for Berra since he wasn't on my list if I could...
and Darryl makes 5...
