Help with multi-signed baseball

[speers]

A couple of years ago, while visiting San Francisco, I was talking with some people from the charitable arm of the Giants and they offered a couple of multi signed balls. I gave up trying to figure out the autos until today when someone was able to decipher a few. Now I want to solve the puzzle and I need some help. I'll post one for now (as I have to find ball #2).

So far I "think" I've been able to decipher the following:

Charlie Silvera (1948-57) 6x world series champ with the yankees
Tom Hafey (1939-44)

Russ Rose (1946-57 minors)
Roger Osenbaugh (1952-59 PCL)

The ball is a National League William White era baseball (1989-94)

Can't find a connection between the players (potentially) identified to help narrow the search for the rest. If anyone has any ideas on a connection or can identify the other autos I'd love to hear your thoughts! Links to autograph samples, players bios, etc related to guesses are always appreciated.

Appreciate the help in solving the puzzle!

Andrew
