Help with a couple of Dodgers signatures

[Rays & Mariners]

Hi All,

Could use some help with a couple of Dodgers autographs. The ball was signed at an Old timers game in 89.

In the first pic I need help with the 2nd signature and the 2nd pic I need help with the signature above Koufax.

Thanks!
Eric
