Assistance, please on identifying signature - 1977 SF Giants ball

[jdunevant]

I'd appreciate any assistance identifying a signature on a 1977 SF Giants ball. It's on the sweet spot directly below Joe Altobelli's and appears to be "Joe Lisker' (or maybe Lister?) or some other derivation on the last name. Anyone know and what his tie to the Giants was? Thanks, Jim.

Trainer Joe Liscio?

Thanks, I think that's it! Appears he was the trainer from around '75 to '82 to matches up with the year.

Thank you!
