yeah id say Willie, thats who i guessed it was before i read that it was your guess too.
also recognize jerry mumphrey since he was a cardinal for some time.
found this Rick Sutcliffe photo, haven't seen a portrait style photo of him with the Cardinals before this photo.

I think it might be Eduardo Perez who was also in Spring Training 1999
Here is a Comparison, also from Getty
