HUH! Ooh, Look something shiny

The other day my son and I went to the local Goodwill, while killing some time.  As usual I looked in the ball bin and found four balls that I bought.  First I found a shiny Disneyland Star Tours baseball.  Then I found a unsigned South Atlantic League ball, which is kind of unusual, since I live in Portland, Oregon.
 

Then I found a couple of signed balls that I have no idea who they are.  They are both on California League Balls.  Any help would be appreciated.  Oh and I spent 99 cents for each ball.
