I would appreciate help identifying some of the signatures and opinions on authenticity, especially of the Derek Jeter and Mariano Rivera signatures.
"Jeter Panel" top to bottom: Mike Stanley (not really visible in this picture), Tony Cloninger (? picthing coach), Jimmy Key, Derek Jeter, Ruben Sierra, Paul O'Neill
"Pettitte panel": Melido Perez, Andy Fox (?), Andy Pettitte, David Pavles, ?, David cone, ?
Buck Showalter sweet spot
"Mariano Rivera" panel: ?, Scott Kamieniecki, Bob Wickman, Mariano Rivera, Jorge Posada, Randy Velarde (?), ?
"Jim Leyritz" panel: Willie Randolph, Russ Davis, Jim Leyritz, Sterling Hitchcock, Tony Fernandez (?), Tony Pena, Bob MacDonald
Also, do I have Ruben
Sierra right? Or is that Ruben
Rivera?
Thanks for any help!
