Are there any players (past or present) where you incorrectly assumed their legal name?

For example:

Greg Maddux is Gregory Maddux

Tom Glavine is Thomas Glavine

But John Smoltz is not Johnathan Smoltz it's just John

Obviously there are guys like Goose Gossage and Buster Posey and Jazz Chisholm where there isnt necessarily the direct correlation to their legal name.

But some of my personal favorites are:

Willie Mays isnt William it's Willie

Until recently I thought Yu was short for something but his name is listed as Farid Yu Darvish Sefat (Darubisshu Sefatto Farīdo Yū)

Xander Bogaerts isnt Alexander it's Xander

Ken Griffey Jr is short for Kenneth but his legal name is George Kenneth Griffey

Ty Cobb isnt Tyler or Tyson it's Tyrus

Kirby Puckett is legally Kirby

And the one that started this thread in my mind is Bobby Abreu. He's just Bob Kelly Abreu
