Scroll down to Aug. 20, 2005 and click on the video that says "Author Jonathan Niednagel discusses baseball players brain types".

Players mentioned are:

FEAR (ESFP)- Bonds and Pujols
BEIR (ISTP)- Ted Williams, Hank Aaron, Cal Ripken Jr.
BCAR (INFP)- Derek Jeter
FEIR (ESTP)- Pedro Martinez

This is good to look at as you can see the diffrences between the types.
