Kevin Youkilis -- His family name is Greek, but Youkilis is Jewish. Youkilis holds baseball's all-time record for most consecutive errorless games at first base.
In an oddity, it was noticed in 2007 that various baseball websites had been using "youkike" as part of their urls for Youkilis' statistical webpages. Kike is a slur for a Jewish person. This formatting occurred on sites that employ an automatic url-creating program which combine the first five letters of a player's surname with the first two letters of his first name.
On August 8. 2005, while playing for the Red Sox, Youkilis took the field in the 9th inning along with Adam Stern and Gabe Kapler setting a record for the most Jewish players on the field at one time in AL history, and the most in MLB history since four Jewish players took the field for the NY Giants in a game in 1941.
