Deletion of World Series runner-ups

Comment: This strikes me as a  violation.  And not particularly interesting research at that.  Author is apparently trying to tie together losing a World Series to not winning another - but only since 1991.  This is demonstrated quite clearly in the master list at World Series and really only needs a line in the trivia section of that article
