Not sure what you mean by having the mets as a rivalry, but the dbacks and giants have been batteling for 1st for the last 5 years, and there have been a few fights such as the one where Charlie Hayes charged Stottlemeyer(sp?) from secondnbase, remember when Randy Johnson put on the Ginats hat? I think either the dbacks or braves could be considered some what of a rivalry.
