Nate Diaz submits Jim Miller in the second round of their main event fight at UFC on Fox 3: "Diaz vs. Miller" last night (Sat., May 5, 2012) from the IZOD Center in East Rutherford, New Jersey. In becoming the first man to finish Miller throughout his long and illustrious professional career, Diaz likely earned a shot at Anthony Pettis in a true number one contender bout. It was said he might earn a title shot with a victory over Miller but the reality is the 155-pound division is still in limbo with the Ben Henderson vs. Frankie Edgar rematch still not scheduled and Pettis as high on the totem pole. So why not hold a mini tournament of sorts and let it sort itself out that way? Either way, Diaz was incredibly impressive in victory tonight, looking as good as he ever has against a dangerous opponent.
