Since moving up to Light middleweight to successfully challenge
Miguel Cotto in May 2012,
Floyd Mayweather Jr. had spent two months in jail for
domestic abuse. Since his release in August, he spend the rest of the year inactive. In the meantime
Robert Guerrero had defeated
Selçuk Aydın to become the WBC's "interim" welterweight champion in July 2012, and in November he defended it by winning a unanimous decision over
Andre Berto. In the aftermath he called out Mayweather saying, "Pretty Boy, let's do it." In February it was announced that Mayweather would make the first defence of his welterweight title against Guerrero in May, 19 months after he won the title from
Victor Ortiz. The bout was held on May 4, at the
MGM Grand Garden Arena at the
MGM Grand Hotel & Casino in
Las Vegas,

HBO PPV. The card featured some of the rising stars of Mayweather Promotions: J'Leon Love, Badou Jack, Luis Arias,
Ronald Gavril and Lanell Bellows. At Mayweather's insistent a rematch clause was included in the contract. ==The fight==
