Miguel Ángel Cotto Vázquez (born October 29, 1980) is a Puerto Rican former professional boxer who competed from 2001 to 2017. He is a multiple-time world champion, and the first boxer from Puerto Rico to win world titles in four weight classes. In 2007 and 2009, he reached a peak active pound for pound ranking of seventh by The Ring magazine. Cotto started out his career as a hard-hitting pressure fighter, but evolved over the years into a more refined boxer-puncher as he moved up in weight.
As an amateur, Cotto represented Puerto Rico in the lightweight and light welterweight divisions at various international events, including the 1999 Pan American Games, the 2000 Olympics, and the 1998 Junior World Championships; the latter in which he won a lightweight silver medal. Having begun his professional career in 2001, Cotto defeated Kelson Pinto for the WBO light welterweight title in 2004. He made six successful defenses before vacating the title to move up in weight. In his first welterweight fight, in 2006, Cotto defeated Carlos Quintana for the vacant WBA title. He successfully defended it four times before a career first loss to Antonio Margarito in 2008. The following year, Cotto won the vacant WBO welterweight title and defended it once before losing it to Manny Pacquiao in the same year.
In 2010 he moved up to light middleweight and won the WBA title from Yuri Foreman. Having been promoted by the WBA to Super champion status, Cotto won a 2011 rematch against Margarito. He lost the WBA (Super) title in 2012 to Floyd Mayweather Jr., in one of the most anticipated fights in modern boxing history. The year would end on a further sour note for Cotto, as he lost in an upset to Austin Trout. Two years later, Cotto defeated Sergio Martínez to win the unified WBC, Ring, and lineal middleweight titles. In doing so, he became the first four-weight world champion from Puerto Rico. In 2015, he defended his titles once before losing to Canelo Álvarez. After more than a year of inactivity, Cotto returned in 2017 to become the WBO light middleweight champion, but lost the title in his final fight to Sadam Ali. Wikipedia
