Jesús Castillo Aguilera (June 17, 1944 – January 15, 2013) was a Mexicanprofessional boxer. Better known asChucho Castillo, he was theUndisputed,WBA andWBCbantamweight world champion in 1970.^[1]

Castillo andRubén Olivares sustained one of the most important rivalries in the history of Mexican boxing. Castillo was described by the boxing bookThe Ring: Boxing In The 20th Century as quiet and sullen, while Olivares was more of an outgoing partygoer, according to the book. The personality contrast made fans very interested in their matches.^[2]

Castillo was born in Nuevo Valle de Moreno, a small town in the municipality ofLeón, Guanajuato,Mexico. He made his professional debut on 26 April 1962 against Carlos Navarrete, suffering his first loss by a decision after six rounds. His next bout was his first win, outpointing Arnulfo Daza in eight rounds.^[3] Castillo built a record of 24 wins and 7 losses, with 11knockout wins, before facingJosé Medel for the Mexican Bantamweight title on 29 April 1967. He won the title on points after the twelve rounds, retaining it twice and also winning an additional seven non-title bouts before his first world title challenge.^[4] Among the fighters he beat during that streak wereJesus Pimentel and Memo Tellez, who had beaten Castillo twice before.^[5]

Castillo made his first world title attempt against Australia'sLionel Rose, the firstAboriginal Australian ever to win a world title. The fight was held on 6 December 1968 at theForum inInglewood, where Rose won a very unpopular fifteen-round decision in front of a decidedly pro-Castillo crowd, causing ariot.^[6] Castillo had eight bouts in 1969, going 5-1-2 during that period. He beat future world championRafael Herrera to defend his Mexican title, had a ten-round draw in Tokyo with Ushiwakamaru Harada, drew with Medel, and split two decisions with Raul Cruz.^[7]

In 1970, Castillo was given a second world title chance when he and Olivares clashed to begin their three fight rivalry, with all three fights taking place at the Forum in Inglewood.^[8] On 18 April, Olivares retained the crown by outpointing over Castillo. However, a rematch between the two fighters took place on 16 October. Castillo cut Olivares in round one, and when it was determined that Olivares could not continue in Round 14, Castillo was declared winner by a technical knockout, winning the world bantamweight championship.^[9][10] After one non-title win, Castillo met Olivares for a third time on 3 April 1971, when Olivares recovered the crown by outpointing Castillo despite suffering an early knockdown.^[11]

Castillo went on fighting until 1975, but his record from the third Olivares fight until his retirement was a rather ordinary one of 5 wins and 7 losses. He lost to former or future world championsEnrique Pinder,Bobby Chacon, andDanny "Little Red" Lopez. After losing to Ernesto Herrera on 12 December 1975, he retired.^[12][13]
