John “The Quietman" Ruiz (born January 4, 1972 in Methuen, Massachusetts), is a former American professional boxer of Puerto Rican descent, Ruiz is the first Latino Heavyweight Champion and former two-time WBA World Heavyweight champion. After a professional career spanning over 18 years, the two-time WBA world champion officially announced his retirement from the sport at a press conference on April 26, 2010. His final fight was a title shot against current WBA Heavyweight Champion of the World David Haye, in which he was defeated by TKO in round 9.
Ruiz has defeated three world champions, Evander Holyfield, Hasim Rahman and Tony Tucker, as well as top contenders such as Andrew Golota, Fres Oquendo, Jameel McCline and Kirk Johnson.
He is currently residing in Las Vegas, Nevada.
His professional record is 44–9–1–1, with 30 knockouts. Frustrated by years of criticism from the boxing press and fans, he retired upon his second loss of the WBA Title on April 30, 2005 (to James “Lights-Out” Toney). Ruiz un-retired in 10 days, after finding out that James Toney had tested positive for anabolic steroids. The official outcome, a unanimous-decision defeat, was changed to a no-contest; the WBA ordered that Ruiz retain the title. Ruiz then filed a lawsuit against Toney, claiming that he had damaged Ruiz's boxing career (due to Toney's use of illegal steroids before their bout).
On December 17, 2005 he lost his title for the third time — in controversial fashion, — to Nikolay Valuev. Ruiz lost a rematch for the vacant WBA Heavyweight title with Valuev on August 30, 2008.
