About Mike Twin Sullivan
Lived 1878 – 1937 (aged 59). Mike Twin Sullivan was an American boxer.
Mike "Twin" Sullivan (September 23, 1878 – October 31, 1937) was an American boxer credited with taking the Welterweight Championship of the World on April 23, 1907, when he soundly defeated William "Honey" Mellody in Los Angeles in a twenty-round bout. He vacated the title in the late fall of 1908, when he could not make weight.
He had an impressive knockout percentage and record and fought some of the greatest boxers of his era including Joe Gans, while he was the reigning lightweight champion, as well as welterweight champion Harry Lewis, and leading welterweight contenders Jimmy Clabby, and Jimmy Gardner whom he defeated.
Early career Mike "Twin" Sullivan was born in Cambridge, Massachusetts, on September 23, 1878, and resided in neighboring Boston for much of his career. He had a twin brother Jack, the origin of his nickname, "twin", and was the youngest in an Irish family of several siblings. His twin Jack was an accomplished middleweight boxer as well, once claiming the Middleweight Championship of the World when he defeated Tommy Burns on March 7, 1905. Jack fought top talent as did Mike, and they shared a few of the same opponents. His brother Dan was a less well known boxer.
Sullivan had three historic bouts with Hall of Famer and reigning lightweight champion Joe Gans, in September 1905 and January and March 1906 with the first in Maryland and the last two in San Francisco and Los Angeles. Significantly, Sullivan lost the last two bouts to the lightweight champion by knockout and technical knockout, though their first bout was a close draw. In the San Francisco fight, Sullivan's first sanctioned Welterweight World Title match according to BoxRec, Gans won by knockout in the fifteenth of twenty rounds. In an important note, the Rock Island Argus wrote of the San Francisco fight, "Gans showed wonderful form and was easily the master of his white antagonist at all times." It did allow that the first three rounds were fairly even fighting. After his fights with Gans, Sullivan met Rube Smith, an accomplished welterweight contender three times in April, July, and August 1906 in Colorado, winning in an eighteenth round knockout in April, but drawing in the other two matches.
Sullivan lost to future welterweight Harry Lewis on February 21, 1907, in a ten-round points decision in Denver. Lewis would use this victory and his subsequent knockout of Honey Mellody one year later on April 20, 1908, to establish what most boxing historians consider a legitimate claim to the World Welterweight Title. Many boxing sanctioning organization today simply fail to list World Welterweight champions prior to 1910 or 1915, as most of these organizations did not exist during that period, and there was less widespread recognition of world champions. The Washington Evening Star noted that "during the early rounds Mellody had an even break with his clever opponent", but "Sullivan came back strong and from the twelfth had it all his own way." "The "Twin" was immediately recognized as a World Champion in the state of California, and has since been recognized widely by American boxing historians including widely recognized authority Nat Fleischer and a host of newspapers. Sullivan relinquished the title around October or November 1908 according to BoxRec as he was above the welterweight limit.
Boxing two leading welterweight contenders He fought Jimmy Gardner, a welterweight contender at least four times. Gardner was another welterweight during the period who attempted to claim the world title as his own. They met on December 18, 1902, and January 27, 1903, with one fifteen round draw, and one five round newspaper win. On November 24, 1905, he beat Gardner on points in 20 rounds in San Francisco. He beat Gardner again in what was deemed a Welterweight Title match on April 22, 1908, in a 25- round points decision at Jeffries Arena in Vernon, California, with the legendary heavyweight ex-champion Jim Jeffries as referee. Sullivan fought Gardner again on November 29, 1909, at the Grand Opera House in New Haven, Connecticut, in a 12-round draw by newspaper decision of the Boston Globe.
World Middleweight Title bout with Stanley Ketchel
Fighting as a light middleweight at 150 pounds, he lost a Middleweight Title Bout against reigning Middleweight Champion Stanley Ketchel by first round knockout, on February 22, 1908, at Mission Street Arena in Colma, California. It was rare for Sullivan to lose by knockout, and made the bout more memorable for supporters of Ketchel. Some boxing critics believe that Sullivan's career began a slow descent after this loss.
