1906-01-19 (142lbs) Joe Gans w co 15 (25) Mike Twin Sullivan, Woodward’s Pavilion, San Francisco, California, USA. Referee: Jack Welch. According to the Philadelphia Item and San Francisco Chronicle the fight was for a version of the title with Articles of Agreement calling for the men to come into the ring at 142lbs. It ended after Gans landed heavily to head and body before smashing home a left to the jaw that dropped Sullivan for the full count. Gans was on top for most of the contest, standing right up to Sullivan and continually hurting him with rights to the body, while using the left to open up the latter’s guard.
On 17 March, Gans again met Sullivan, this time at Chutes Park, Los Angeles, California, knocking him out in the tenth of a scheduled 25-round contest. Although billed as a 142lbs title fight, Sullivan came in six pounds over the limit.
Defending his 142lbs title claim in a short distance fight, Gans (137) met Willie Lewis (nd-w pts 6 at the Twentieth Century AC, MSG Concert Hall, Manhattan, NYC, New York on 18 May). Lewis, who was well beaten according to the press, came in at 142lbs.
Two other short-distance bouts for Gans that were thought to have been made at 142lbs, both held at the National AC, Philadelphia, Pennsylvania, came against Harry Lewis (nd-w pts 6 on 15 June) and Jack Blackburn (nd-w pts 6 on 29 June).
Later in the year, on 23 October, it was reported that Gans had decided against continuing as a welter as he could comfortably make 133lbs. He was also happy to forfeit his title claim to Joe Thomas, whom he considered to be the best man at that time.
