1915-06-11 Jack Dillon nd-w pts 10 Frank Mantell, Harlem AC, Baseball Park, Cincinnati, Ohio, USA - USA. Referee: Lou Bauman. Risking his crown against his old rival once again, Dillon (169) won in a canter, being the master of the situation at all stages of the contest. The only time Dillon, who fought in a cool and deliberate manner, raised his game was when Mantell (168½) caught him with right swings to the jaw that stung him into action. There were no knockdowns despite Dillon’s superiority.
Another fight, with both men inside 158lbs, where both of Dillon’s title claims were risk came against George Chip (drew 10 on 5 July at Association Park, Kansas City, Missouri) and although Dillon weighed 170lbs for a contest against Johnny Howard (nd-w pts 10 on 12 July at Brown’s Gym, Rockaway, Queens, NYC, New York), with the latter weighing in at 160lbs both of Dillon’s title claims were again on the line. A few days later, on 16 July, Dillon took on the Zulu Kid (nd-w pts 10 at Brown’s Gym) in a contest that was also thought to involve his title claim at 175lbs. But as yet the weights are unconfirmed.
