He won the National Boxing Association World Middleweight Title vacated by Mickey Walker with a technical knockout over Oddone Piazza on January 25, 1932, in Milwaukee, Wisconsin. The match was the final round of the championship tournament to decide the new world middleweight champion. With hard rights to the head and body in the third, Jones finished the series with two hard blows to the body and one to the head indicating he was close to ending the bout. In the sixth, Jones pounded Piazza with everything he had, when a solid right put Piazza on the canvas for a count of four. When he arose, he tried to cover up when Jones continued to pound at him, but the referee wisely stopped the bout. On March 31, 1932, Jones defeated powerful hitter Chuck Burns in a third-round knockout in
Akron, Ohio. Jones floored Burns three times in the third with a flock of lefts and rights, before sending him to the mat for the fourth and final time. Burns had not been knocked out in a previous bout. The first two rounds were slow as Jones assessed his opponent, but he came out roaring in the third. In a world middleweight title defense, Jones defeated Young Terry on April 26, 1932, in a twelve-round unanimous points decision before a partisan crowd of 7,000 rooting for Terry, at the Armory in
Trenton, New Jersey. A right to the heart and a short left to the chin made Terry's knees nearly crumble in the eighth, but he avoided a knockout. Terry made Jones miss on occasion, but Jones dominated throughout the bout, took the offensive, and showed better ringcraft in the well fought bout.
Losing the world middleweight championship, June 1932 Jones lost the belt later that year on June 11 in Paris, to Frenchman
Marcel Thil from an eleventh round disqualification. The
New York Times wrote that Jones was losing on points when he was disqualified after having been warned for holding and hitting low. The crowd of 70,000 was the largest to attend a prize fight in Paris for years. == Taking the American middleweight championship, January 1933 ==
