1933-05-21 Tony Canzoneri w pts 10 Battling Shaw, Henemann Park, New Orleans, Louisiana, USA - LOUISIANA. Referee: Jimmy Moran. Making his first defence, Shaw (136½), despite showing his gameness, was no match for Canzoneri (133), who scored knockdowns in the seventh and eighth rounds to walk off with the unanimous decision. Although Shaw gave Canzoneri a stubborn battle for the first five rounds, after that it was an uphill struggle and he did well to survive.
On 23 June, Barney Ross (134¾) outscored Canzoneri (133½) over ten rounds at The Stadium, Chicago, Illinois to win the lightweight title and following the precedent set by Canzoneri v Jack Kid Berg, the Illinois State Athletic Commission voted to accept that Ross had won the junior welter championship at the same time.
