 From the early 1930s through the end of his career in 1950, Savoldi was credited as having originated the move but today that attribution is disputed between him and Abe Coleman.Interpromotional wars were raging at the time, and on April 7, 1933 at Chicago Stadium, Savoldi was involved in a double cross on heavyweight champion Jim Londos.After a tangle by the ropes, referee Bob Managoff declared Savoldi the winner by pinfall and awarded him the title.
