Salvio's game improved in tandem with his rise in society. He had emerged as the strongest contender to Paulo Boi in 1598. The Neapolitan was 28 and full of fight. The champion from Syracuse was now 70 and weary after a long and action packed life.
Salvio challenged Boi. A match was arranged. No record of the games themselves have survived but we know that Salvio dethroned Boi. Boi, in poor health, died three days later.
Some accounts given of the time report less than fulsome praise for Salvio's success. They cite Boi's age and deteriorating health. There may have been a grain of truth in this.
A younger and healthier Boi might have been a much higher mountain to climb. They could not question however that Salvio was now the best. Salvio defeated the strong master Geronimo Cascio in 1606. He would remain champion until 1620.
