Gatti had incredible heart, and an iron chin, shown in the majority of his major fights. He was able to absorb incredible amounts of punishment by fighters such as Wilson Rodriguez, Gabriel Ruelas, Angel Manfredy, Ivan Robinson, Oscar De La Hoya, Micky Ward, Floyd Mayweather and Carlos Baldomir, none of whom could knock him out cold. In the Rodriguez fight he showed off his recuperative abilities as he was close to being stopped under a barrage of shots and in the next round he stopped his opponent.
