Born
Hiroji Satoh won the 1952 world singles title in Bombay as an unknown, using a bat covered in thick sponge that made the ball silent and unpredictable. Opponents used to hard rubber could not read it. His win started the sponge era and led the ITTF to set limits on rubber thickness, one of the most important equipment changes in the sport.
