Ruddock was also known for his exceptionally heavy punching; some of the best examples of his left hand and overall power was his knockouts of former WBA heavyweight champions James Smith in 1989, Michael Dokes in 1990, and Greg Page in 1992. His favoured weapon at the ring proved to be a highly versatile half-hook, half-uppercut left-handed punch he called "The Smash" which accounted for the majority of his knockout wins -- it also happened to be his major downside throughout his career. Being a left-handed puncher fighting out of the orthodox stance, he didn't throw a single right hand during most knockout flurries.
