William O'Reilly aka Tiger O'Reilly was one of the greatest cricketers in the history of the game. When retired from playing, Bill became a respected cricket writer and broadcaster. Rated as one of the greatest bowlers, he was quite a tall man (6 ft 2 inches), so he could whirl his arms to an unusual extend.

In 1935, Wisden wrote of him: "O'Reilly was one of the best examples in modern cricket of what could be described as a 'hostile' bowler."
