Leslie O'Brien "Chuck" Fleetwood-Smith was a cricketer who played for Victoria and Australia. Known universally as "Chuck", he was the "wayward genius" of Australian cricket during the 1930s. A slow bowler who could spin the ball harder and further than his contemporaries, Fleetwood-Smith was regarded as a rare talent, but his cricket suffered from a lack of self-discipline that also characterised his personal life. In addition, his career coincided with those of Bill O'Reilly and Clarrie Grimmett, two spinners named in the ten inaugural members of the Australian Cricket Hall of Fame; as a result he played only ten Test matches but left a lasting impression with one delivery in particular. His dismissal of Wally Hammond in the fourth Test of the 1936–37 Ashes series has been compared to Shane Warne's ball of the century. He has the unwanted record of conceding the most runs by a bowler in a Test match innings.
Holding little regard for the other disciplines of the game, batting and fielding, he attracted a lot of attention with his rare style of bowling: left-arm wrist spin.
