Sharrock played most of his career as a half forward flanker and was a premiership player in 1963, his first season at Geelong. On 6 July 1963 he was a member of the Geelong team that were comprehensively and unexpectedly beaten
by Fitzroy, 9.13 (67) to 3.13 (31) in the
1963 Miracle Match. Due to an injury to
Roy West, he spent the first half of 1966 playing at fullback before moving to centre-half forward for the second half of the season. He had his best season, finishing third in the Brownlow Medal count. In 1968 he suffered a career ending knee injury during an Inter-League game and despite having represented Victoria at interstate football earlier in the season it would be his last year in the game. ==Life membership==
