The right-arm spinner from Australia had a short but exquisite Test cricket career. He was considered extremely tough to play even on batsmen-favoring pitches, let alone on pitches that favored bowlers. His medium-pace style of spin bowling was well-respected in the cricket community.

He reached the number 1 spot in Test cricket in March 1882 by taking 11 wickets in Sydney Cricket Ground followed by 9 wickets in the next match. His reign lasted 12 matches and 933 days between 1882 and 1886 after which his Test career was cut short owing to a kneecap injury. He continued to sporadically play domestic cricket for nearly a decade.
