as nelson's professional, constantine was immediately successful. although he produced better figures in subsequent years, he considered his first season at nelson the most enjoyable of his life, owing to the freedom and excitement of the cricket. in nine years at the club he scored 6,363 runs at an average of 37.65 and took 776 wickets at 9.50. his highest score was 192, and his best bowling figures were ten wickets for ten runs. in each season except for 1932, he averaged over 30 with the bat and in 1933 he scored 1,000 runs at an average of over 50. he took over 70 wickets every season and his bowling average never rose above 11.30; in five seasons, he averaged under ten runs per wicket. in 1933 he took 96 wickets, his highest seasonal aggregate, and had he not missed two games to play for the west indies touring team, would likely have completed the cricketer's double (1,000 runs and 100 wickets), an unprecedented feat in the league.
