An unusual feature of Nyren's career is that, in an age when "given men" were the norm rather than the exception in cricket teams, he was never recorded as playing for anyone other than Hambledon/Hampshire. The same applied to his bowling partner Thomas Brett. Scorecards began to be kept habitually from the 1772 season and Nyren was recorded in 48 first-class matches, plus some single wicket matches, from then until he retired in 1784. The strength of the Hambledon/Hampshire team during Nyren's captaincy can be seen in its being rated the (unofficial) Champion County in 10 seasons: 1766–1771 inclusive, 1776–1777 inclusive, 1779 and 1783.
