Royle played cricket for Lancashire from 1873 and for Oxford University in 1875 and 1876, winning a Blue both years. His record at Oxford was modest, and he passed 50 only once, making an unbeaten 67 in the match against Middlesex at Prince's Cricket Ground, Chelsea in 1876, when he batted at No 9 and where his runs were part of an Oxford total of 612, the highest score ever made at Prince's. After Oxford, he returned to fairly regular cricket for Lancashire for two seasons and in 1878 he hit his highest score, an innings of 81 against Kent at Town Malling. Despite this fairly modest record as a batsman, Royle was a member of Lord Harris's cricket team to tour Australia in 1878–79, which played one match against Australia. This game has since been recognised as a Test match, the third such game ever played; Royle scored 3 and 18 as the Australians won by 10 wickets, and he also took two catches. In fact, it was Royle's fielding that won particular attention on this tour, and was remembered in glowing terms 50 years later: "He was ambidextrous, very quick on his feet and smart in return," said the obituary in Wisden Cricketers' Almanack in 1930. He is generally regarded as being the greatest "cover point" of all time, and many books have described the fear he engendered in batsmen when on the pitch. Only a rash batsman dared to try for a quick run. A remark of Tom Emmett’s, the famous Yorkshire cricketer, is recalled in Royle's obituary in The Times: "Woa, mate, there's a policeman," he said when his partner called him for a short run while Royle was at cover point. In 1919, when The Times was wanting to make a comparison with Jack Hobbs' prowess as a cover-point field, it cited Gilbert Jessop and Syd Gregory, two long-standing and famous cricketers, plus the relatively unknown Vernon Royle, as Hobbs' only equals.
After cricket
However, after the tour he retired from cricket and took up full-time teaching at Elstree School, though he returned to Lancashire and to various amateur teams for occasional matches through to 1886 and as late as 1891 played for Lancashire in a game against Marylebone Cricket Club at Lord's. He later served as president of the Lancashire County Cricket Club. He was ordained in 1892 when he was a schoolmaster at Elstree; he subsequently became headmaster fleetingly at Elstree before moving to Stanmore Park school, where he was headmaster from 1901 until his death.
Publications
Royle kept a diary of his tour, which was published in 2001 as Lord Harris's Team in Australia 1878–79: The Diary of Vernon Royle. In it he outlines the lavish welcome afforded the touring party. Royle also briefly mentions his views on the Sydney Riot of 1879.
