Raynor was educated at Brentwood Grammar School, from where he won a scholarship to Winchester College, and at St John's College, Cambridge. At Winchester, he was a right-handed middle-order batsman and a right-arm fast bowler, but at Cambridge he batted very low in the batting order. The 37 not out that he made in the match against Surrey in 1872 constituted more than half of his total first-class runs and was made from No 11 in the batting line-up. In the previous match, he had taken five wickets in the second innings of the Gentlemen of England game for 44 runs, and this was the best bowling performance of his first-class career. He was picked for the 1872 University Match against Oxford University, but was not successful, failing to take a wicket. In 1873, he played only a single match, again with little success, and was not selected again.
