In his early career he was based in Yorkshire and won the classic St Leger Stakes at Doncaster Racecourse as a three-year-old in 1802.

[1] Orville's dam Evelina, also bred by Fitzwilliam, was a half-sister of the St Leger winner Pewett, and went on to produce the successful stallions Cervantes and Paulowitz.

[4] On 23 September Lord Fitzwilliam's colt recorded his first success when he won a race over one mile at Doncaster Racecourse in which he started the 4/5 favourite against four opponents.

He returned to York in August when he finished last of the five runners behind Haphazard in a four-mile subscription race and second to R Garfoth's horse by Traveller in a similar event two days later.

[10] In September at Doncaster Orville won the two mile Free Handicap Sweepstakes and a four-mile match race against Mr Mellish's horse Stockton.

Following a dispute with the Jockey Club in 1791, the Prince's horses did not run at Newmarket: when Orville appeared at the course he was temporarily transferred to the ownership of Delme Radcliffe.

[14] On 31 October, Orville again failed to show his best form at Newmarket, where he finished unplaced in a handicap race over the two mile "Ditch-In" course.

[16] Orville began his final season at Newmarket in March where he finished fourth in the Oatlands Stakes, a handicap race in which he carried top weight of 132 pounds.

At the next meeting in April he won a Free Handicap Sweepstakes over the Beacon Course, conceding eight pounds to the Oaks winner Pelisse.

He won a match against Pelisse, a Sweepstakes, beating Cerberus and the Ladies' Plate in which he conceded forty-one pounds to a three-year-old colt named Brighton.

[18] Orville ended his career at Newmarket in autumn with two further wins beating Canopus in a subscription race over the Beacon Course on 28 September and Parasol in a similar event on 9 October.
