Ambidexter was a bay horse sired by the 1783 St Leger winner Phoenomenon who stood as a stallion in Yorkshire for several years before being exported to the United States where he died in 1798.
[2] Hill and Goodricke were part of a group of Yorkshire based owners and breeders which also included Gilbert Crompton and Mr Dealtry.
In August, Ambidexter returned to York where he finished second to Henry Pierse's grey filly Contessina in a two-mile sweepstakes.
[5] On 28 September, Ambidexter was one of eight three-year-olds, from an original entry of fifteen, to contest the St Leger Stakes over two miles at Doncaster Racecourse.
Ridden by his trainer George Searle, Ambidexter won the classic from Lord Archibald Hamilton's unnamed bay colt, with Spanker in third.
