Grand Prix de Paris winner Yawa. The race was run on soft ground which forced the withdrawal of Caerleon and led to doubts about Sun Princess's participation until shortly before the race. The Hern stable entered a pacemaker named Sailor's Dance who led at a moderate gallop before Sun Princess took the lead in the straight. On this occasion she had to be driven out by Carson to win by three-quarters of a length from the French-trained Esprit du Nord, with Carlingford Castle third. It was the second time that Hern had won the Oaks-St Leger double, having been successful with the Queen's filly Dunfermline in 1977. On her final appearance of the season, Sun Princess was sent to Longchamp Racecourse in Paris to contest the Prix de l'Arc de Triomphe. Sailor's Dance once again set the pace before Sun Princess took over before the straight. She held off challenges from Time Charter, Stanerra, and Diamond Shoal but was overtaken fifty metres from the finish by All Along and finished second by a length. 1984: four-year-old season Sun Princess stayed in training as a four-year-old in 1984, but failed to reproduce her three-year-old success. On her seasonal debut she met Time Charter again in the Coronation Cup, but was no match for the older mare and was beaten four lengths. In July she ran in the King George for the second time and finished fifth behind Teenoso. She was off the course until the Arc de Triomphe in October, where she finished unplaced behind Sagace. According to Timeform "the old sparkle had gone". Assessment Sun Princess was awarded a rating of 130 by Timeform in 1983 and 120 a year later. In the 1983 International Classification, an official ranking of the best European horses, Sun Princess was rated the equal fifth-best horse in Europe, behind Shareef Dancer, All Along, Habibti and Caerlon. In their book A Century of Champions, John Randall and Tony Morris rated Sun Princess a "superior" Oaks winner and the thirty-second best filly of the twentieth century to have been trained in the United Kingdom or Ireland. After her death, Carson described her as being a difficult horse, but "possibly the best filly I ever rode", adding that "if she'd learned to relax enough she would have been the best you've ever seen." Breeding record Sun Princess was retired to a breeding career at Ballymacoll. She was
