Johannesburg will attempt to atone for his Kentucky Derby debacle in Saturday's Group 1 Golden Jubilee Stakes at Royal Ascot against a field of older horses that includes the American sprint star Caller One.

The Golden Jubilee, run over a straightaway six furlongs on turf, is the feature race on the fifth and final day of the Royal Ascot meeting.

Johannesburg, unraced since finishing eighth in the Kentucky Derby, faces 15 others. Trained by Aidan O'Brien, Johannesburg is seeking his first win since the Breeders' Cup Juvenile at Belmont Park last October.

ASCOT, England - Grandera won the Prince of Wales's Stakes at Royal Ascot Wednesday by five authoritative lengths, as Breeders' Cup Filly and Mare Turf winner Banks Hill finished third against males.

Held back in the early going, Grandera, under Frankie Dettori, showed an excellent turn of foot to lead approaching the final furlong, and soon put the result beyond doubt.

ASCOT, England - Rock of Gibraltar, the European miling sensation, won his fifth straight Group 1 race with a 1 3/4-length score Tuesday in the St James's Palace Stakes on opening day at Royal Ascot.

Rock of Gibraltar is the first horse to win five straight Group 1's in Europe since 2000 Breeders' Cup Classic runner-up Giant's Causeway. A sixth would match the record set by Mill Reef.

Showing good speed at the furlong pole, Rock of Gibraltar outfinished Landseer. The winner went off as a 4-5 favorite. Both horses are trained by Aidan O'Brien.

LONDON - Uncertainty is the order of the day for the Group 1 Prince of Wales Stakes, the feature race on Wednesday, the second day of Royal Ascot in England.

Breeders' Cup Filly and Mare Turf winner Banks Hill and Dubai Sheema Classic winner Nayef are favored over 12 others in the 1 1/4-mile race, but both have concerns with the surface.

The going at Ascot is currently good to soft, and connections of both the favorites have expressed a preference for faster ground. Both would benefit from improvement in the course, but have performed well on softer surfaces in the past.

Royal Ascot, Great Britain's most prestigious racing meet, begins Tuesday, lengthened this year to a fifth day to celebrate the Golden Jubilee of Queen Elizabeth II. The opening-day card has four group stakes, topped by the Group 1 Saint James's Palace Stakes.

Rock of Gibraltar, winner of the English and Irish 2000 Guineas, is likely to be a prohibitive favorite in the Saint James's. Trained by Aidan O'Brien, Rock of Gibraltar is primed for his fifth consecutive Group 1 victory.

British, German, and French raiders are among the seven runners for the Group 1 Gran Premio di Milano, over 1 1/2 miles at San Siro in Milan, Italy, on Sunday. But for once, the Italians have a horse good enough to handle the challenge: Falbrav.

A son of Fairy King, Falbrav has won four of his five races since finishing second to Morshdi in last year's Italian Derby. He showed that he is still improving when he beat the Godolphin-owned Ekraar in the Group 1 Premio Presidente della Repubblica, over 1 1/4 miles at the Capannelle in Rome on May 12.

NEW YORK - A funny thing happened on the way to the finish lines of the three 1 1/2-mile classics run in England and America this past weekend.

In all three races - the English Oaks, the Epsom Derby, and the Belmont Stakes - two horses outstripped all of their other rivals by wide margins. You needed the patience of Job to wait for the arrivals of the third-place finisher in each case.

The 2003 Dubai World Cup will be run on Saturday, March 29, as the climax of the newly established seven-week Dubai Racing Carnival at Nad Al Sheba.

The new program includes the establishment of the Dubai Triple Crown consisting of the one-mile Group 3 UAE 2000 Guineas on Feb. 13, the 1 1/8-mile Al Bastikiya, moved from three weeks after the UAE Derby to three weeks before on March 8, and the $2 million 1 1/4-mile Group 2 UAE Derby itself on March 29.

Aidan O'Brien, the Irish training maestro, continued his domination of the British colt classics with a one-two finish in the Vodafone Derby at Epsom on Saturday.

High Chapparal and Hawk Wing, two of the three O'Brien runners, had the race between them through the final quarter-mile, with High Chapparal coming home two lengths clear of his stablemate. There was a 12-length gap back to the front-running Moon Ballad, who finished third. The winning time for the 1 1/2 miles, on turf rated good to soft, was 2:39.45.

Coshocton was put down after falling near the finish.

The European classic scene moves back to France Sunday to the elegant surroundings of Chantilly for a wide open renewal of the Prix de Diane or, as it is better known in the English-speaking world, the French Oaks.

Fifteen 3-year-old fillies will line up for the $475,000 Group 1 contest which will be run at 1 5/16 miles on the idyllic racecourse graced by not one, but two, 17th Century castles. Just who will crowned the Thoroughbred queen of France is a moot question, however, as seven of the evenly matched contestants are coming off stakes victories.
