Nathaniel captured his first Group 1 race and stamped himself as an elite 3-year-old by beating older horses in the King George VI and Queen Elizabeth Stakes on Saturday at Ascot.

The race, however, was marred by the breakdown of Godolphin’s Rewilding, who had won the Sheema Classic and Prince of Wales’s Stakes in his two starts this year. Rewilding had been held up in last much of the trip and went bad as soon as jockey Frankie Dettori swung out for his stretch run. Dettori walked into a waiting ambulance. Rewilding badly broke a cannon bone and had to be euthanized.

Scalo, winner of a Group 1 in Germany last September, will be favored to win another race at that level in Sunday's Group 1 Grosser Preis Von Berlin at Hoppegarten Racecourse in Germany.

Trained by Andreas Wohler, Scalo was second in the Group 1 Gran Premio di Milano in Italy on June 12. In Sunday's race, worth approximately $221,000, Scalo, a 4-year-old colt by Lando, will be ridden by French jockey Maxime Guyon, who was aboard the colt for a win in the Group 2 Prix Guillaume d'Ornaro at Deauville, France, last year.

There are just five entrants in Saturday’s Group 1 King George VI and Queen Elizabeth Stakes at Ascot in England, but the race is a dandy, with two champions, Workforce and St. Nicholas Abbey, opposed by Rewilding and the dangerous 3-year-old Nathaniel. The fifth horse is Debussy, who won the 2010 Arlington Million but has shown little so far in 2011.

Blue Bunting rallied from fifth in the final quarter-mile to win Sunday’s Group 1 Irish Oaks at the Curragh, her second major trophy of the year.

Blue Bunting won the English 1000 Guineas in May. In between, she finished fourth in the English Oaks, just missing third after jockey Frankie Dettori did not ride her to the wire. He was given a 10-day suspension for the incident.

Dettori made no such mistakes in deep stretch of the Irish Oaks.

Wonder of Wonders, the runner-up in the English Oaks last month, will be an odds-on favorite against a strong field in Sunday’s Group 1 Irish Oaks at the Curragh.

One of three runners in the race trained by Aidan O’Brien, Wonder of Wonders will be after her first group stakes win in the Irish Oaks, which is run over 1 1/2 miles on turf and is worth approximately $600,000.

O’Brien also starts the outsiders Amazing Beauty and Gemstone.

Neither Irish Derby winner Treasure Beach nor French Derby winner Reliable Man could produce his best form Thursday in the Grand Prix de Paris, and it was unheralded Meandre up late under Maxime Guyon to catch pacesetting Seville in the final furlong.

The undefeated Reliable Man will have three Aidan O’Brien-trained runners, headed by Irish Derby winner Treasure Beach, among his opponents Thursday in an appealing edition of the Group 1 Grand Prix de Paris at Longchamp.

Dream Ahead, the English joint champion 2-year-old of 2010 with the undefeated Frankel, gave jockey Hayley Turner her first win in a Group 1 race in Saturday’s July Cup at Newmarket, England.

Making his second start of 2011, Dream Ahead (7-1) rallied between horses through traffic to win by a half-length over Bated Breath. Star Witness, the 4-1 favorite, finished 10th of 16. Delegator, unplaced in the last two runnings of the Breeders’ Cup Mile, finished fifth.

The winning colors flashing home first at the finish of the Falmouth Stakes on Friday at Newmarket were familiar. The horse beneath them? Not so much.

Frederick Engels extended his stakes-winning streak to two races, and the mare Crystal Capella won her first career stakes against males in Group 2 stakes at Newmarket, England, on Thursday.

Frederick Engels, sent off at 7-4, won the six-furlong July Stakes by a length over 6-4 favorite Roman Emperor. Ridden by Eddie Ahern, Frederick Engels was always near the front and took the lead in the final furlong, holding off the favorite. Bannock finished third in the field of seven.
