Seventy-four stallions at Australia's Eastern Creek quarantine facility have undergone a second round of testing for equine influenza after one of them had a positive result from initial testing, Australia's federal agriculture minister said Thursday.

Breeders' Cup clues will abound at Ascot on Saturday when Henrythenavigator, Tamayuz, and Raven's Pass clash in the Queen Elizabeth II Stakes, a Group 1 mile valued at $461,000 in which the winner receives an automatic berth in the Breeders' Cup Mile. Two other races on the card also are Win and You're In events, the Fillies Mile for the Juvenile Fillies Turf and the Royal Lodge Stakes for the Juvenile Turf.

New Approach, winner of the Epsom Derby and Irish Champion Stake, will bypass both the Prix de l'Arc de Triomphe and the Breeders' Cup Classic in favor of the Champion Stakes at Newmarket on Oct. 19, his trainer, Jim Bolger, said Monday.

The decision is another blow to the Arc, which lost Prospect Wells and Saddex last week. Last month it lost Montmartre, whose Grand Prix de Paris victory on July 14 saw him installed as the midsummer Arc favorite. He injured a leg in that race, however, and will not run again this year.

Zarkava confirmed favoritism for the Prix de l'Arc de Triomphe at Longchamp on Sunday as she remained undefeated with an impressive victory in the Group 1 Prix Vermeille. Meanwhile, Vision d'Etat maintained his perfect record in winning the Group 2 Prix Niel as Zambezi Sun returned to form with a victory in the Group 2 Prix Foy.

Mastercraftsman maintained his position as Europe's leading 2-year-old at the Curragh on Sunday, but only barely, as he outgamed Shaweel by a short head in taking the $425,000 National Stakes. Victory for the Danehill Dancer colt gave trainer Aidan O'Brien his seventh victory in Ireland's premier juvenile event as well as his 20th Group 1 triumph of the year.

Well, he finally got there. After 25 runners and more than three decades of trying, Sir Michael Stoute won his first St Leger as Conduit scored by three lengths under Frankie Dettori to take the final classic of the British season at Doncaster on Saturday.

An 8-1 chance, Conduit was the second choice of three runners for the stable, with stable jockey Ryan Moore choosing to ride Doctor Fremantle.

Frozen Fire, Aidan O'Brien's Irish Derby winner, was sent off the 9-4 favorite, but never threatened to land a blow from the rear of the field.

Zarkava, undefeated and largely untested in five career starts, will put her classy credentials as favorite for the Prix de l'Arc de Triomphe on the line at Longchamp on Sunday when she returns from a 14-week summer vacation in the Prix Vermeille.

Rainbow View stamped herself as potentially something special at Doncaster on Thursday as she barely came off the bridle in winning big for the third time without a loss in the Group 2 May Hill Stakes.

Rainbow View, current favorite for next year's 1000 Guineas, will step up to Group 2 company at Doncaster on Thursday when she faces seven rivals in the $140,000 May Hill Stakes.

By Dynaformer out of a Del Mar Oaks winner, No Matter What, Rainbow View has won both of her starts by six lengths, the most recent on Aug. 9 in Newmarket's Group 3 Sweet Solera Stakes over the May Hill distance of seven furlongs.

Japan's Prix de l'Arc de Triomphe hopeful, Meisho Samson, will bypass this Sunday's Arc prep for older horses, the Prix Foy, and instead head straight to the Oct. 5 Arc off an improbable 14-week layoff.
