French invader Natagora will pit her speed against a fast-improving Infallible in the 195th running of the 1000 Guineas Stakes at Newmarket on Sunday when 15 fillies contest the $696,000 classic mile.

New Approach will put his spotless record on the line at Newmarket on Saturday in the 200th running of the 2000 Guineas Stakes.

The European champion juvenile, New Approach will be making his first start of the season in the $696,000 mile classic, but trainer Jim Bolger should have his Galileo colt ready for the biggest race thus far in his career.

Owner William J. Preston appears to have himself a hot prospect for the French Oaks in Leo's Starlet. A homebred Galileo filly, bred in Ireland by Prestonwood Farm, Leo's Starlet extended her unbeaten record to 3 for 3 at Saint-Cloud on Thursday by winning the $125,000 Group 3 Cleopatre, a key 1 5/16-mile prep for the Oaks.

Nownownow will not run in the 2000 Guineas at Newmarket on Saturday, as he was withdrawn from the race at the five-day entry stage by trainer David Wachman, who offered no explanation.

Winner of last year's Breeders' Cup Juvenile Turf, Nownownow had missed his intended Guineas prep race because rain had set him back a bit. A son of Whywhywhy owned by Fab Oak Stables, Nownownow is stabled at Wachman's yard in County Tipperary in Ireland.

Good Ba Ba swept to victory in the $1 million Champions Mile at Sha Tin on Sunday, virtually clinching Hong Kong Horse of the Year honors in the first foreign race to be included in the Breeders' Cup's Win and You're In program.

But Good Ba Ba, a 6-year-old Kentucky-bred son of Lear Fan, is most unlikely to be at Santa Anita for the Breeders' Cup Mile, even though he is fully nominated to the Cup.

Duke of Marmalade followed in the footsteps of his former stablemate Dylan Thomas and won the Group 1 Prix Ganay at Longchamp on Sunday. An Irish-bred Danehill 4-year-old, Duke of Marmalade was winning for the first time in seven starts since his maiden victory in June 2006, but he has now positioned himself for all of Europe's best races between a mile and 10 furlongs.

Centennial led virtually throughout to capture the Group 3, $89,000 Sandown Classic Trial at Sandown Park on Saturday, holding off the late challenge of Whistledownwind by a short neck.

Sent off as the 6-5 favorite, Centennial was two lengths clear at the eighth pole, but his rider, Jimmy Fortune, had to get down to work when Whistledownwind loomed up alongside. It was another 1 1/4 lengths back to Feared in Flight in third.

Good Ba Ba can earn himself a spot in the Breeders' Cup Mile on Sunday should he prevail as expected in the $1 million Champions Mile at Sha Tin. The first foreign race to be run as part of the Breeders' Cup' Win and You're In program, the Group 1 Champions Mile shares top billing in Hong Kong with the $1.8 million Queen Elizabeth II Cup, in which Viva Pataca will seek redemption following his second-place finish in the Dubai Sheema Classic.

Mrs. Lindsay can add her name to a list of female Prix Ganay winners that includes Aquarelliste, Triptych, and Trillion on Sunday at Longchamp. A 4-year-old Theatrical filly owned by Bettina Jenney of Pennsylvania, Mrs. Lindsay will be perfectly suited by the conditions of the Ganay, a 1 5/16-mile Group 1 contest worth $470,000.

The road to the Epsom Derby begins in earnest at Sandown Park on Saturday when Centennial will attempt to improve upon a promising juvenile campaign in the Group 3, $99,000 Sandown Classic Trial, a 1 1/4-mile prep for the 1 1/2-mile Derby.

Trained by John Gosden, Centennial followed a victory in the Haynes, Hansen & Clark Conditions Stakes at Newbury last fall with a very good second to French champion juvenile Thewayyouare in the Group 3 Prix Thomas Bryon. Both of those races were at a mile.
