Look Here can claim a spot in the Breeders' Cup Filly and Mare Turf with a victory in the Group 1, $348,000 Pretty Polly Stakes at the Curragh on Saturday. The winner of last year's English Oaks, Look Here was an eye-catching third in the Group 1 Coronation Cup three weeks ago at Epsom, losing by a pair of noses to Ask and Youmzain, and is expected to improve again in what will be just her sixth career star in this Win and You're In Breeders' Cup event.

Cannonball suffered a heartbreaking defeat in the Group 1, $742,000 Golden Jubilee Stakes at Royal Ascot on Saturday as the 20-1 longshot Art Connoisseur held him safe by a neck to land a sizzling hot renewal of the six-furlong sprint.

Ghanaati won the battle of the 1000 Guineas winners at Royal Ascot on Friday with a record-setting performance in the Group 1, $408,000 Coronation Stakes.

Three 1000 Guineas winners help to make the $410,000 Coronation Stakes the race of the week at Royal Ascot on Friday, when each of the 12 entries in the one-mile Group 1 for 3-year-old fillies has a proper claim on first prize.

Fillies of the juvenile sort will also line up for the Group 3 Albany Stakes in which the best of trainer Wesley Ward's 2-year-olds, Aegean, will attempt to follow up on the historic victories of Strike the Tiger and Jealous Again earlier in the week.

Wesley Ward electrified Royal Ascot on Wednesday as his juvenile filly Jealous Again led throughout in a scintillating display of speed to win the Group 2, $147,000 Queen Mary Stakes by five handy lengths. Her astounding performance in what some British observers had called the best Queen Mary in the last 10 years came just a day after Ward had made history by saddling the first American-trained horse to win a race at Ascot in Strike the Tiger.
