The Tattersalls July fillies and mares sale in Newmarket, England, ended its first day Tuesday nearly level with last year. The opening session's highlight was an unraced 3-year-old Pivotal filly named Flag Day who sold for about $182,000 to agent Amanda Skiffington. The session sold 147 horses, two fewer than last year despite a larger catalog, and lost 3 percent in gross. The average price fell 2 percent, and the median remained level with last year. The gross was about $2,883,866, average price was about $19,618, and the median was approximately $7,928. Skiffington bought the session-topping bay filly from Darley Stud on behalf of John Deer's Oakgrove Stud. The filly is out of European champion juvenile filly Blue Duster, by Danzig, and is a half-sister to Group 1 producer Blue Symphony. American breeder Bill McAlpin of Greenwood Lodge Farm bought day's second most expensive mare Cross Section. Darley also consigned the 4-year-old Cape Cross broodmare, who sold in foal to Darley stallion Dubawi. McAlpin, bidding via agent Charlie Gordon-Watson, paid about $174,400. The sale was to continue through July 9.
