The focus is on 2-year-old racing at Newmarket Racecourse in England this Friday and Saturday, but the juvenile stakes included in the Breeders’ Cup Challenge series are not the most important races during the two days.  Saturday’s program features the Group 1 Cheveley Park for fillies over six furlongs and the Group 1 Middle Park for colts at the same straight-course trip. Also carded is the one-mile Royal Lodge, a Group 2 race that’s a BC Challenge “Win and You’re In” offering automatic fees-paid entry into the BC Juvenile Turf plus travel expenses to Keeneland. Friday’s Group 2 Rockfel for 2-year-old fillies at seven furlongs is a “Win and You’re In” linked to the Juvenile Fillies Turf, and both races often yield Breeders’ Cup runners.  The Royal Lodge drew but four entrants, though the two favorites, Flying Honours and Greenland, are trained, respectively, by Charlie Appleby and Aidan O’Brien, who have combined to win seven renewals of the Juvenile Turf.   Flying Honours is a Godolphin homebred sired by the Godolphin’s signature stallion, Dubawi. Flying Honours finished fourth at even money in his career debut before registering blowout victories in a novice stakes at Sandown and a listed stakes at Salisbury. Godolphin likely has better prospects for races like next year's 2000 Guineas, but Flying Honours has the look of a colt who could be intended for a Breeders’ Cup start, and he merits plenty of attention from an American-based audience in the Royal Lodge. Greenland, from the first crop of his sire, Saxon Warrior, looks less talented, having required four starts to notch a first win, doing so Aug. 29 at Roscommon.   Commissioning is the underlaid early-betting favorite for Friday’s Rockfel having scored a course-and-distance victory by more than three lengths in her lone start to date. The daughter of Kingman is co-trained by the father-son team of John and Thady Gosden, and could have as a main rival Olivia Maralda, second last out in the seven-furlong Debutante, a Group 2 at The Curragh. A dozen others are entered in the Rockfel. Only two European fillies – Chriselliam in 2013 and Flotilla the year before – have won the BC Juvenile Fillies Turf.  The 4-year-old Juvenile Turf Sprint is the newest Breeders’ Cup race, and while Americans have won every renewal, Euros have come in droves. Saturday’s Middle Park and Cheveley Park could offer clues not just for the Juvenile Turf Sprint, but for the Juvenile Turf and Juvenile Fillies Turf.  :: DRF Bets members get FREE DRF Past Performances - Formulator or Classic. Join now! Marshman, racing greenly as the favorite when second last out in the Gimcrack on Aug. 19 at York, was the Thursday favorite for the Middle Park. The race also includes the O’Brien-trained Blackbeard, who already has won five times from seven starts this season. He comes off a victory in the Group 1 Prix Morny, where, as in the past, he acted up pre-race. Persian Force, another Middle Park runner, was second in the Morny, while Appleby and Godolphin – which teamed to beat Marshman in the Gimcrack with Noble Style -- send out Mischief Magic, winner of his last three over lesser competition.  The O’Brien-trained filly Meditate won her first four races before running into the brilliant Tahiyra in the Moyglare Stud Stakes on Sept. 11 at The Curragh. She’s among the shorter prices in the Cheveley Park along with Trillium, a two-time group stakes winner over five furlongs.  * Tahiyra, the most exciting 2-year-old filly seen so far this year in Europe, won’t start again in 2022, her connections announced this week. Trained by Dermot Weld for her breeder, the Aga Khan, Tahiyra will be put away to point for the 1000 Guineas in 2023.  * Possibly owing in part to last week’s announcement that superstar 4-year-old Baaeed would end his career in the Champion Stakes at Ascot rather than the Prix de l’Arc de Triomphe, the connections of Vadeni said the multiple Group 1-winning colt will race in the Oct. 3 Arc. Vadeni won the Prix du Jockey-Club and the Eclipse Stakes before finishing a troubled third Sept. 10 in the Irish Champion Stakes at Leopardstown. Initially ruled out of the Arc following that start, Vadeni instead will race for the first time over 1 1/2 miles in Europe’s most important race next weekend.   * The prospect of good going has led the connections of Adayar, the 2021 Derby winner who has struggled during his 4-year-old season, to consider running in the Arc. Dry conditions, on the other hand, are decidedly not what the connections of 2021 Arc winner Torquator Tasso are seeking. Luxembourg, the Irish Champion winner, is the mild Arc favorite, with England-based 5-year-old mare Alpinista and Japan-based 4-year-old colt Titleholder also well supported in antepost betting.   * Freddy Head announced last week that he will retire from training at the end of the 2022. Head, 75, comes from a famed French racing family and was a celebrated jockey before turning to training. Head rode the mare Miesque to two wins in the Breeders’ Cup Mile and trained Goldikova, who won the BC Mile three years in a row. Head as a jockey won the Arc four times before becoming a trainer in 1997. Besides the legendary Goldikova, Head also trained top-level runners Marchand d’Or, Moonlight Cloud, and Solow. :: Want to learn more about handicapping and wagering?
