Five first-season sires that have made a flying start at stud
Red Jazz, Society Rock and Havana Gold all quick off the mark
Johannesburg-Now That's Jazz (Sword Dance)
Monday's racing saw Red Jazz join Society Rock at the top of the first-season sires' table by number of winners after Jedi Master broke his duck in a 6f novice auction stakes at Thirsk to become a sixth winner for his sire.
Other runners from his first crop of 102 foals to have won include the Richard Hannon-trained Mutanaaseq, winner of two novice contests, and the Denis Coakley-trained Electric Landlady, who was a two-length winner on her only start at Kempton in May.
Red Jazz himself was a smart juvenile, winning two races over the minimum trip and finishing third in the 6f Group 2 July Stakes, and it looks as though his progeny have inherited that same precocity.
Trained by Barry Hills, Rad Jazz developed into a high-class seven-furlong colt at three, winning the Listed Free Handicap and the Group 2 Challenge Stakes at Newmarket, a race record that is sure to give hope that his sons and daughters can keep on progressing.
The son of Johannesburg stands at Ballyhane Stud at a fee of €4,000.
Rock Of Gibraltar-High Society (Key Of Luck)
The Johnny Murtagh-trained Yolo Star and Roger Varian-trained Dahik have also impressed, and with Society Rock's first crop containing 120 foals, there should be plenty more to come from the late Tally-Ho Stud resident.
While he may be remembered as an older sprinter, and also for his on-course rivalry with fellow freshman sire Lethal Force, the James Fanshawe-trained Society Rock was no slouch at two, winning a 6f maiden and a valuable sales races over the same distance.
The son of Rock Of Gibraltar was retired to Tally-Ho Stud in 2014, but sadly succumbed to laminitis in May 2016.
Teofilo-Jessica's Dream (Desert Style)
Havana Gold was the first paternal grandson of Galileo to supply a winner when Havana Grey scored at the second attempt in a 5f maiden at Ayr in May.
That same grey colt was also the first stakes winner for Havana Gold - the first of any freshman sire this year - when he followed up with a length victory in the Listed National Stakes over the same trip at Sandown later in the month.
Other winners from that first crop of 104 foals include Treasuring, who got off the mark at Navan on Saturday, and Headway, winner of a 6f maiden at Chester at the end of May.
Trained by Richard Hannon, Havana Gold was a high-class juvenile, winning the 7f Group 3 Somerville Tattersall Stakes at Newmarket, before going on to win the mile Prix Jean Prat at Chantilly at three.
The son of Teofilo was retired to Tweenhills Farm and Stud, and was availbele to breeders in 2017 at a fee of £7,000.
Invincible Spirit-Swiss Lake (Indian Ridge)
Swiss Spirit became the first from the freshman Class of '17 to sire a winner when son Kick On Kick On did exactly that on debut at Leicester in early-April.
Since then, Swiss Spirit has continued to sire winners from a crop of just 76 foals, including the Michael Bell-trained Joe's Spirit - a gutsy winner at Chelmsford - and the impressive Wolverhampton winner Awsaaf, who is in the care of Simon Crisford.
Trained in the earlier part of his racing career by David Elsworth, Swiss Spirit did not set the world alight immediately, winning only in a 6f maiden on his second of four starts as a juvenile, before winning the 6f Listed Carnarvon Stakes at Newbury at three, where he defeated Lethal Force.
Switched to John Gosden at four, Swiss Spirit continued to improve, and was second in the Temple Stakes at Haydock and the King George Stakes at Goodwood, both Group 2s.
The son of Invincible Spirit was retired by owner-breeder Lordship Stud to stand at Whitsbury Manor Stud, where his fee in 2017 is £4,000.
Hat Trick-Rumored (Royal Academy)
An unbeaten champion two-year-old in France, Dabirsim's precocity seems to have been passed on to his sons and daughters, as four of his five runners to date have won, while the other, Mysterieuse, was placed.
Different League is perhaps the best of those, having won twice already, including in a 6f Class 2 contest by two lengths at Lion d'Angers.
Trained by Christophe Ferland, Dabirsim won the 6f Prix Morny and 7f Prix Jean-Luc Lagardere in a remarkable two-year-old campaign, but did not show quite the same spark at three, his best of two runs when a short-head second in the Group 3 Prix de Fontainebleau.
The son of Hat Trick stood his first two seasons at Gestut Karlshof in Germany, before he was relocated to Haras de Grandcamp in France, where he remained at a fee of €9,000.
