Climate, handling, racing and training styles are all factors that contribute to a somewhat different lifestyle for racehorses and breeding stock in the northern and southern hemispheres and there is no guarantee that a stallion will click in both regions, no matter how outstanding he is in one.
Coolmore Stud's Fastnet Rock is one of the success stories, an Australian sprint star and champion sire who, despite an initially slower than expected start in Europe, has seen his profile here soar over the past two years.
Fascinating Rock, Diamondsandrubies and Qualify all won for him at the highest level in 2015 and, in 2016, the juveniles Intricately and Rivet have added their name to his roll of honour.
His overall global tally stands at 25 Group/Grade 1 winners and, as you might expect of a son of Danehill (by Danzig) and grandson of Royal Academy (by Nijinsky), many of his best progeny represent broodmare sires with strong European and North American connections.
Matching up the Danehill and Sadler's Wells lines is a hugely popular strategy that has produced a lot of success and the Group 1-winning Fastnet Rocks who represent that broad cross are Diamondsandrubies, First Seal, Intricately, Magicool, and Qualify, while those whose broodmare sire represents the Nureyev line (Sadler's Wells's three-parts brother) are Fascinating Rock, Mosheen, Nechita and Rock Classic.
Qualify gave him a European classic success when springing a 50/1 shock in the Group 1 Oaks at Epsom last year and, like her, his current juvenile stars are out of daughters of Galileo (by Sadler's Wells). Intricately won the Group 1 Moyglare Stud Stakes last month and Rivet advertised his classic potential when beating Yucatan by one and three-quarter lengths in the Group 1 Racing Post Trophy at Doncaster on Saturday.
The latter, a William Haggas-trained bay, was bred by Des Scott, he carries the colours of The Starship Partnership, and he has won three of his five starts. Runner-up over six furlongs at Ascot in July, he impressed over seven furlongs at York the following month and then narrowly beat Thunder Snow in the Group 2 At The Races Champagne Stakes over the the same trip at Doncaster in September.
He moved up to a rating of 114 after that success, the colt who finished five lengths further back in third – D'bai – has won a listed contest since – but Rivet disappointed next time when only fifth behind Churchill in the Group 1 Dubai Dewhurst Stakes at Newmarket.
His Group 1 success at Doncaster was achieved on ground that was at least good, if not a bit faster (according to the time analysts), the strength of the competition was some way below what he faced at Newmarket, but he did it well, and with his pedigree this victory greatly increases the likelihood that he will join the stallion ranks whenever his racing days come to an end.
Not only is he by a leading international classic sire, but Rivet is a half-brother to the Group 3 Gallinule Stakes winner and Group 2 King Edward VII Stakes third Alexander Pope, his dam, Starship (by Galileo), is a winning half-sister to juvenile champion Superstar Leo (by College Chapel), and there are two mile classic heroes in his family, both of whom are blacktype sires.
Superstar Leo won the Group 2 Flying Childers Stakes and Group 3 Norfolk Stakes, she was runner-up in the Group 1 Phoenix Stakes, and it was her performance in the Group 1 Prix de l'Abbaye de Longchamp that sealed her championship title. She chased home Namid that day and had the previous month's Group 1 Sprint Cup star Pipalong three lengths behind in third.
Superstar Leo is the dam of the listed scorer and Group 3 Jersey Stakes runner-up Sentaril (by Danehill Dancer) and of the Group 3 King George Stakes and Group 3 Molecomb Stakes heroine Enticing (by Pivotal), and in addition to Starship, her siblings include New York (by Danzero), a non-winner whose son December Draw (by Medecis) won the Group 1 Turnbull Stakes over 10 furlongs at Flemington five years ago.
Like that latter relation, Rivet should stay a mile and a quarter next season and given how he won over the mile at two, the record of his half-brother and being a representative of the Fastnet Rock-Galileo cross, one might presume that he will stay the Derby distance too.
But will he?
His triple-winning dam was well-beaten the twice she ran beyond eight and a half furlongs, his sire was a star sprinter, and the best horses in his family were mostly either sprinters or milers, or both.
So what of his other notable relations?
The two classic winners were speed horses, which was not entirely a surprise given the records of their sires, and it should be noted that one of the pair did not run again after his top-level success.
The third dam of Rivet is Dancing Rocks (by Green Dancer), the Group 2 Nassau Stakes heroine who finished third in the Group 2 Coronation Stakes at Ascot and fourth in the Group 1 Yorkshire Oaks before going on to make an impact at stud and, in addition to the non-winning Council Rock – dam of Superstar Leo and Starship - she is best known as being the dam of Glatisant (by Rainbow Quest).
That filly won the Group 3 Prestige Stakes over seven furlongs at Goodwood as a juvenile, she was runner-up in the Listed Joel Stakes at three, and she is the dam of the lightly-raced and undefeated Group 1 2000 Guineas hero Footstepsinthesand (by Giant's Causeway) and his Group 1 Phoenix Stakes-winning half-brother Pedro The Great (by Henrythenavigator).
The latter is at stud in France and had some of his first yearlings on offer this year, and Footstepsinthesand is the internationally successful Group 1 sire whose progeny include Chachamaidee, Shamalgan, Steinbeck (aka Pure Champion) and 2016 group/graded winners Heshem, Kaspersky, Living The Life, and juvenile colt Larchmont Lad, whose Newmarket Group 3-winning form has been working out quite well.
Glatisant, who is also the dam of the Group 2-placed stakes-winning filly Belle D'Or (by Medaglia d'Oro), is a half-sister to the Listed Cheshire Oaks winner and Group 1 Yorkshire Oaks third Rockerlong (by Deploy), to the dual stakes-placed Charlotte Corday (by Kris), and to three others who deserve mention because of what they achieved at stud.
In the case of Pippas Song (by Reference Point), she is the dam of the listed race winners Edinburgh Knight (by Selkirk) and Nightbird (by Night Shift) but it is her grand-daughter who makes her more significant as that talented filly is the US mile Grade 2 scorer Lady Lara (by Excellent Art). Rainbow Goddess, on the other hand, is a full-sister to Glatisant and she is the dam of the Group 3 Queen's Vase scorer Mahler (by Galileo), a horse who is quite closely related to Rivet's dam.
He was runner-up in the Group 1 St Leger at Doncaster, finished third in the Group 1 Melbourne Cup at Flemington, and he is a popular member of the team at Beeches Stud with the Grade 2-winning hurdler Sutton Place among his earliest runners. His profile, however, suggests that he got the stamina of both of his parents, whereas Starship's comparable pace suggests that she did not.
The other notable daughter of Dancing Rocks is Frappe (by Inchinor), a juvenile winner whose string of successful offspring includes three of considerable note.
Thakafaat (by Unfuwain), her first foal, won the Group 2 Ribblesdale Stakes and has successful progeny that include a multiple chase scorer, and that mare's one-time winning half-sister Applauded (by Royal Applause) has produced US listed scorers by the outstanding Green Desert (by Danzig) stallions Oasis Dream and Invincible Spirit.
More notable, however, are the Grade 1 E P Taylor Stakes-winning half-sister and Group 1 Irish Oaks third Curvy (by Galileo) and the young Coolmore Stud stallion Power (by Oasis Dream). He won Listed Marble Hill Stakes, Group 2 Coventry Stakes and Group 1 National Stakes as a juvenile, added the Group 1 Irish 2000 Guineas at three, and is a leading freshman sire whose first crop contains four European stakes winners.
His Group 1-placed pattern-winning son Peace Envoy was reviewed here earlier in the year and that colt has been joined by the pattern-placed Italian stakes winner Biz Power, Saturday's Newbury listed scorer Cristal Fizz, and the Group 3 Worthington's Horris Hill Stakes scorer Pleaseletmewin, who was sold for 450,000gns during today's session of the Tattersalls Autumn Horses in Training Sale in Newmarket. The stallion also has a listed scorer in New Zealand and a daughter who has been listed-placed in Italy and in California.
Rivet is the latest Group 1 winner for leading international sire Fastnet Rock and he is the latest in a long line of top-level winners for the distaff side of his family.
His relations include the classic winners and successful stallions Footstepsinthesand and Power, and although further improvement looks necessary if he too is to win a Group 1 classic, he is a talented colt who should stay 10 furlongs and whose ability to get beyond that will depend likely on whether he has got the speed or stamina contributions from his parents' genetic make-up.
