Those of us most despondent to see the winner of the first leg sitting out the second can console ourselves, precisely on grounds of tradition, that an abbreviated GI Belmont Stakes would never have allowed a “proper” Triple Crown anyway. Even so, with Curlin obviously deploying a rather more important son at Saratoga this weekend, we can be indulged in neglecting his contribution to one of the more intriguing winners of a relatively quiet week.Original Sin is a slower burn than Golden Tempo, but appears to be thriving with maturity and made a successful black-type debut in the GIII Blame Stakes at Churchill. That's a pretty standard trend for Curlin, and indeed for his sire Smart Strike, and duly augurs well for the continued progress of Golden Tempo.As so often, however, it's his maternal line that makes Original Sin most interesting. True, the foreground is unpromising. His dam Beauty and Light (Unbridled's Song) is described in catalogues as “unplaced in two starts”, but it is more scrupulous to record that she finished last in both. And the next two dams never even made the starting gate.On the face of it, then, it was perfectly excusable for Calumet to cull Beauty and Light from their herd of broodmares when her first foals made little impact. The very first has admittedly won some stakes in Japan but her fifth, a Curlin colt retained for the racetrack program, showed only modest promise when midfield in a Keeneland sprint maiden on debut-just a few days before the Keeneland November Sale of 2024, where Beauty and Light was duly discarded to Saudi interests for just $13,000.Written off pretty comprehensively, then, five years after her $260,000 recruitment in the same ring in January 2019. That price, for a mare who had shown zilch on the track, provides a first clue to the quality of her blood: for her dam Gaudete was a Distorted Humor half-sister to none other than Munnings, whose admirers will know him to belong to one of the most aristocratic dynasties in the book.Now there are times when a single, neglected fact can cast a pedigree in a whole new light. Because on the page it looks as though this branch of his family tree has fallen discouragingly fallow under Gaudete, whose 10 named foals between them mustered a single smudge of black-type. (The first of them had managed a couple of marginal Group placings, one for a subsequently disgraced trainer, in Britain and Dubai.) But while that was plainly disappointing, given the caliber of her covers, the fact is that nine of the 10 were male. In an unusually literal sense, all of Gaudete's eggs were in the single basket of Beauty and Light.And, now, as the solitary strand available to conduct any latent genetic quality to a new generation, she has come up with a graded stakes winner. Original Sin will have to earn plenty more to console Calumet, who washed their hands not only of his dam but also both her daughters, cheaply offloaded the same year. To be fair, farms big and small experience this kind of thing every week. Often, in fact, it's the dread of a disappointing mare suddenly coming good, after being culled, that sustains an expensively misplaced loyalty. In reality, most broodmares that look poor will stay poor. Munnings | Coolmore photoIn this case, admittedly, an extremely tenuous strand connected a mare to some genuinely regal blood. Besides Munnings, Beauty and Light's dam was by definition also sibling to Munnings Sister, who overcame the crushing tedium of her name to win five stakes; and they are out of La Comete (Holy Bull), a half-sister to GI Personal Ensign Stakes winner/Grade II producer Icon Project (Empire Maker) and dual graded stakes winner/Grade I runner-up Lasting Approval (With Approval).The next dam is GI Queen Elizabeth II Challenge Cup winner La Gueriere (Lord At War {Arg}), but even she remains but the tip of the iceberg, as one of several highly talented performers and producers out of Lady Winborne (Secretariat), a half-sister to the great Allez France. And beyond that the class just gets unmanageably intense: Lady Winborne and Allez France were out of the top-class juvenile Priceless Gem (Hail to Reason), herself half-sister to Affectionately (Swaps), three-time champion and dam of a Horse of the Year; and their dam Searching (War Admiral) was a granddaughter of the matriarch La Troienne, who can now duly notch up yet another graded stakes winner in her centenary year. Gems, Pearls and Gold No apologies for revisiting the tale of how Hirsch Jacobs in 1962 was refused a return to Swaps for Searching, winner of 25 races and since admitted to the Hall of Fame. Searching had given Swaps a daughter a couple of years previously, who would shortly turn out to be Affectionately, but John Galbreath couldn't accommodate Searching this time. So Jacobs used his own young stallion, Hail to Reason.When the resulting filly, Priceless Gem, beat Buckpasser in the Futurity Stakes, she had won at Aqueduct in 1:09 4/5 just four days previously. Maybe one of the reasons horses were equal to that kind of campaigning, back then, is because you really had to earn your place in a stallion's book. The quality was locked in.Hail to Reason sired 319 named foals across 15 seasons. As we know, there are totally unproven sires routinely producing that many in their first couple of years. At least the abovementioned Munnings has earned his stripes, elevating himself from an opening fee of $12,500 to a peak of $100,000 in 2023-the graduates of which book are coming into play now. But the fact is that Munnings has so far mustered 1,418 named foals, and two of his six Grade I winners were conceived during his 2011 stud debut. So he's at rather a crossroads, after a solitary graded stakes winner from 390 starters last year, as his $45,000 fee this spring pragmatically acknowledged.Om N Joy winning the Santa Margarita | BenoitIt was auspicious, then, to see his sophomore daughter Betty's Pearl blossoming with a scintillating six-length win in an optional allowance at Churchill. A $700,000 2-year-old, she took five attempts to break her maiden but seems to be flourishing now. Possibly we may see plenty more of this kind of thing, as she belongs to the book assembled by Munnings in 2022 after taking his single biggest hike, from $40,000 to $85,000. She's out of a Tapit half-sister to GI Del Mar Futurity winner Drill (Lawyer Ron), and traces to Darby Dan royalty (fifth dam Luiana (My Babu {Fr}): a sample, no doubt, of the kind of material Munnings has lately been receiving. But in an era of such quantity, the onus is very much on stallions to prove that they can move up their quality so deep into their careers.Another star of his debut book, Om, gave Munnings a different kind of distinction the same day-as grandsire-when his daughter Om N Joy won the GII Santa Margarita Stakes. (On a one-week turnaround: now that's old school!) But we must also give credit to her dam Margie's Minute (Hard Spun), whose previous foal, the 5-year-old Vodka Vodka (Stay Thirsty) is already a Grade I-placed stakes winner this spring. Admittedly finishing second in the Santa Anita Handicap doesn't mean what it once did, but these two homebreds have so far delivered nearly $1.2 million between them.Margie's Minute was apparently the very first horse ever owned by breeders Connie and Jerry Baker, through a $20,000 claim in 2016. And why shouldn't she turn out to be a “Gold Mine”, when her third dam (who bore that name) is a full sister to Mr. Prospector himself! A Sweet Mirror ImageMunnings is of course one of the principal heirs of Speightstown, who further expanded his legacy even on a quiet weekend. His son Maycocks Bay won his first graded stakes in the GII Eclipse Stakes at Woodbine, while that hardy campaigner Lagynos (Kantharos) confirmed Speightstown's prowess as a broodmare sire by winning his fourth in the GIII Arlington Stakes at Churchill. Lagynos has now banked nearly $2.4 million: what an astute pick he has proved, by Chad Schumer at $200,000, out of Book 1 at the 2022 September Sale.Lagynos winning the GIII Arlington Stakes | Coady MediaSpeightstown doubled up an epic distaff brand, both his sire Gone West and damsire Storm Cat famously being out of daughters of Secretariat. And I'm delighted to see another “mirror” mating paying off in Sweet Treasure (Twirling Candy), winner of the GIII Mint Julep Stakes. She's the first starter out of Stellium, a daughter of Empire Maker-whose celebrated dam Toussaud (El Gran Senor) also produced Twirling Candy's damsire Chester House. There are several other echoes in this pedigree, an imaginative play by Don Alberto. Evidently they have now exported the mare to Chile, so let's hope she can build on this promising start there.
