Background Check: Del Mar Debutante

In this continuing series, we examine the past winners of significant filly/mare races by the lasting influence they've had on the breed. Up today is the GI TVG Del Mar Debutante S., a race with a surprising amount of repercussion on the sport.

First run the year before Queen Elizabeth II took the throne, the Del Mar Debutante has seen 72 winners, with D. Wayne Lukas and Bob Baffert together combining for more than a quarter of those visits to the winner's circle. It's been run on Polytrack; it's been run in two divisions; and it's been run at seven-eighths since 1994 after stints at six and eight furlongs. The 2-year-old filly event was officially designated a Grade I in 1999.

With the storied history and sheer volume of big-league filly/mare contests focused at Saratoga over the summer, other tracks–even those as spectacular as Del Mar–can be overshadowed. But every now and then a race, like the Del Mar Debutante, has a list of past winners that pops up on the radar. While not all of the Debutante's victresses have been stellar broodmares, there have been a few that have more than held their own. The list may not be long, but it's top notch.

Following are the some of the most important Del Mar Debutante winners by what impact they have had on the breed through their sons and daughters.

Althea (1981, Alydar–Courtly Dee, by Never Bend): A champion 2-year-old who died at just 14 in a paddock accident, this mare–bred by the partnership of Helen Groves, Helen Alexander, and David Aykroyd–produced four stakes winners from her five foals, including Japanese champion Yamanin Paradise and GSW Destiny Dance. Her daughters and granddaughters have been responsible for GISW and influential sire Arch, U.S. champion Covfefe, UAE champion Festival of Light, and GISWs Acoma and Balletto (UAE). From an extended family that just keeps giving, it's all but a certainty that even more will bubble to the surface as time goes by from Althea's branch of her Broodmare of the Year dam.

Terlingua (1976, Secretariat–Crimson Saint, by Crimson Satan): There a substantial list of stakes performers who trace to this Tom Gentry-bred chestnut, including MGISW Ticker Tape (GB), English G1SW Crowded House (GB), and French G1SW Brando (GB), but it's her GISW son, Storm Cat, who launched a legacy. Christened the leading sire, broodmare sire, and juvenile sire in the U.S.–all multiple times–he simply redefined the breed. After standing for multiple years at $500,000 as the premier sire in the land, Storm Cat has left reverberations still felt today even though he was pensioned 14 years ago and died a few years later.

Brown Berry (1960, Mount Marcy–Brown Baby, by Phalanx): This C. V. Whitney-bred mare is a bit of an outlier, as it would be a challenge to find her in any top pedigrees of today. However, as one of history's rare broodmares to produce more than one Classic winner–and on each side of the Atlantic, to boot–she surely deserves a mention. Her son Avatar won the 1975 GI Belmont S. (and two other Grade Is) and another son, Hours After, won the 1988 G1 Prix du Jockey Club. She also produced two other major stakes winners, as well as five more stakes performers.

Tonga (1949, Polynesian–Tirl, by Tick On): Winner of the very first Del Mar Debutante, Tonga didn't have a single stakes winner among her five foals. However, one of her daughters produced three black-type winners and daughters who would beget, among others, GI Kentucky Oaks winner Gal in a Ruckus, MGISW Habibti, and Canadian Broodmare of the Year No Class, who would be the foundation mare of Sam-Son Farm. The long list of Canadian champions produced by No Class and her daughters include Classy 'n Smart, Sky Classic, and Regal Classic, while her granddaughter Dance Smartly was also a U.S. champion and her grandson Smart Strike was a two-time leading sire in the U.S. whose son, two-time Horse of the Year Curlin, is among the top sires in the U.S. Not a year goes by without the far-reaching effect on both sides of the border of No Class.
