New York Filly Triple Tiara

Horseracing’s “Triple Tiara” for fillies takes its name after the “Triple Crown” races. The races had been known as the “Filly Triple Crown” since at least 1961. The name was changed to the “Filly Triple Tiara” in 1988.
 
The three races that constitute the “Triple Tiara” have changed over the years. Since, 2010, the “New York Filly Triple Tiara”  has consisted of The Acorn Stakes (at Belmont Park in Elmont, NY), The Coaching Club American Oaks and The Alabama Stakes (both at Saratoga Race Course in Saratoga, NY).

In capturing the Acorn, the first leg of the New York Racing Association’s Triple Tiara for fillies, Aptostar and Topicount gave Centennial Farms a strong hand for the final two races.

ON HORSE RACING; More Is Amiss With Triple Tiara Than Its Name
By STEVEN CRIST
Published: July 04, 1989
There was a triple crown to be won at Belmont Park yesterday afternoon, but not a Triple Crown, so there were none of the trappings of that upper-cased prize: no record crowd, no crackling anticipation of history in the making, no oversized $1 million bonus check to be won, not even a shiny new sedan parked in the winner’s circle.
 
Then again, the New York filly triple crown series - the Acorn Stakes, the Mother Goose Stakes and yesterday’s Coaching Club American Oaks - is not even officially a triple crown in name anymore. Two years ago, when the big Triple Crown started flexing its newly incorporated and copyrighted muscles, it was suggested to Belmont Park officials that calling anything but the Triple Crown a triple crown might confuse the public.
 
It is difficult to see how anyone who can spell ‘‘triple,’’ much less bet one, would confuse the Acorn, Mother Goose and C.C.A. Oaks with the Kentucky Derby, the Preakness and the Belmont Stakes. But just to be safe, track officials renamed the fillies’ series the Triple Tiara.

The Triple Tiara
By Teresa Genaro, Hello Race Fans Contributing Editor  
You might be forgiven for not knowing exactly what the Triple Tiara is. Or if it’s the same thing as the Filly Triple Crown. Or for not knowing what, exactly, that is, either.

A high profile series of races for 3-year-old fillies has had a rougher road to recognition: the races it comprises has changed a number of times, as has its name. Firmly establishing a series of races for 3-year-old fillies has been no easy task.

The Tricky Tiara?
August 18, 2011
The poor Triple Tiara.  It’s been poked and prodded and tweaked and changed multiple times in the last half century; it might be the Rodney Dangerfield of Thoroughbred racing.
(...)
1961:  The New York Racing Association names the Acorn, the Mother Goose, and the Coaching Club American Oaks the Filly Triple Crown.
 
1988:  The name of the series is changed from Filly Triple Crown to Filly Triple Tiara (please do read Steven Crist’s 1989 article on this).
 
2003: The Acorn gets the boot and is replaced by the Alabama.
 
2006:  The Acorn resumes its rightful place; the Alabama is out.
 
2010:  The Mother Goose is jettisoned from the series; the Alabama’s back in; TVG sponsors the series and offers a $50,000 bonus to the filly who wins all three races, along with financial considerations for the points accrued in the three races if no filly gets the sweep.
 
2011: TVG’s sponsorship continues, but the bonus is dropped.
