2023 Mating Plans, Presented by Spendthrift: Edwin Anthony, Shortleaf Stable

As we approach the opening of the 2023 breeding season, the TDN staff is once again sitting down with leading breeders to find out what stallions they have chosen for their mares, and why. Here's what Edwin Anthony of Shortleaf Stable had to say about their broodmare band for 2023.

I subscribe to the same school of thought as pedigree gurus like Ken McLean, Alan Porter and Anne Peters when it comes to trying to concentrate the influence of the most effective foundation mares and families. My first job in the horse business (after hotwalker) was doing pedigree research for journalist and consultant Bill Oppenheim at Racing Update, so I learned to compile databases and the importance of recognizing patterns.  During that time, I also got to know Roger Lyons, who helped to build the CompuSire computer program for looking at hypothetical matings back to the sixth generation, which I still use.

Using those tools, skills, and nearly 40 years of my own research and experience, I'm able to work with my father (owner of Shortleaf Stable) in arranging our mare bookings each season. It's always a good idea to keep an open mind and look at all parts of a mare's pedigree to forecast what might work for her. You also want to incorporate some common sense regarding size, soundness, speed, stamina and keeping your long-term goals in mind, including staying within a realistic budget. Shortleaf races all of the stock that we breed, so we have a ceiling on what we're willing to spend on each stud fee, since we'd like to see the resulting foal earn back as much of our investment as it can.

PANGBURN (m, 11, Congrats—It's True Love, by Yes It's True), booked to Good Magic

We raced this mare after purchasing her as a yearling. She's a big mare, but was precocious and a very sound racehorse, placing in several graded stakes. She has been a good match for Hard Spun (dam of SW Caddo River by him and a just-turned 2-year-old full-brother that is one of our top prospects), so we decided to send her to GOOD MAGIC, who is out of a mare by Hard Spun. Curlin (sire of Good Magic) has an outstanding record on the A.P. Indy cross, and I have concentrated on Hard Spun's blood with her because he carries Roberto and she carries Dixieland Band. When they are combined in pedigrees, you get linebreeding to full-sisters, and I have seen that combination work with great success for decades. It just keeps working.

BENNER ISLAND (m, 9, Speightstown—Spacy Tracy, by Awesome Again), booked to Bolt d'Oro

This mare was another yearling sale purchase and was very fast and classy, winning a Grade II on Derby Day, sprinting. We like to send her to stallions that would logically add some stamina. The obvious choice would be Medaglia d'Oro, since he has nicked so well with Speightstown in pedigrees, but he's always been out of our price range. Since he was so popular at the sales and showed some good results with his first crop of runners, we elected to go with Medaglia d'Oro's son BOLT D'ORO, who is out of a mare by A.P. Indy, which should add some stamina genes as well. In addition, Bolt d'Oro is from the Sadler's Wells sire line and Benner Island carries Nureyev, so having those three or four brothers in a pedigree can't hurt, since they have combined so well.

REEF POINT (m, 10, Giant's Causeway—Dixie City, by Dixie Union), booked to Daredevil

Yet another yearling purchase, this mare didn't have much interest in being a racehorse, but she is from the family of Dehere, out of a Grade II winner, and by a leading broodmare sire, so we never hesitated in spending money on her stud fees. She is the dam of MGSW Bubble Rock (on turf), by More Than Ready. That was an easy mating to come up with given all of the success that More Than Ready has had in reinforcing the influence of Almahmoud through her grandsons Northern Dancer and Halo. There are numerous examples of combining stallions with inverted pedigrees, achieving “balanced” inbreeding/linebreeding through sons and daughters of the same ancestors. This is achieved when you cross Southern Halo (son of Halo, daughter of Northern Dancer) with Giant's Causeway (carries a son of Northern Dancer and a daughter of Halo). Since More Than Ready is no longer with use, a good choice for this mare was More Than Ready's son, DAREDEVIL. He's out of a mare by Forty Niner, who is in turn out of a mare by Tom Rolfe (a son of the notable mare Pocahontas). Giant's Causeway carries Tom Rolfe's half-brother Chieftain, and I have seen linebreeding to Pocahontas and the more general family of The Squaw II (Ack Ack, Sham, etc.) work on numerous occasions. 

HOLIDAY'S JEWEL (m, 14, Harlan's Holiday—Denali Red, by Crafty Prospector), booked to Twirling Candy

We bought this mare as a maiden at the Keeneland November Sale. She was a sound campaigner in New York (made 40 starts) and had plenty of stamina. She was another mare in a good position to take advantage of linebreeding to Almahmoud (Halo, Northern Dancer), so we sent her to More Than Ready several times and were rewarded with the GSP filly Caldee from that union. I recognized that she had some other interesting ancestors that made her a good match for Candy Ride's son TWIRLING CANDY, and we have been anxious for our breeding program to have more exposure to Candy Ride's growing influence, so we decided to go that direction with her. Twirling Candy was the choice because Harlan's Holiday is out of a mare by Triple Crown winner Affirmed and Twirling Candy traces to the dam of Affirmed, Won't Tell You (his fifth dam). Harlan's Holiday is also from the important Alanesian/Alablue family and Twirling Candy has three crosses of that family close up in his pedigree–via Ride the Rails and Cryptoclearance (sire and grandsire of Candy Ride), as well as Boldnesian (grandsire of Seattle Slew).

MERRY MITTENS (m, 13, Harperstown–Weatherfield, by Elusive Quality) booked to Plainsman

This mating is the very definition of “homebred.” We raced the sire Harperstown (SP son of Devil's Bag–Halo, from a mare by Northern Dancer) and stood him in Arkansas. We had a couple of full-sisters by Elusive Quality that we bred that were out of a daughter of our classic winner Pine Bluff (a son of Danzig–Northern Dancer, from a mare by Halo). We've had good luck reinforcing all of this Almahmoud blood (Halo, Northern Dancer) so we bred both of the Elusive Quality mares (with Pine Bluff) to Harperstown. From those unions, we got the very legit GSW Trace Creek (an allowance winner at Churchill and Keeneland) and this mare, an open allowance winner sprinting and the dam of Arkie-bred SW Sekani. She makes a lot of sense for our new stallion PLAINSMAN (a son of Flatter that won three graded stakes for us) since he needs some mares with speed and this mating results in linebreeding to three sets of full-siblings–Devil's Bag and his brother Saint Ballado, Hero's Honor and his sister Wild Applause, and Graustark and his brother His Majesty. We'll know in about four years if it was a good idea.
