Pedigree fun facts: 2026 Kentucky Derby

Apr 27, 2026 Kellie Reilly/Brisnet.com

Breed-shaper Northern Dancer, the 1964 Kentucky Derby champion, is ubiquitous in modern pedigrees

Can perennial leading sire Into Mischief deliver a record-breaking fourth Kentucky Derby (G1) winner? Will Nyquist join the ranks of Derby winners to sire a Derby winner? Or might Essential Quality tie the record as the youngest stallion to come up with a Derby winner?

These are just a taste of the pedigree feast to be served in the 152nd edition of the Kentucky Derby at Churchill Downs on Saturday.

Into Mischief has three realistic chances including the favorite

Not only does Into Mischief have three sons in the 2026 Derby field, but two of them are at the head of the projected betting for Derby-winning trainers.

Hall of Famer Todd Pletcher’s Renegade is the 4-1 favorite on the morning line, and Brad Cox’s Commandment is listed as the joint second choice at 6-1. Even Into Mischief’s double-digit contender, Potente (20-1), has credentials for Hall of Fame trainer Bob Baffert, who is tied for the record for most Derby wins with six. If Potente can spring an upset, he would help to set two new records simultaneously, in both the trainer and sire categories.

Baffert trained Into Mischief’s first Derby hero, Authentic (2020), and Cox had his second, Mandaloun (2021), who was promoted via disqualification. Into Mischief is the only stallion so far to sire back-to-back winners. Since he earned his record-tying third victory with Sovereignty last year, Into Mischief will try to equal his own unique feat with another back-to-back pairing.

Moreover, Into Mischief is the paternal grandsire of Mystik Dan, the 2024 Derby upsetter, by Goldencents. Another son of Into Mischief, Maximus Mischief, hopes to land a blow of his own with the 50-1 longshot Intrepido.

Nyquist aims to make it a baker’s dozen for Derby-winning sires

Twelve Derby winners have had sons emulate them in the Run for the Roses, but none since Unbridled (1990) joined the club courtesy of Grindstone (1996). Nyquist, the 2016 Derby champ, would become number 13 if Litmus Test (30-1) can engineer a form reversal for Baffert.

Other Derby-winning sires and sons are Triple Crown legend Seattle Slew (1977) and Swale (1984); the great Swaps (1955) and Chateaugay (1963); Determine (1954) and Decidedly (1962); a three-generation streak from Pensive (1944) to Ponder (1949) to Needles (1956); the original triple play of Reigh Count (1928) to Triple Crown romper Count Fleet (1943) to his son, Count Turf (1951); Bold Venture (1936), who sired two successors in Triple Crown sweeper Assault (1946) and Middleground (1950); Gallant Fox (1930), still the only Triple Crown winner to sire a Triple Crown winner in Omaha (1935); Bubbling Over (1926) and Burgoo King (1932); and Halma (1895) and Alan-a-Dale (1902).

Eight-year-old Essential Quality can strike with a first-crop son

Nyquist’s victory propelled his own sire, Uncle Mo, into the record book as one of the youngest stallions to come up with a Derby winner. Uncle Mo was eight years old when Nyquist won. This year, Essential Quality can add his name to the select list of eight-year-old stallions to celebrate a Derby-winning son, if The Puma prevails.

Essential Quality, the 2020 Breeders’ Cup Juvenile (G1) champion, was the undefeated favorite going into the 2021 Derby. He lost his perfect record when beaten a grand total of a length as the official third-placer, but reiterated his divisional leadership with victories in the Belmont (G1) and Travers (G1).

Retired to stud as a four-year-old, Essential Quality had his first foals arrive when he was five. That first crop is now three years old, making him eight.

Eight-year-old sires are the youngest in the Derby annals because they followed the same pattern of retiring at four and striking with a first-crop winner. Other eight-year-old stallions to celebrate Derby-winning progeny are Gallant Fox, sire of Omaha; Pensive, sire of Ponder; Royal Coinage, sire of Venetian Way (1960); Raise a Native, sire of Majestic Prince (1969); Maria’s Mon, thanks to his first Derby hero, Monarchos (2001); Bodemeister, sire of Always Dreaming (2017); and Mage, sire of Good Magic (2023), whose connections overlap with The Puma’s.

Sire lines represented

Breed-shaper Northern Dancer, the 1964 Derby star, has the most male-line descendants in the 2026 field. Nine of the 24 entrants (including the four also-eligibles) hail from his sire line.

Into Mischief, a scion of the Storm Cat branch, factors in four of those nine (including paternal grandson Intrepido). Hot young sire Not This Time, who has Six Speed in the Derby, also descends from Storm Cat. But Not This Time comes via another path, by Storm Cat’s son Giant’s Causeway, the “Iron Horse.” So does Pavel, sire of Derby contender Pavlovian.

The other three Northern Dancer-line hopefuls represent the Sadler’s Wells branch via Medaglia d’Oro. Incredibolt and the fourth also-eligible, Corona de Oro, are both by Bolt d’Oro, who was 12th behind Justify in the 2018 Derby. The first on the also-eligible list, Great White, is by the brilliant sprinter Volatile.

Seven of the entrants are by Mr. Prospector-line stallions. Japan Road invitee Danon Bourbon is a Kentucky-bred by Maxfield, himself a son of 2007 Derby champion Street Sense. Hall of Famer Curlin, third in Street Sense’s Derby, sends out Golden Tempo. Curlin’s son Connect has also-eligible Ocelli. Another also-eligible, Robusta, is by champion Accelerate. Hall of Famer Gun Runner, third in Nyquist’s Derby, is responsible for Further Ado. Gun Runner’s own sire, Candy Ride, has Emerging Market. Liam’s Map, from the male line of Derby hero Unbridled, relies on Fulleffort.

Mr. Prospector’s sire, Raise a Native, has a distinct, less numerous branch via his Derby-winning son, Majestic Prince. This is the tribe responsible for So Happy, who could count as an eighth contender for the broader Raise a Native sire line if you expand it beyond “Mr. P.” So Happy is by champion sprinter Runhappy, a son of 2010 Derby hero Super Saver.

Four entrants fly the flag of the Seattle Slew sire line, propagated by his Hall of Fame son, A.P. Indy, all via the influential Tapit. Essential Quality is a son of Tapit, as is Tacitus, who has a first-crop hopeful in Silent Tactic. The established Tapit stallion Constitution has two sons in the field, Chief Wallabee and longshot Right to Party.

Two contenders are grandsons of Uncle Mo, a rejuvenation of the male line of *Nasrullah as expressed by Caro. In addition to Nyquist’s Litmus Test, Yaupon is a son of Uncle Mo who has furnished Albus in his first crop.

Japan-based Wonder Dean fittingly traces to Hall of Famer Sunday Silence, the 1989 Derby and Preakness (G1) star who remade the Japanese Thoroughbred in his image. Wonder Dean is by Dee Majesty, a son of the legendary Japanese Triple Crown winner Deep Impact.

Female-line heritage runs deep

Commandment’s mother, Sippican Harbor, is by 2013 Derby winner Orb. Sippican Harbor captured Saratoga’s most prestigious race for two-year-old fillies, the Spinaway (G1), in 2018. Her female line, numbered 16-g, traces to the ancestress of 1942 Derby, Belmont, and Travers victor Shut Out.

Litmus Test is out of Study Hard, who’s by the same sire as Orb, Malibu Moon. Study Hard’s maternal line, labeled 4-m, is responsible for a handful of Derby winners – Day Star (1878), Lawrin (1938), Middleground (1950), Venetian Way (1960), and Sunny’s Halo (1983).

Silent Tactic’s mother, the Gun Runner mare Magical Sign, is out of a full sister to Malibu Moon. Silent Tactic shares the same ancestress as 1973 Triple Crown legend Secretariat. Both are direct female-line descendants of British import *Cinq a Sept. A member of the 2-s family, *Cinq a Sept won the 1927 Park Hill S. at Doncaster – the fillies’ equivalent of the world’s oldest classic, the St Leger.

Wonder Dean is out of a mare by Wonder Acute, a son of 1999 Derby and Preakness winner Charismatic. Wonder Acute was a prolific dirt campaigner in Japan who bankrolled more than $9.6 million during his lengthy, 48-race career.

Emerging Market is out of a half-sister (by Empire Maker) to 2009 Breeders’ Cup Juvenile Fillies (G1) champion She Be Wild. Empire Maker, runner-up as the 2003 Derby favorite, is also the maternal grandfather of Derby awardee Mandaloun (2021). Himself by Derby champion Unbridled, Empire Maker factors as the paternal grandsire of two other Derby stars, American Pharoah and Always Dreaming (2017).

Bernardini, the maternal grandfather of last year’s Derby champion Sovereignty, plays the same role in the pedigrees of Albus and Golden Tempo.

Albus is out of the Bernardini mare Adream, from the immediate family of champion Malathaat, the 2021 Kentucky Oaks (G1) and 2022 Breeders’ Cup Distaff (G1) winner. They belong to the maternal line labeled 1-n, like Derby scorers *Tomy Lee (1959), Swale (1984), and the filly Genuine Risk (1980).

Golden Tempo is out of the Grade 3-winning Bernardini mare Carrumba, who hails from the family of Hall of Famer Heavenly Prize. Diving deeper into the female line, dubbed 20-b, one finds that 2002 Derby upsetter War Emblem traces to the same ancestress.

Renegade’s mother, Grade 3 heroine Spice Is Nice, is bred on the same cross as Golden Tempo. Her parents are Curlin and the Bernardini mare Dame Dorothy, whose most significant victory came on Derby Day 2015 in the Humana Distaff (G1).

Pavlovian is out of a mare by Bellamy Road, the 17 1/2-length conqueror of the 2005 Wood Memorial (G1) who faded to seventh as the Derby favorite. Pavlovian’s maternal line, the 13-c family, has produced Derby winners Jet Pilot (1947), Ferdinand (1986), and Seattle Slew. They all descend from the fine filly Frizette, commemorated by the Grade 1 stakes in New York.

Right to Party also comes from a storied maternal line, labeled 17-b, whose Derby stars include Triple Crown winner Omaha, Johnstown (1939), and Decidedly (1962). Right to Party’s mother is by the Unbridled’s Song stallion Emcee, from the immediate family of Canadian Horse of the Year Wonder Gadot.

Danon Bourbon is out of a Tapit mare belonging to the 12-c matrilineal tribe. He has a remote ancestress in common with Brokers Tip, who broke his maiden in the “Fighting Finish” of the 1933 Derby and never won again.

Further Ado’s mother is the Grade 3-placed Sky Mesa mare Sky Dreamer. She is out of a mare whose parents are 2001 Derby winner Monarchos and champion Beautiful Pleasure, heroine of the 1995 Breeders’ Cup Distaff.

The Puma’s female line belongs to the 4-r family that’s responsible for Monarchos and five other Derby winners – Halma (1895), Manuel (1899), Donau (1910), Black Gold (1924), and most recently Mystik Dan (2024). The Puma’s mother is by Declaration of War, a multiple Group 1 winner on the British turf who just missed when third in the 2013 Breeders’ Cup Classic (G1).

Intrepido is out of a mare by Pleasantly Perfect, hero of the 2003 Breeders’ Cup Classic and 2004 Dubai World Cup (G1). By 1981 Derby and Preakness champion Pleasant Colony, Pleasantly Perfect is out of Group 1 queen Regal State, a daughter of 1978 Triple Crown sweeper Affirmed.

Medaglia d’Oro, runner-up to Pleasantly Perfect in the Breeders’ Cup and in Dubai, appears as the maternal grandfather of both Six Speed and Chief Wallabee.

Six Speed’s mother, stakes-placed Browse, is a half-sister to Grade 1 turf star Imagining, from the family of Derby scorer Super Saver (2010). Six Speed thus belongs to the famed female line established by *La Troienne, numbered 1-x, that also claims Derby winners Sea Hero (1993), Go for Gin (1994), and Smarty Jones (2004).

Awesome Again, who won the vintage 1998 Breeders’ Cup Classic at Churchill Downs, has three grandsons in the main body of the field – Incredibolt, Potente, and Fulleffort.

Incredibolt descends from the blue hen Lassie Dear, the grandmother of A.P. Indy. This is another subset of the 3-l family responsible for 1948 Triple Crown legend Citation and Silver Charm, who came agonizingly close to sweeping the three jewels in 1997.

Potente is a grandson of 2000 Breeders’ Cup Filly & Mare Turf (G1) champion Perfect Sting. Fulleffort is a half-brother to Power Squeeze, the 2024 Alabama (G1) victress who was sixth in that year’s Kentucky Oaks.

So Happy is likewise out of a mare by a famous Breeders’ Cup Classic winner at Churchill. His mother is by Blame, who thwarted Zenyatta’s perfect record in the 2010 edition.

So Happy’s female line belongs to the A15 family that produced 1882 Derby winner Apollo. You might have heard of him in times past as the only unraced juvenile who went on to take the Derby, giving rise to the “Apollo curse” against contenders who had not raced at two. But that stat has been defied by both Justify and Mage in recent years.

Of the four also-eligibles, Robusta is most notable as a member of the 17-b tribe (like Right to Party) with success close up on his page. He is out of an Into Mischief mare who is a half-sister to millionaire Suave. Robusta’s grandmother is multiple Grade 1-winning millionaire Urbane, the runner-up in the 1995 Kentucky Oaks.

Great White is out of a mare by Uncle Mo, who is also the maternal grandfather of last year’s Derby runner-up Journalism. Ocelli’s mother is by Scat Daddy, the sire of Justify. And Corona de Oro is out of a mare by champion Lemon Drop Kid, the 1999 Belmont winner.
