The only horse since Danzig to top the General Sires List on three occasions, he has also twice topped the 2YO table.

He is the sire of 31 Gr.1 winners worldwide.

If you want to breed a champion, look no further!

Giant’s Causeway’s bloodlines make this three-time champion sire suitable for the majority of American mares. He has hardly any NATIVE DANCER blood and this helps explain why he has enjoyed spectacular success with descendants of MR PROSPECTOR. Giant’s Causeway’s total of Graded winners from Mr Prospector line mares now stands at more than 35, with every prospect of more to come. Seventeen of them are Gr.1 winners, including the 2015 2yo Brody’s Cause.

His four Graded/Group winners out of MR PROSPECTOR mares include Ghanaati, winner of the 1,000 Guineas, and the top turf horse Aragorn. Giant’s Causeway has an impressive total of ten Gr.1 winners out of grand-daughters of Mr Prospector – his dual classic winner Shamardal is out of a daughter of MACHIAVELLIAN, his Coronation Stakes winner Maids Causeway and his high-class turf horse Red Giant are both out of KINGMAMBO mares, his Diana Stakes winner My Typhoon is out of a MISWAKI mare, his Suburban Handicap winner Frost Giant is out of a GONE WEST mare and his Donn H. winner Giant Oak is out of a CRAFTY PROSPECTOR mare. His Gr.1-winning daughters Take Charge Brandi, Internallyflawless, Swift Temper and Carriage Trail are all out of SEEKING THE GOLD mares. KINGMAMBO mares now have eight stakes winners – 17% – from 46 foals by Giant’s Causeway. LODE, another son of Mr Prospector, sired the dam of the Gr.2-winning Argentine import Catch A Flight.

Giant’s Causeway’s 2015 Wood Memorial winner Carpe Diem is his second Graded winner out of mares by UNBRIDLED’S SONG. He has long done well with this FAPPIANO branch, as Gr.1 winner First Samurai has a second dam by FAPPIANO and Gr.1 winner Heatseeker is out of a mare by Fappiano’s son DEFENSIVE PLAY. Fappiano also sired the dam of the Gr.2 winner Diamond Omi, while his sons RUBIANO and QUIET AMERICAN are respectively the broodmare sires of the Gr.2 winners Neko Bay and Quiet Giant. Rubiano mares have two Graded performers among their six foals by Giant’s Causeway.

Giant’s Causeway has also sired the Gr.2 winner Naissance Royal from a mare by FORTY NINER. Mares by Forty Niner’s son DISTORTED HUMOR look to have huge potential with Giant’s Causeway, all the more so because his first nine foals out of them include the Gr.1 winner Book Review and the Gr.2 winner Caroline Thomas.

Mares by THUNDER GULCH have 31 foals by Giant’s Causeway and they include five stakes winners (16%). TORRENTIAL, another son of GULCH, sired the dam of Giant’s Causeway’s classic winner Penelopa.

The SEATTLE SLEW line has provided some of Giant’s Causeway’s best recent results. For example his Man o’War Stakes winner Imagining and his Gr.2 winners Protonico and Chief Havoc are all out of A.P. INDY mares, with this nick having 9% black-type winners. SEATTLE SLEW is the broodmare sire of Giant’s Causeway’s tremendously talented son Eskendereya. This links to the impressive record Seattle Slew mares built with Storm Cat. Seattle Slew also sired the second dam of the Gr.1 winner Frost Giant.

Storm Cat had numerous good winners inbred to NORTHERN DANCER. Giant’s Causeway is therefore an option for daughters of DANZIG, DIXIELAND BAND, NIJINSKY, SADLER’S WELLS, DEPUTY MINISTER, etc. His matings with SADLER’S WELLS mares are bearing fruit, with 13% black-type winners, headed by the Gr.1 winner Eishin Apollon.

Giant’s Causeway’s matings with DANEHILL mares have yielded Gr.1 winners in Britain (Intense Focus) and Australia. He also has the Japanese Gr.3 winner A Shin G Line out of a DANZIG mare, plus the Gr.1 winner Dalkala and a Gr.2-placed horse from four foals out of ANABAA mares. He could suit daughters of WAR FRONT, HARD SPUN and EXCHANGE RATE (who is out of a SEEKING THE GOLD mare).

His high-class sons First Samurai and Await The Dawn have dams by DIXIELAND BAND, while another Gr.1 winner, Aragorn, has a NORTHERN DANCER mare as his second dam. Maids Causeway and Niagara Causeway are Graded winners inbred to Northern Dancer, with the second line coming via NUREYEV.

Giant’s Causeway has a South American Gr.1 winner inbred 2 x 3 to STORM CAT, with a dam by HENNESSY, and his Gr.3 winner Winning Cause has a second dam by STORM CAT.

DEPUTY MINISTER is the broodmare sire of Man of Iron, winner of the Breeders’ Cup Marathon, and his sons DEHERE, SILVER DEPUTY and FRENCH DEPUTY rank among the broodmare sires of Giant’s Causeway’s Graded winners. This suggests that AWESOME AGAIN mares would also suit, especially as they create 4 x 4 inbreeding to BLUSHING GROOM. Giant’s Causeway’s classic-winning son Footstepsinthesand and the Gr.1-winning Heatseeker are inbred 4 x 3 to BLUSHING GROOM.

Giant’s Causeway’s second dam Immense was a stakes-winning daughter of ROBERTO. He has Group/Graded winners out of daughters of KRIS S. and LEAR FAN which are therefore inbred to ROBERTO, including the Gr.1 winner Rite of Passage.

Storm Cat proved highly successful with mares by DAMASCUS and his sons PRIVATE ACCOUNT and TIME FOR A CHANGE. Giant’s Causeway has the Gr.2 winner Fairbanks out of a TIME FOR A CHANGE mare.
