TAKE Giant's Causeway to record his fourth consecutive Group One victory within nine weeks in the Juddmonte International Stakes at York tomorrow.

Aidan O'Brien's three-year-old started his winning run in the St James's Palace Stakes at Royal Ascot where he beat Valentino.

The son of Storm Cat followed that effort with another head-success, this time beating Kalanisi in the Coral-Eclipse Stakes at Sandown over tomorrow's trip of 10 furlongs.

At "Glorious" Goodwood three weeks ago the powerfully-built colt put up his best performance so far to beat a top-class field for the Champagne Lanson Sussex Stakes.

Always close up in a strongly-run contest, Giant's Causeway led a furlong out and kept on gamely to beat the French-trained Dansili by three-quarters of a length.

Giant's Causeway has been dubbed the "iron horse" for his tough constitution and never-say-die attitude and just 10 days after his latest triumph was said to be "kicking his box door down".

O'Brien has recently declared himself very happy with the horse.

Although tomorrow's £450,000 contest will be no pushover Giant's Causeway has outstanding credentials and is awarded the nap.

He will have most to fear from his old adversary Kalanisi, who has been relatively lightly raced and remains open to improvement.

Whatever the fate of Giant's Causeway, O'Brien's Ballydoyle team can win the opening race of the three-day Ebor meeting -- the Breckenbrough Racing Acomb Stakes -- with Hemingway.

The son of Spectrum was an impressive winner of a seven-runner maiden on his debut at Galway last month, stretching clear in the straight to score in great style by seven lengths from Avorado.

Last year's Acomb winner was King's Best, who went on to win the Sagitta 2000 Guineas, and a good performance by Hemingway on the Knavesmire could see him take a prominent position in the betting for the Newmarket Classic.

Michael Jarvis' improving colt Marienbard can stake his claims for the Rothmans Royals St Leger with victory in the Group Two Great Voltigeur Stakes.
