Fillies by Coolmore sires Hennessy and Rock Of Gibraltar fought out a controversial finish to the English 1000 Guineas at Newmarket on Sunday.

Special Duty (3f Hennessy – Quest To Peak by Distant View) won on protest to give Juddmonte Farms owner Khalid Abdullah his seventh English classic.  The filly’s dam is a full-sister to G1 winner Sightseek and a half-sister to another G1 winner in Tates Creek (Rahy).

Special Duty won the G2 Prix Robert Papin at Maison-Laffitte in July 2009 and added the G1 Cheveley Park Stakes at Newmarket in October.  Her sire Hennessy succumbed to a heart attack in Argentina in 2007 while on shuttle duties from Coolmore.

Jacqueline Quest (Rock Of Gibraltar) passed the post a nose in front but Newmarket officials ruled she was at fault for a bumping duel inside the final furlong.  

Had Jacqueline Duty kept the race, it would have been a classic first for Rock Of Gibraltar in England.  He shuttles to Coolmore Australia and will stand the 2010 season at a $33,000 fee.

Rock Of Gibraltar has another talented filly in South Africa named Gibraltar Blue.  The Mike de Kock trained filly was a brilliant winner of the G2 KRA Fillies Guineas at Greyville on Sunday night.

Gibraltar Blue (Ire) was sent off an odds-on favourite and never looked back after Anton Marcus set her alight from the stalls.  She maintained a strong gallop throughout and clocked 1.34.19s for the mile.

Gibraltar Blue (3f Rock Of Gibraltar – Holly Blue by Bluebird) started her career in Ireland and won a Fairyhouse maiden in August last year before finishing fourth to Music Show in the G2 Rockfel Stakes at Newmarket in October.

She was exported to South Africa earlier this year and races for Klawervlei Stud owner John Koster.
