Adena Springs resident and leading sire El Prado (Ire) (Sadler's Wells--Lady Capulet, by Sir Ivor) died of a heart attack soon after being turned out into his paddock Monday morning. Still active at 20, the stallion stood for $75,000 in 2009.

The Group 1 winner was bred in Ireland by Lyonstown Stud, was campaigned by Robert Sangster and legendary trainer Vincent O'Brien. Out of 1977 Irish 1000 Guineas winner Lady Capulet, the gray is a half brother to 1987 Irish champion three-year-old Entitled (Ire) (Mill Reef). As a two-year-old, El Prado won four of six starts, including the G1 National S., G2 Beresford S. and G3 Railway S., and was named Ireland's champion juvenile of 1991.

Off the board in three starts in 1992, El Prado was retired to Brereton Jones's Airdrie Stud in Midway, Kentucky in 1993, standing for the partnership of Sangster, O'Brien, Coolmore and Frank Stronach.

Meanwhile, Classic winner and successful sire Summer Squall was euthanized Tuesday, Sept. 22, at William S. Farish’s Lane’s End Farm near Versailles, Ky., because of complications from the infirmities of old age.

“He was an important part of one of Lane’s End’s great families,” Farish said about the half-brother to two-time leading sire and current Lane’s End stallion A.P. Indy .

A 22-year-old son of Storm Bird, Summer Squall was produced from 1992 Broodmare of the Year Weekend Surprise (by Secretariat). Summer Squall stood at Lane’s End his entire career before being pensioned because of fertility issues in 2004.

Summer Squall is represented by 37 stakes winners, including 1999 Horse of the Year and champion 3-year-old male Charismatic, who won that year’s Kentucky Derby (gr. I) and Preakness Stakes (gr. I) and ran third in the Belmont Stakes (gr. I).

Summer Squall, a Preakness winner himself, also is represented by 1996 champion 2-year-old filly and Breeders’ Cup Juvenile Fillies (gr. I) winner Storm Song, plus additional grade I winners Summer Colony and Summerly. The last-named won the 2005 Kentucky Oaks (gr. I). - TDN and Bloodhorse
