The Pennsylvania couple paid $950,000 on the second day of the Keeneland September Yearling Sale for a dark bay or brown filly sired by the late 1977 Triple Crown winner. The price, Roy Jackson said, probably was higher than usual because of the circumstances.

Because of health problems, Seattle Slew sired only four horses - all fillies - in 2002 before his death in May of that year. Those four horses are now yearlings, and three of them are in Keeneland's sales catalog. Two were sold Tuesday, with one scheduled to be sold Wednesday.

The Jacksons bought the first of the three to pass through the sales ring. Eaton Sales consigned the filly, which was out of Pleasant Temper, by Storm Cat.

"He's dead, and we've always wanted a Seattle Slew, a filly in particular," Gretchen Jackson said. "The fact that this was one of the last to be in the marketplace really encouraged us to go after her."

The other Slew-sired filly sold Tuesday, named Ski Seattle, brought $800,000 from B. Wayne Hughes. Ski Seattle, a dark bay or brown filly out of Ski Dancer, was consigned by Lane's End Farm of Versailles.

"Is it bittersweet? Yes and no," said Bill Farish, of Lane's End. "This is a real nice filly. The thing about Seattle Slew is he is recognized as one of the best broodmare sires and to have a filly by him in his last group is pretty special."

Eighteen horses sold for $1 million or more on Tuesday, raising the two-day total to 26. It was the second-highest total of million-dollar horses sold in a single day in the September sale's history. Nineteen were sold on one day in 2000.

Tuesday's sale featured the highest-priced yearling sold since 1985. Japanese trainer Hideyuki Mori paid $8 million - the fourth-highest price ever for a yearling - for a Storm Cat colt out of Welcome Surprise.

The average price for the 179 horses sold on the sale's second day was $488,620. The median was $260,000.

Through two days, the average price is $431,656 and the median is $260,000.

All those numbers are improvements from last year, when Keeneland set numerous September sales records.

"We do believe that this is the place where people come to spend money," said Geoffrey Russell, Keeneland's director of sales. "It's global. This is where they all come to buy."

Irish veterinarian Demi O'Byrne, the buyer for Coolmore Stud, and John Ferguson, the agent for Sheik Mohammed bin Rashid al Maktoum, the crown prince of Dubai, continued their buying sprees Tuesday.

O'Byrne bought eight horses, four for $1.3 million or more, and was the immediate underbidder for the $8 million colt. He paid $2 million for a bay colt by now-pensioned sire Danzig, out of Scads, that was consigned by Claiborne Farm and $1.9 million for a bay colt by Galileo, out of Regina Maria.

O'Byrne also paid $1.3 million for a bay Grand Slam colt, out of Sheza Honey.

Ferguson, who bought 19 horses on Monday, continued his spending spree Tuesday with 21 purchases - four for $1 million for more. Ferguson paid $3.1 million for a Kingmambo bay colt, out of Zuri; and $1.4 million for another Danzig colt, out of Shouldn't Say Never.

Seattle Slew sired his share of million-dollar horses, and some of his progeny - most notably A.P. Indy - also have gone on to become top sires. Seattle Slew also sired many top broodmares, and his impact on the breed will be felt for years, said Reiley McDonald, the co-owner of Eaton Sales.

"He was a medium-sized, plain brown yearling when he came through," McDonald said. "He was built in such a way that he had great efficiency of motion. But mostly, he had this great, huge heart, what we call the will to win. That is what he has thrown off to most of his progeny.

"There isn't anybody in our business who doesn't get nostalgic when they think of Seattle Slew and all he did for our business."

Russell said Seattle Slew belongs on the list of top sires of recent years, a short list that also would include Northern Dancer, Mr. Prospector and Storm Cat.

"He was the lightning in a bottle," Russell said. "He will be sadly missed. He was a wonderful racehorse who parlayed it into being a wonderful stallion."
