Genuine Risk, one of only three fillies to win the Kentucky Derby, died yesterday at Newstead Farm in Upperville, Va.

The 1980 Derby winner died peacefully about 7:30 a.m. at the age of 31 after eating a hearty breakfast and being turned out in her paddock, said Cindy Perry, an office administrator at the farm. Perry said the filly had not been ill.

Genuine Risk was the oldest living Derby winner, and the only filly to finish in the top three in each of the Triple Crown races. Ridden by Jacinto Vasquez in all three, she was second to Codex in a controversial Preakness, and then ran second to the Belmont Stakes.

"Genuine Risk was an amazing horse with tremendous heart that lived a life befitting a champion," owners Bertram and Diane Firestone said in a statement issued by the farm. "We are truly blessed that she was a part of our life and we are deeply saddened by her passing."

It was in the 1980 Derby that Genuine Risk made history, taking a commanding lead in the stretch of the 106th Derby and outrunning Rumbo and Jaklin Klugman for the victory. She paid $26.80 to win and immediately became one of the top fillies in racing history.

A whirlwind of a month is almost over for Danny Lee.

First, he became only the sixth player in the 106-year history of the Western Amateur to sweep medalist and match play honors, joining a group that includes Phil Mickelson and Curtis Strange.

Then came a tie for 20th over the weekend in his PGA Tour debut at the Wyndham Championship. Those performances leave the 18-year-old from New Zealand as one of the favorites in the U.S. Amateur at Pinehurst, where he opened with a 1-over 71 in the opening round of stroke play.

Qualifying for the 312-player field is split between Pinehurst's No. 2 and No. 4.
