Graded-stakes winner Williamstown has died. The 25-year-old son of Seattle Slew was euthanized Feb. 25 due to complications caused by the neurologic disease equine protozoal myeloencephalitis (or EPM).

Williamstown had been pensioned at Old Friends, the Thoroughbred Retirement Farm in Georgetown, Kentucky, since 2007. Michael Blowen, founder and president of Old Friends, made the announcement of his passing this morning (Feb. 26).

As a racehorse, Williamstown (Seattle Slew – Winter Sparkle, Northjet) scored his biggest win in the 1993 Withers Stakes at Belmont Park in track-record time of 1:32.79 for owner Peter W. Willmott. It was considered one of the fastest miles in racing history.

Williamstown’s three-year career included wins in other stakes, and seconds in the Jerome Handicap and King’s Bishop, among others. In all, Williamstown won five of his 24 starts and earned $360,884. He was also successful as a stallion, siring 15 stakes winners, including graded winner Vinemeister. 

Williamstown was pensioned from stud duty in 2007 after proving infertile. The Central Kentucky insurance firm Aubrey Insurance took possession of the horse and tried to place him in an equine program at University of Minnesota, but he did not fit their needs. Plans to euthanize Williamstown were underway when an employee at Aubrey decided to contact Blowen at Old Friends.

"I’ll never forget the day, nearly eight years ago, when a woman named Lisa called from Frank Aubrey Insurance and asked us if we had room for a horse named Williamstown," recalled Blowen. "I was thrilled. I had visited Williamstown years ear
