Sewickley, dual grade I-winning stallion, died July 10, in Maryland. He was 28. According to his owner, the cause of death was complications due to colic.

Bred in New Jersey by Robert S. Evans, Sewickley was by Star de Naskra, 1979 champion U.S. sprinter. His dam, Surgery, by the legendary Dr. Fager, was named New Jersey's 1989 Broodmare of the Year and also produced grade I winner Shared Interest.

Among Sewickley's 11 wins are scores in consecutive runnings of the Vosburgh Stakes (gr. I) (1989 and 1990), the Fall Highweight Handicap (gr. II), the Tom Fool Stakes (gr. II) (all at Belmont Park); and the Commonwealth Breeders' Cup Handicap at Keeneland. In 16 graded stakes attempts, he finished in the money 12 times.

A homebred runner for Evans, the Flint S. Schulhofer trainee achieved champion status in New Jersey five times in two years as champion sprinter and older horse in 1989; and champion sprinter, older horse, and Horse of the Year for 1990. Upon his retirement at the end of his 5-year-old campaign, Sewickely's record stood at 11-9-4 from 32 starts with earnings totaling $1,017,517.

Sewickley entered stud for the 1991 breeding season at Courtland Farm in Maryland. He was moved to O'Sullivan Farms in West Virginia in 2000 after being named among the top sires in the state for 1999.

Pensioned about 12 years ago, he is the sire of 57 winners from 71 starters, including stakes winners Normandy Beach, Show and Tell, and Perfect Challenge as well as Javeriano, a group II winner in Panama.
