Trippi, whose five graded stakes wins included a score in last year's Vosburgh Stakes (gr. I) at Belmont Park, has been retired from racing and will enter stud at Tom Simon's Vinery near Lexington. The 4-year-old son of End Sweep arrived at the farm Aug. 30.Vinery purchased a 25% interest in Trippi's breeding rights last August from Dogwood Stable, whose president, Cot Campbell, had bought the colt for $65,000 at the 1999 Keeneland April sale of 2-year-olds in training. Trippi raced his entire career for Dogwood and won seven of 14 races and earned $666,220.In addition to winning the Vosburgh, Trippi captured last year's Riva Ridge (gr. II), Flamingo (gr. III), and Swale (gr. III) Stakes and the Tom Fool Handicap (gr. II). He began this season with a runner-up effort in the Gulfstream Park Breeders' Cup Sprint Handicap (gr. II). He injured a heel during the running and was able to start only three more times. Following what turned out to be his final start, a close third-place finish in a Saratoga allowance event on Aug. 11, Trippi was sent to Rood and Riddle Equine Hospital near Lexington for a thorough foot examination.Trippi, who was produced from the Valid Appeal mare Jealous Appeal, is a half-brother to grade II winner Appealing Skier, to multiple stakes winner Miss Jealski, and to 2001 juvenile stakes winner Jealous Forum. Details of Trippi's syndication and his fee will be announced in September.
