Grade I winner City Zip, who made his farewell race in the Breeders' Cup Mile (gr. IT) for the partnership of Charles Thompson, Carl Bowling, and Lakland Farm, has been retired from racing and will enter stud at Gus Schoenborn Jr.'s Contemporary Stallions near Coxsackie, N.Y. Contemporary Stallions purchased an 81% interest in City Zip from the partnership, and plans call for the 3-year-old son of Carson City to be syndicated and arrive at the farm in mid-November.City Zip swept Saratoga's three graded stakes for 2-year-old males last year, taking the Hopeful Stakes (gr. I) in a deadheat and winning the Sanford (gr. II) and Saratoga Special (gr. II) Stakes in outright fashion. This year at the Spa, he captured the Amsterdam Stakes (gr. II)."City Zip made history in New York, so it is fitting that he should retire here," Schoenborn said. "City Zip is the most accomplished 2-year-old ever to retire to stand in New York, and one of the best runners ever to retire to the state."City Zip, who ran unplaced in the Mile, retires with nine wins and nine placings from 23 starts and earnings of $818,225. Bred by Frank Stronach's Adena Springs and produced from the stakes-winning Relaunch mare Baby Zip, City Zip captured a total of eight stakes and placed in eight others.
