Top Japanese racehorse Manhattan Cafe, who struggled to a 13th-place finish in Sunday's Prix de l'Arc de Triomphe, will retire due to an infection in his left leg, trainer Futoshi Kojima said Monday.

Kojima told reporters that the 4-year-old horse is thought to have tendinitis, which in some cases can be fatal in racehorses, and that the prestigious race at Longchamp "would be his last race."

In April, Manhattan Cafe became the first horse in 17 years to win the spring Tenno-sho race after taking the Kikka-sho and Arima Kinen titles the previous year as a 3-year-old. He is to move to Chitose, Hokkaido, to start stud duty.
