Workforce, the Epsom Derby and Prix de l’Arc De Triomphe winner, is returning from stud bduty in Japan to stand as a dual-purpose sire at Knockhouse Stud in Ireland in 2017.

By the 2000 Guineas winner King’s Best out of the Sadler’s Wells mare Soviet Moon, the nine-year-old has been purchased from a Japan-based syndicate who will retain shares in the stallion.

Workforce raced only nine times for Sir Michael Stoute with his highloights being his Derby win by seven lengths and his Arc victory as a three-year-old.

Workforce raced four times as a 4YO with his best efforts being seconds in the G1 Eclipse Stakes and G1 King George VI and Queen Elizabeth Stakes.

Sean Kinsella, owner of Knockhouse Stud, said: "He will be the first Derby or Arc winner to stand at Knockhouse Stud. He will put a lot of class into his runners.

“He was well-supported in Japan and has big crops on the ground there."

Workforce will join Notnowcato, Libertarian, September Storm and Prince Forli at the County Kilkenny stud.
