Diamond Carl, trained by Francois Nicolle, won the Grand Steeple-Chase de Paris at Auteuil as a surprise winner at 11/1 odds.
The seven-year-old Diamond Carl triumphed on heavy ground, finishing six lengths ahead of the competition in the three-mile, five-furlong race.
Last year's winner, Gran Diose, finished fifth in the 10-runner contest despite starting as a 13/8 favourite.
English jockey James Reveley secured second place riding Kolokico (8/1), with Grandeur Nature (12/1) and Toscana Du Berlais (40/1) finishing third and fourth respectively.
