Spanish Moon landed a Group One victory when staying on gamely for Ryan Moore to take the Grand Prix de Saint-Cloud.Sir Michael Stoute's charge (8-1) is serving a suspension from British racecourses after failing to go into the stalls at Newmarket in May, but was more compliant this time.Travelling nicely in behind the early leaders, Moore unleashed his mount with a strong run inside the final two furlongs to beat Alpine Rose, with the odds-on Youmzain in third after failing to pick up at a crucial stage.Stoute said: "I want to thank the French starters for helping him into the stalls. The horse is entered in the Arc and we shall discuss that option."Mick Channon was understandably disappointed with Youmzain's display and said: "I've no excuses to make."His jockey, Christophe Soumillon, added: "I followed the eventual winner, but in the final straight he was incapable of regaining ground and actually even weakened in the last few metres."Maybe he hasn't recovered from his run in the Coronation Cup at Epsom."
