The John Gosden-trained Derby hope Plea Bargain failed by a neck to peg back Vatori in the Prix Greffulhe at Saint-Cloud yesterday.
Temperature set the early pace in the Group Two contest over a mile and a quarter but was weakening when he broke his leg and fell over a furlong out.
Vatori, meanwhile, had put down a challenge on the outside to take the lead and in a good finish held on well when pressed by Jimmy Fortune on Plea Bargain. The 7-1 winner will now be aimed at the Prix du Jockey-Club at Chantilly next month.
In the German 2,000 Guineas in Cologne Johnny Jumpup finished an honourable second to Santiago Ralph Beckett's colt was always prominent under Jamie Spencer but had no answer to the winner's finishing kick and was six lengths adrift at the line.
For his effort in the Group Two contest, Johnny Jumpup picked up £38,000 in prize-money. Mick Channon's Capable Guest was outpaced in the early stages and came home in seventh.
The Kiddykid is on course to attempt to win the Greenlands Stakes at the Curragh on Saturday for the second successive year. Last week the five-year-old gelding gave his trainer, David Evans, his biggest success when lifting the Group Two Duke of York Stakes.
