Input: Question: Who was the jockey for Recitation in the July Stakes at Newmarket Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.
