Johannesburg heads July field Last year`s champion two-year-old Johannesburg heads 13 entries from Aidan O`Brien`s stable for the #220,000 Darley July Cup at Newmarket.After finishing eighth in the Kentucky Derby, Johannesburg, is expected to target Europe`s top sprints in a bid to add to his four Group One successes last season.O`Brien, who has won this Group One contest over six-furlongs twice with Stravinsky (1999) and the ill-fated Mozart (2001), has his 2000 Guineas winners Rock Of Gibraltar (English) and Landseer (French) among his other entries.Hawk Wing, the unlucky runner-up to Rock Of Gibraltar at Newmarket, has also been put in by the Ballydoyle trainer.Saeed bin Suroor has six entries for Sheikh Mohammed`s Godolphin operation, including the fourth horse home in the race last year, Three Points, and the well-regarded three-year-olds Meshaheer and Waldenburg.Sheikh Mohammed has won the race twice in the past with crack sprinters Ajdal (1987) and Soviet Star (1988).A host of established British-trained sprinters and potentially top-class speed merchants feature amongst the 57 entries.The older horses include Sir Michael Stoute`s Misraah, third in last year`s race, Danehurst from Sir Mark Prescott`s yard and Richard Hannon`s fast improving Reel Buddy.
