Aidan O'Brien has mapped out a three-race plan for his unbeaten juvenile River Tiber. The Wootton Bassett colt looked something out the ordinary when scoring by 10 lengths on his racecourse debut at Navan in April and doubled up at Naas the following month. Having completed his hat-trick in the Coventry Stakes at Royal Ascot, River Tiber heads ante-post lists for next year's Qipco 2000 Guineas and looks set to step up in trip before the season is out.
