Rumstar provided his trainer Jonathan Portman with a third winner from as many runners in the Newmarket Academy Godolphin Beacon Project Cornwallis Stakes at Newmarket.

The Upper Lambourn handler claimed the Group 3 prize twice in three years with Royal Razalma (2014) and Mrs Danvers (2016), and Rumstar was an 8/1 shot to add his name to the roll of honour.
