Old Persian could step up into Group Two company for the King Edward VII Stakes at Royal Ascot after a game success at Newmarket.
The Godolphin-owned son of Dubawi showed a willing attitude to beat two rivals and register a third course victory in the Betway Fairway Stakes.
The Charlie Appleby-trained colt was sent off 1-2 favourite, but was pushed all the way to beat Court House, the outsider of three.
Old Persian and Department Of War went head to head from the start of the 10-furlong contest, until the latter started to fade from a quarter of a mile out.
Court House then put in his bid and William Buick had to bustle up Old Persian to get on top close home and score by half a length.
“He was entitled to go off favourite and I thought he was the one to beat,” said Appleby.
“Going forward I think stepping him up in trip will see further improvement.
“We’ll take a look at something like the King Edward VII at Royal Ascot and probably head there. I know he’s going up in grade, but the step up in trip is going to suit him.
“He’s got a good head on him. He tries and he wants it. It makes things a lot easier.”
Purser battled on well to lift the Betway Charles II Stakes and follow up a victory at last month’s Craven meeting.
Rab Havlin had the John Gosden-trained colt on the front end from the outset, in what was a steadily-run race.
Purser first had to see of Aurum and was then challenged late on by Mutaaqeb, but the 6-4 favourite would not be denied and got home by a neck.
Purser was given a quote of 12-1 for the Jersey Stakes at the Royal meeting with Paddy Power.
