Paddington made it a brilliant six from six for the season with a dominant front-running victory in the Qatar Sussex Stakes at Goodwood.
The Siyouni colt has not looked back since making a successful start to his campaign in a handicap at Leopardstown, winning a Listed race at the Curragh, the Irish 2,000 Guineas and the St James's Palace Stakes before successfully stepping up to 10 furlongs in the Coral-Eclipse.
Dropping back to a mile, Aidan O'Brien's teak-tough three-year-old was the 4/9 favourite to make light of testing conditions and controlled matters from flag-fall in the hands of Ryan Moore.

Three-time Group One-winning filly Inspiral was the first of his challengers to throw down a challenge, but her effort was short lived and in the end it was French raider Facteur Cheval who emerged as the biggest threat.
But try as he might, he could never quite get on terms with Paddington, who had matters well in control as he passed the post with a length and a half in hand.
The winner was emulating former Ballydoyle great Giant's Causeway by completing the St James' Palace, Coral-Eclipse, Sussex Stakes treble.
The 'Iron Horse', as he was affectionately known, went on to add the Juddmonte International at York to his CV 23 years ago.
O'Brien said: He's a very special horse. We were worried about the ground - even though he'd won on it, it wasn't in this class of race and Ryan rode him for speed. He was over the moon with him and we're so lucky to have him. I'm so delighted for the lads, he's a very special horse.
"We'll do whatever the lads want to do. He's much quicker than Giant's Causeway was, he's tactically quick, but he can quicken as well. 'The Giant' was tactically quick, but he was a grinder after that.
"This horse can really turn it on when you have to, he's very unique. It will depend on what the lads want to do and we'll talk to them after a week."
Paddington's next stop is almost certain to be the Knavesmire on August 23.
O'Brien added: "He's unique. It will depend on what the lads want to do and we'll talk to them after a week, but he's got a lot of options. He could go to York, he could do anything. But he's very special, we think.
"With every race, he's getting heavier, which is very unusual, and he's getting calm, but he's getting quick. He's really trying. He's three or four kilos heavier today than he was the last day.
"It is special that we have Peter (Brant) and Stephanie (Seymour) today that we didn't have before with him. He's very exciting. We love these big days and I'm delighted that the lads are happy to run on them."
Big Evs makes it count in Molecomb
Big Evs proved his surprise Royal Ascot success was no fluke with victory in the Jaeger-Lecoultre Molecomb Stakes.
Narrowly beaten on his debut at Redcar in May, Mick Appleby's juvenile was sent off at 20/1 for the Windsor Castle Stakes but ran out a clear-cut winner.
He was the 9/4 joint-favourite to follow up at Group Three level and a smart start meant he was soon leading the field in the hands of Jason Hart.
Purosangue came at him hard as the post loomed, but Big Evs kept responding to pressure and clung on by a neck.
Kylian, the other 9/4 favourite, appeared outpaced early on, but made late progress to place third and may well have finished closer with a clearer run.
Betfair cut Big Evs to 5/1 from 8/1 for the Gimcrack at York on August 25, although connections also raised the possibility of paying the £40,000 required to supplement him for the Nunthorpe on the same day.
He is an 8/1 shot with Paddy Paddy Power to become the first two-year-old to win the all-aged Group One since Kingsgate Native in 2007.
Magical Sunset shines in Oak Tree victory
Magical Sunset finished with some gusto to secure the Whispering Angel Oak Tree Stakes.
Richard Hannon's filly won three times last season, including a Listed success, but could finish only fifth when favourite to make a winning reappearance in the Fred Darling Stakes at Newbury in April.
She had also troubled to fail the judge in four starts since, but bounced right back to the best in deteriorating conditions on the Sussex Downs.
Matilda Picotte cut out much of the running in the seven-furlong Group Three before being swallowed up by the chasing pack, and in the final furlong 4/1 joint-favourite Breege hit the front.
But Kevin Stott was biding his time in behind aboard 18/1 shot Magical Sunset and she picked up well once in the clear to get up and score by three-quarters of length.
Balding bags day two double
Andrew Balding's The Goat routed the opposition in the curtain-raising Coral Handicap to spark a double for the Kingsclere handler.
Despite being placed in three of his four previous races, the Cracksman colt was a 25/1 chance stepping up to a mile and a half in the hands of Jason Watson and clearly relished the testing conditions.
Amleto, the 5/2 favourite, did his best to bridge the gap inside the final furlong but The Goat was away and gone and passed the post with 12 lengths in hand.
Balding completed his brace when Flora Of Bermuda (5/1) made a mockery of her poor draw to land the British EBF 40th Anniversary Alice Keppel Fillies' Conditions Stakes under Oisin Murphy in similarly emphatic style.
Having tracked across towards the stands rail early, the Andrew Balding-trained daughter of Dark Angel powered home in the five-furlong contest and had the race won at the furlong pole.
Having been unlucky when runner-up in the Hilary Needler at Beverley and again when first of the far-side group when drawn on the wrong side in the Queen Mary at Royal Ascot, she gained just compensation, surging clear of Juniper Berries to score by four lengths, with a further three lengths back to Indispensable.
Proven mudlark There's The Door (6/1), dropping back in trip, outstayed her rivals in the 10-furlong British European Breeders Fund EBF Fillies' Handicap.
In a race where David Egan was unshipped by Decoration coming out of the stalls, the David Evans-trained three-year-old tracked Chips And Rice and took it up from the dogged La Isla Mujeres inside the final furlong, having enough to hold the staying-on Persist by half a length.
Murphy completed his own double when Rhoscolyn (2/1 favourite) defeated Wobwobwob by a lengths as the pair drew clear of the remainder in the concluding seven-furlong World Pool Handicap.
The David O'Meara-trained five-year-old had been steadily dropping down the weights and the heavy ground played to his strengths, with Murphy's mount grinding down the gutsy Wobwobwob to gain a fifth career victory.
