Postponed continued his winning run with a stunning display in the Queen Elizabeth II Coronation Cup at Epsom.
Despite winning the King George VI And Queen Elizabeth Stakes at Ascot and the Prix Foy at Longchamp last season for Luca Cumani, the five-year-old was moved across Newmarket to join Roger Varian ahead of the new campaign.
He made a flying start for his new trainer at Meydan, winning the Dubai City of Gold and the Dubai Sheema Classic, and was the 8-11 favourite to make a successful return to British action.
With stable companion Roseburg deployed as a pacemaker, Postponed was settled in third place for much of the mile-and-a-half journey by Andrea Atzeni.
Roseburg committed for home rounding Tattenham Corner, but Postponed was moving sweetly in behind and picked up in style once given his head to seal a four-and-a-half-length success.
Aidan O'Brien's top-class filly Found kept on for pressure to fill the runner-up spot, with Roseburg holding on to third.
Atzeni said: "He's just a proper racehorse. You can put him anywhere in a race.
"He travels well, goes on any ground and quickens up.
"We're very lucky. He travels for fun and he quickens."
The brilliant Postponed leaves his rivals trailing in the Queen Elizabeth II Coronation Cup.

Winning owner Sheikh Mohammed Obaid said: "I'm really proud of this horse and since he joined Roger, I think he has improved.
"Whatever people say, all the credit goes to Roger and his staff.
"If he's sound, he'll go back next year for the Sheema Classic."
Postponed is now likely to defend his crown in the King George on 23 July.
Varian said: "Jack (Mitchell) did a super job (on Roseburg) as he just kept an even pace.
"Postponed is a remarkably versatile horse - he handles different grounds, different pace and different tracks.
"He's a very balanced horse and he's really the ultimate athlete.
"The timing always felt right to come here and then go straight to the King George."
Found could make a swift return to action in the Prince of Wales's Stakes at Royal Ascot.
O'Brien said: "She ran very well and we're very happy with the run.
"It was a very slowly-run race and obviously she likes a nicely-run race as that's when she's always at her best, but Ryan (Moore) was very happy with her.
"She'd have no problem with faster ground. I think she could go to Royal Ascot, it's very possible, and I'd say if she does it will be the Prince of Wales."
St Leger heroine Simple Verse was doing her best work at the finish, passing the post in fourth place.
Connections felt the lack of pace was detrimental to her chances.
Trainer Ralph Beckett said: "I think they only raced for seven furlongs and that was never going to suit her. That really sums it up in a nutshell.
"We'll see how she comes out of it and we're not ruling anything out."
