Pinatubo maintained his unbeaten record with a scintillating display at Goodwood in the Vintage Stakes.
Charlie Appleby's charge has progressed from winning a minor event at Wolverhampton to landing the Woodcote Stakes at Epsom and the Chesham Stakes at Royal Ascot, with his most recent triumph seeing him rocket to favouritism for next year's 2000 Guineas.
This Group Two test appeared far from straightforward on paper, with Aidan O'Brien's Chesham runner-up Lope Y Fernandez, Richard Hannon's Superlative winner Mystery Power and Mark Johnston's grey Visinari among six rivals - but he put them to the sword in the style of a colt destined for the top.
Visinari set out to make all the running under Frankie Dettori, but Pinatubo ranged alongside halfway up the home straight.
Ridden by James Doyle, the Shamardal colt swiftly engaged overdrive, leaving his rivals trailing in his wake as he powered to the line to score in hugely impressive style by five lengths.
Appleby said: "I'm thrilled with this horse - he is a true professional. He jumped and travelled well. James got him into a lovely rhythm and once he turned into the straight I couldn't see much coming from behind.
"You rewind back to Wolverhampton, he was a bit slow away and green and he picked up well. From there that is all we have ever seen.
"You don't notice this horse at home, which is great. It is full credit to the team back home that look after him. If you looked at him walk around the paddock he is like an old stayer. He just gets on with his job and thankfully he is very good at it."
Pinatubo looks set to test the water at Group One level for the first time in the National Stakes at the Curragh on September 15.
"You really can't get excited about watching him in the morning, but there is no doubt what he does in the afternoon excites you," Appleby said.
Looking forward he added: "We have spoken about it before coming here and we might have been a bit bold, but we felt the National Stakes might be the likely target.
"I see no reason on the back of that why that won't be his next target."
