Triple Aspect maintained his formidable record at Sandown in the Coral Charge today.
William Haggas' colt was a slightly unlucky second in the Group Three last year but had already struck before on the Esher track's sprint course.
The 15-8 favourite was right at the back of the field and conceded first run on Group Therapy, but really caught alight under Liam Jones in the final furlong to run out an impressive winner.
Haggas' wife Maureen said: "He has had a lot of problems, but the treadmill has been the making of him and he loves it.
"Liam gets on really well with him and they came back on the bridle quickly today. If they had been off it a bit longer he would have won easier."
Trainer Clive Cox managed to saddle the first and third in the Coral Challenge.
For much of the way it looked as if Philip Robinson and the Cox-trained Dunn'o were going to dictate the pace throughout but sharks began to gather with a couple of furlongs to run.
While eventual runner-up Acrostic tried to sneak up the inside rail it was left to the lightly-raced Black Spirit and Luke Morris to come up with the decisive late charge, scoring by half a length.
The 33-1 shot is very lightly-raced and one of only a couple of three-year-olds in the field.
Speaking from Haydock, Cox said: "I'm very pleased. I thought Dunn'o had it for a minute so I was cheering him home but Luke got a very good tune out of Black Spirit and I'm thrilled for everyone."
Winning owner Alan Spence added: "He'd had a breathing problem so we gave him the same treatment as Eradicate, who came out and won the Swinton Hurdle.
"He'll get further and improve again."
Seb Sanders made every post a winning one on Virginia Hall in the Coral Distaff.
Sir Mark Prescott's filly had proved no match for Seta on her seasonal reappearance at Warwick but looked a different proposition here.
The 11-2 chance had shown smart form in France last season though and got first run on her rivals two furlongs out and never looked like being caught.
Fontley ran on from the rear to pip Lady Darshaan for second but she was still some three lengths down at the line.
"She was a bit fresh at Warwick but she has really stepped up from that here - she did that very well," said Sanders.
"A Group Three would be the obvious step and I'm sure Sir Mark will have a plan."
King Of Wands (8-1) broke the course record when holding off the late lunge of Illustrious Blue in the Coral Marathon.
Behind both Manighar and Opinion Poll on his last start at Goodwood, he showed that running to be all wrong.
Manighar was sent off the odds-on favourite to confirm the placings but was very disappointing, while Opinion Poll ran on for third.
It was left to the veteran Illustrious Blue to throw down the last challenge as he made up plenty of ground from the rear and despite John Gosden's winner drifting into the rail close home, William Buick's mount was never in danger of losing the race.
Owner Robin Geffen said: "We love the jumps and he was bought to go hurdling so we'll have to see what happens.
"We want all our horses to be dual-purpose really.
"This guy is all heart, he's really stepped up, and that was a great performance off level weights."
