Tungsten Strike is a 20-1 chance with Coral for the Gold Cup at Royal Ascot after making virtually all the running to land the Woodcote Stud Sagaro Stakes at the Berkshire track.
Amanda Perrett's six-year-old finished eighth behind Yeats in the premier staying contest last summer, but his trainer is confident of a better run with another year on his back.
The 9-2 shot was soon in the lead under Darryll Holland and galloped on to hold Baddam by a length and a half.
St Leger runner-up The Last Drop, sent off the 11-8 favourite, finished a further three and a half lengths away in third.
Perrett said: "He is now a year older and stronger and he might get the trip in the Gold Cup.
"Last year he did not quite get home and, while he does not have the class of Yeats, he is honest and he gallops.
"The Gold Cup is the major aim and he will probably go to Sandown for the Henry II in between."
The rest of the day belonged to Jamie Spencer, who registered a 28-1 treble, highlighted by Royal Hunt Cup winner Cesare proving different class in the Listed Britain's Got Talent Paradise Stakes.
Having his first start for 229 days, the 2-1 favourite was toying with his rivals from halfway and sluiced through the pack to cruise clear inside the final furlong and win on the bridle.
Trainer James Fanshawe said: "He looked better than ever and was always travelling.
"I did not enter him for the Queen Anne last week and I rather regret that, but there are plenty of nice races for him."
Spencer had been on the mark in the previous race as Italian Girl set herself up for what could be a profitable summer with a facile victory in the X Factor Swinley Conditions Stakes.
The Michael Tabor-owned three-year-old scampered clear in stylish fashion when pulled out for a run inside the final two furlongs and she went away to collect by three lengths.
Winning trainer Alan Jarvis said of the 9-4 favourite: "She has still to come in her coat and has a lot of filling out to do, so we will take our time with her."
Spencer's final success came as Michael Bell's Hoh Mike (2-1 joint-favourite) justified strong market support in the waterhomes.com Pavilion Stakes to collect by half a length.
Bell said: "We will go quietly with him this year and avoid the big races like the Golden Jubilee and King's Stand.
"He can go and take on the big sprinters as a four-year-old, but this year we will just have a lot of fun with him and tread quietly."
Jamie Osborne's two-year-olds have made a blinding start to the season and Mount Pleasure continued the good run in the waterhomes.com Garter Conditions Stakes.
The Jimmy Fortune-ridden 6-1 shot ground out success down the centre of the course and stayed on to account for Littlemisssunshine by a neck.
