Sole Power landed back-to-back runnings of the Pearl Bloodstock Palace House Stakes following a commanding performance at Newmarket.
The 9/4 favourite benefitted from a vintage Ryan Moore ride, the pair pouncing in the final furlong to collar the field in the final strides to record a half-length victory.
The veteran Kingsgate Native was second with Hot Streak continuing his improvement in third.
"Ryan said he was super today - unlike his trainer, he is improving with age," said trainer Edward Lynam.
"He's very honest - too honest - and Ryan loved him today. We're looking forward to another good season. If he gets three things - his ground, that he's bouncing out of his skin, and that Ryan Moore rides - he'll go to the Temple Stakes.
"If not, then he's off to the King's Stand at Royal Ascot."
Kingsgave Native's effort delighted his trainer Robert Cowell, who said: "He's nine years old and showing no signs of stopping. He looked a bit burly today but the plan was to have him ready to defend his title in the Temple Stakes. I don't think he'll be going to Royal Ascot anyway."
Sky Bet were suitably impressed and have cut Sole Power to 7/1 (from 12/1) for the King's Stand Stakes at Royal Ascot, a race the seven-year-old won last year.
"Sole Power produced another authoritative performance at Newmarket and could take all the beating if getting his favoured fast ground at Royal Ascot," said Sky Bet spokesman Michael Shinners.
