Gusto won his fifth race in a row in the bluesquare.com ascot.co.uk Pavilion Stakes at Kempton.
Richard Hughes always had the 6-4 favourite on the pace from his low draw, but the Richard Hannon-trained colt was swamped by runners with two furlong to run.
However the son of Oasis Dream found plenty for pressure where it mattered and regained the lead from Bannock with 50 yards to run.
Bannock (17-2), trained by Mark Johnston and ridden by Silvestre De Sousa performed with plenty of credit in second, whilst Ed Dunlop's Burwaaz (4-1) ran on well for Paul Hanagan to take third near the line.
The unlucky horse in the race was Peter Chapple-Hyam's Samminder who travelled very powerfully for Ryan Moore but was continually denied a run and ended the race full of running.
Hannon jnr said of Gusto: "I think he wants to go back up to seven furlongs now.
"He's a real battler and his big aim is the Jersey Stakes at Royal Ascot.
"He's been quite busy, so we might freshen him up for that."
The winner provided Hughes and Hannon with a double following the first race win of Lyric Ace.
