First Sitting just held on for Listed honours in the Matchbook Betting Exchange Festival Stakes at Goodwood.
Berkshire made the running in the mile-and-a-quarter race, but he was overtaken by the eventual winner inside the final quarter of a mile.
Chris Wall's 16/1 chance looked home and hosed under Gerald Mosse, but last season's Cambridgeshire winner Spark Plug flew home at the death, with only a nose in it at the line.
Roger Varian's good form continued in the Basketmakers Company Celebration EBF Fillies' Novice Stakes, as Madeline (7/2) showed the benefit of her debut fifth to beat favourite Billesdon Brook.
Always travelling well in the hands of Andrea Atzeni, the Kodiac filly quickened clear two from home and, while still green, had enough in hand to hold off Richard Hannon's runner-up.
After a winner at Haydock with Rusumaat, Ben Linfoot landed a Value Bet double when Sutter County (9/1) won the Winners Are Welcome At Matchbook Handicap.
It was also a double for Atzeni, who was at his best here as a well-judged ride saw the partnership fend off Medamin, another runner-up for Hannon.
Second Step (7/2) took the Listed Smarter Bets At Matchbook Tapster Stakes.
Previously winless since the Jockey Club Stakes in 2015, a switch from Luca Cumani to Roger Charlton paid off at the second time of asking for the six-year-old.
Winning rider Jamie Spencer swept down the outside along with 2/1 joint-favourite Desert Encounter, and his mount always looked to be doing enough when hitting the front.
Spencer had suffered a troubled run in the opener, going down narrowly aboard Spark Plug having been trapped on the inside, but this time went for the centre of the track and it paid off.
It was another big run from the consistent runner-up, who has placed on all eight starts dating back to a maiden win at Musselburgh in 2015.
Atzeni completed a treble when Top Tug beat High Secret in the Gentleman's Measure In Memory Of Phil Wiggins Handicap.
Alan King's horse, sent off a well-backed 100/30 favourite, got the better of the Paul Nicholls-trained challenger in a finish fought out by runners from two of the biggest National Hunt yards in the country.
