Connections of Sweetheart are keeping their fingers crossed she makes the cut for next week's Ascot Stakes following victory in the Betdaq The Betting Exchange Handicap at Folkestone.
The daughter of Sinndar, a dual winner over hurdles, was sent off the 5-2 favourite to follow up a recent Goodwood victory but was under the pump some way out under Neil Callan.
However, she was in no mood to give up without a fight and knuckled down well inside the final furlong to score by half a length from market rival Tribe.
The winner's owner Ron Huggins has already tasted Royal Ascot success thanks to the Gold Cup victory of another smart stayer in Double Trigger, and he would love to be represented at the prestigious meeting once again.
"She's a fantastic trier and she has done really well over hurdles and now on the Flat," said Huggins.
"She went up to 140 over hurdles, was second in a Grade Two and she's a lovely horse.
"We didn't think she went on fast ground but she's been a bit of a revelation as she's done well at Goodwood and here again today.
"I don't think she'll get in the Ascot Stakes as there used to be 30 runners in the race and they've reduced it to 20 now, so she probably needs to be nearer 80 than 70.
"It would be great to get in there, but she would probably get in a two-mile-five-furlong race at Goodwood so that would be good as well."
Billy Beetroot secured his second victory in as many days in a tight finish to the Hythe Claiming Stakes.
The Stuart Williams inmate, a ready winner at Brighton on Sunday, was sent off a 13-8 favourite to take this lesser event and gradually wore down Papillio to score by a neck.
Williams said: "He's tough and consistent but he has just been struggling to get his head in front. Hopefully yesterday has given him some confidence.
"This didn't look a great race and you've got to take your opportunities with these horses."
Winning jockey Andrea Atzeni went on to complete a double in the concluding Lipscomb Abarth Handicap as 7-2 chance Confide In Me turned over odds-on favourite Jo'Burg.
Pic Up Sticks rolled back the years when showing his younger rivals the way home in the Eastwell Manor Handicap under George Baker.
The 10-year-old had been without a victory since September 2007 but sent off at 7-1, Brendan Powell's charge cruised to the front inside the final furlong and only had to be pushed out to beat Music Box Express by three-quarters of a length.
Baker said: "He is 10 years old now but Brendan's horses are in good form and that has carried through to him.
"I took it up in the final furlong and he is an old professional - if you keep him sweet he will win his races."
Aroundthebay (15-8) bounced back to winning ways with an authoritative display in the Try Betdaq For An Exchange Handicap.
Harry Dunlop's filly had finished well down the field over seven furlongs at Newbury last time but dropping back to six, she was not particularly hard pressed to beat Rio Royale by a length.
Dunlop said: "I thought a lot of her but she's a filly who is a little bit quirky and she has a lead pony in the morning all the time.
"I was just delighted to come here for a nice confidence booster and it's nice to get a filly like this back on a winning way."
Sagunt stretched well clear of his rivals to take the Bet Asian Handicaps - Betdaq Handicap with the minimum of fuss.
The Sean Curran-trained chestnut was sent off the 11-4 favourite to supplement a victory at Warwick last time and eased clear of his rivals to score by two and a half lengths from Carmela Maria.
Simon Callaghan's Morning Sir Alan (9-2) got off the mark at the eighth attempt in the Lemond & Gabriel Friendship Across The Water Median Auction Maiden Stakes.
