Great Dame made the most of her low draw when gamely holding on to victory in the Stellar Group Lily Agnes Stakes at Chester.
After turning in a disappointing effort on her debut at Redcar, the daughter of Dandy Man supplemented her recent success at Ripon in the five-furlong conditions contest.
Making an electric start from stall three, the 7-2 chance was soon in front and after being kicked on early in the home straight, she had just enough to deny the unbeaten Iva Reflection by half a length.
Following the race the winner was introduced at 33-1 for the Queen Mary at Royal Ascot.
Winning trainer David O’Meara said: “She is very tough. I actually thought she would run a nice race first time out, but she didn’t. Although she was green, she made up for it at Ripon and has done it nicely today.
“It always helps to have a low draw and a handy position here and Danny (Tudhope) gave her a great ride.
“We might have a look at the Marygate at York. We will take it one step at a time, but Ascot is on everybody’s agenda at some point.”
Leodis Dream showed no sign of his progression slowing down after completing a five-timer with victory in the Boodles Diamond Handicap.
The son of Dandy Man shrugged off a 4lb rise in the weights for his latest win at Sandown when defeating Recon Mission by half a length to complete doubles for O’Meara and Tudhope.
The winner was cut from 10-1 into 6-1 favourite for the Epsom Dash, while Ladbrokes offer 10-1 for the same race.
O’Meara said of the 9-2 winner: “He spent the whole race lugging out to the right, but he got to the front really easily. Danny said he didn’t like the track and that he wasn’t in love with the ground. He just keeps on getting better.
“Today I’d say he has done more than he ever does. He got to the front easy and I thought he would win by three or four lengths. He idled a bit in front. If he had been drawn one and had a nice trip next to the rail he would have been more impressive.
“We will see how he is, but that (Dash) will come under consideration I suppose.”
Future Investment saw off long-time leader Bo Samraan by a length and a half in the SportPesa Maiden Stakes.
Beckett said: “I was the underbidder as a yearling to (former trainer) Jeremy Glover, so he came and found me afterwards and said ‘well I better send it to you’.
“He is a lovely horse and loved this ground. He ran above expectations on debut. His sister (Mountain Bell) won the Stand Cup round here and I just thought it would suit him.
“I would say we will step him up to a mile and a half under a penalty in a novice race.”
Lihou (8-1) got the best of a tight finish to the Homeserve Handicap while Gossiping (8-1) lifted the closing HR Owen Maserati Handicap.
