The Simon and Ed Crisford-trained filly arrived in fine fettle following two comprehensive victories and once again provided the winning formula at Lingfield this afternoon.

The pace looked a generous one as recent Wolverhampton winner Miss Bluebelle set out to make the running and it soon became apparent those towards the rear of the field were by no means poorly positioned. Miss Bluebelle began to feel the pinch with a furlong to run and with a taking turn of foot, Oh So Grand soon swept by her rivals down the middle of the track to take up the running with half a furlong to travel under Jack Mitchell.

Queen Regent ran on strongly from the rear of the field to take second but in all truth, she was no match for the 11/8 market leader, who eventually prevailed by a commanding one-and-a-half-length winner.

33/1 shot Dayzee finished a further two and three-quarter lengths behind in third.

Simon Crisford, who saddled Al Agaila to win the race last year, told Sky Sports Racing: "I think she's still improving. I mean obviously we've seen in every race she's been on an upward curve, and she seems to be really developing into a smart filly.

"Hopefully she can be a Group filly for the summer when we get her on turf. I would be inclined to keep her over this trip, a mile and a quarter that suits her well, but she's nimble and light on her feet – she's not one of these galumphers, she's got something about her.

"I really don't know (what is next), this race was always the target, so I haven't thought even thought about what's happening tomorrow, let alone in a few weeks' time.

"We will have a look, see how she is, how she comes out of the race. There could be races coming up for her, obviously you've got (All-Weather) Finals Day and stuff like that. Who knows – we've just got to work it all out."
