Dalgleish, the former Borders jockey who tasted success at the Royal meeting with Mark Johnston's Fantastic Love in the King George V Handicap in 2003, is considering the Windsor Castle Stakes for the promising two-year-old.
The Kheleyf colt trotted up by six lengths at Newcastle three weeks ago after finishing second in his two previous starts.
"He came out of that race well and seems to be growing up a bit," said the Carluke-based trainer. "He was a bit naughty first time out at Musselburgh but he seems to have left that behind. The form of his races is good and is working out well. He couldn't have done it any better that day at Newcastle. We are not going to get carried away, but he seems a nice horse.
"We've had discussions with the owners and he will be entered at Ascot, but we're not 100 per cent sure where we'll go next. With the way the form is working out I'm sure he'll be well able to take his chance there.
"The Windsor Castle is probably the race we'd be looking at. We'll stick to five (furlongs] as he's got plenty of speed.
"To get a two-year-old like him in my first year training is great and I hope he can do the business in better races. It might help push me along."
Meanwhile, Robin Bastiman is to have one of Borderlescott's hind legs checked out following a bizarre incident in the Temple Stakes at Haydock on Saturday. The nine-year-old suffered bruising and swelling when he was stopped in his tracks for a few strides after being hit by what looked like a piece of cloth from a horse in front. Despite that interference, Borderlescott still finished fourth to Sole Power in the Group 2 dash.
