A half-brother to the stable’s brilliant champion Frankel, Morpheus opened his account at the third attempt in the ABG Law Classic Maiden Stakes.
The 4-5 shot swept clear of the opposition in the final furlong to win by four and a half lengths from Elsiniaar and complete a treble card for jockey James Doyle.
Lady Jane said: “He did it so well. He has taken time to get his act together, but that was very pleasing, wasn’t it. And James gave him a great ride.”
Doyle said: “It is nice to be part of that. Sir Henry was a trainer I’ve always admired. I was hoping one day I’d get a ride for the stable.”
The Warren Place team struck again just 10 minutes later when Songbird won at Yarmouth.
Doyle’s first success on a day of sunshine, heavy rain and a thunderstorm at the Colwick Park course came on Jubilant Queen in the Corona Handicap Division One.
The well-backed 3-1 favourite, trained by Clive Cox, powered clear in the final furlong to beat Aaranyow by a length and a half.
“I was a bit concerned the ground was going to be against her, but it came right with this rain,” said Wally Swinburn, whose Genesis Green Stud bred the filly, which is co-owned by his wife Doreen.
“She is as honest as the day is long and I’m hoping she will make a nice broodmare.”
Doyle brought Man Of Plenty (3-1) from last to first to grab the Coors Light Handicap by a length from Rowlestone Lad.
“We got lucky. They’ve had lots of rain since racing started. It was touch and go whether he would have run had it been fast ground. That’s made the difference,” said trainer Ed Dunlop’s travelling head lad Robin Trevor-Jones.
“He was an unlucky horse when a horse fell over in front of him at Goodwood so he deserved to win a race.”
