Trained by John Gosden and ridden by Robert Havlin, Utmost (5-1) showed a nice change of gear to repel the challenge of 11-10 favourite Victory Bond by a length and a quarter in the Listed heat over 10 furlongs.
The race was also a Fast-Track Qualifier for the £200,000 Betway Easter Classic on All-Weather Championships Finals Day (March 30), but Havlin first anticipates a Winter Derby date.
He said: "Utmost has been a late-maturing horse. I won on him at Leicester two years ago and we have just been waiting for him to strengthen up. It has taken forever and he is still not the finished article.
"The last day (third at Lingfield in December), he hit the front turning in and got outpaced before staying on again. I was adamant that I wanted to make it a little bit more of a test today and get them rolling earlier. He will probably come back for the Winter Derby now."
Kachy will also be aimed at the big meeting on Good Friday after securing his ticket for the £150,000 Betway All-Weather Championships Sprint Final with victory in the Listed Cleves Stakes.
Sent off the 6-4 favourite for trainer Tom Dascombe and jockey Richard Kingscote, Kachy swooped in the final furlong to claim the lead and had enough in reserve to repel the fast-finishing Kimberella by a short head.
Dascombe said: "I actually thought he had won a bit easier than he had and I was surprised it was only a short head, but he has won and it's great for the owners, who have been big supporters of the yard. They have a Listed winner and a real live chance on Finals Day.
"He has done it from stall nine and stall 11 so far this season and it could be easier, unless he gets stall 12 on Good Friday!
"I don't know what the opposition will be but you would think that, unless something comes back from Dubai, he would have to go into the race with a favourite's chance.
"He will definitely go straight to Good Friday now. He is a better horse fresh and I was worried that running him 15 days apart today would be too much for him."
