Cecil saw Noble Mission take the Gordon Stakes and Chachamaidee triumph in the Lennox Stakes.
Noble Mission, brother of Cecil's famous Frankel, needed a photo to seal victory.
Frankel takes part in the Sussex Stakes on Wednesday looking to make it 12 wins from 12 in his career to date.
Cecil is having treatment for cancer and is unable to attend the meeting.
"Although I am able to train my horses, I'm not quite fit to go racing yet, but I hope to be fully recovered in the near future," he said.
