William is hopeful that Besito can make an impact on her racecourse debut at Leicester (raced 11th June).
The daughter of Kodiac, who contests a 6f maiden, has been pleasing her trainer at home and the team are looking forward to her first run.
William said: “We bought her at the breeze-ups for Tony Foster. She has shown plenty at home and I think she should do herself justice first time out.
“The dogs are barking for plenty of runners in the race so I wouldn’t be surprised if the race turned out to be stronger than the average Leicester maiden.
“But my filly has been very professional in her work at home and I would be disappointed if she doesn’t give a good account of herself.”
