The son of Mastercraftsman was supplemented for the mile contest on Monday having won both his previous starts to date.
Owned by Paul Smith, he won a maiden at Newbury on his first start before stepping up on that to take the Autumn Stakes at Newmarket two weeks ago.
Roger has been pleased with him since that run at we are exciting about running him on Saturday.
He said: "Kingston Hill has done nothing wrong and has won both his starts. I have been very happy with his condition since he won the Autumn Stakes two weeks ago.
"The trip and ground should be fine and, although this is another step up, I am confident that he will be there or thereabouts."
Steps has had a tremendous season and he will have his last run of the year in the £50,000 handicap on the same card.
Last seen winning the Rous Stakes at Ascot, Steps has been in good form since but faces a tough assignment under a big weight.
Roger added: "He has been a star all season and produced a career best at Ascot last time. He has run well at the track and soft ground is ideal but it will be very hard for him off such a big weight."
Soaring Spirits makes up the trio when he contests the seven-furlong apprentice handicap under man-of-the-moment Osisin Murphy.
Roger said: "The ground should be fine for him and he seems in good form."
