The son of Elzaam, owned by Chloe Baines, was a creditable sixth in the Windsor Castle Stakes at Royal Ascot before winning a novice event at Lingfield last Saturday in good style.
He has bounced out of his Lingfield win in great shape and deserves to take his chance back up in grade.
Roger said: "Pretty Vacant is a fast, talented juvenile. He followed up on his good run in the Windsor Castle with an impressive success on Saturday.
"I have been pleased with him since. He is well drawn today and ought to be very competitive."
Andrea Atzeni rides and the pair will break from stall one.
