RUMSTAR had several of these in behind when winning the Palace House Stakes at Newmarket on return, and the manner in which he cruised through that race suggests he's the type to develop into a top-level sprinter this season. Sure to have tightened up (he was carrying condition) for that outing, he's fully expected to record another win on his way to the King Charles III Stakes at Royal Ascot. American Affair and Electric Storm may be the two to follow him home.
