Nostrum heads our ratings at 88, four pounds better than Walsingham on 84, and that edge is enough to make him our selection in a fairly open Class 4 nine-furlong contest at Musselburgh. Walsingham is the chief danger, while Kaleido and Priapos, both on 81, sit a further three pounds back and cannot be dismissed if the leader falls short. The bottom end of the field looks a shade weaker, with Humble Spark, Sunriseontheboyne and The Stone Power all rated 77 or lower, so the race should be settled among the top four. Nostrum gets the vote, though this is a competitive heat and the margin is only modest.
