Isaac Newton tops our ratings after a gutsy neck win in a Listed contest at Navan last time, finding reserves despite meeting interference in running — a stable with a proven record in this race and an elite booking combination in place. Purview is a very serious rival: his six-length Listed victory here last time, produced with impressive authority, marked him as a horse of real ability stepping up in grade; Hotazhell, a former Group 1 winner who was headed only in the closing strides of a Listed race at Navan recently, rounds out the key dangers. Isaac Newton is our selection.
