Green Moon won a maiden first time out as a 3yo and then a class 218 handicap impressively, so he cannot be ignored in the race tomorrow, a class 227.
However, among the competition are:
Alrasm, who won a class 100 handicap lto returning a much higher SF than Green Moon, and 6lb better in on handicap terms than Green Moon;
Ameer, who came 2nd by only a head in a class 1354 non handicap on 14 April before weakening towards the end of a 11f race abroad on 8 May. Like Alrasm, he is 6lb better in on handicap terms than Green Moon.
Any of the runners could show further improvement, but I'll be surprised if Green Moon can beat both Alrasm and Ameer, so will be leaving him tomorrow.
