Marcus,
At the weights, Melhior Inda would NOT need a three point top. She gets in at 115 pounds, getting 8 pounds from Sand Springs and 6 pounds from Wonder Again. She is about 2 1/2 points slower than Wonder Again and is getting about 1 1/2 points in weight. So she would need a one point top, if they got the same trip. Since Melhior Inda is a developing 3 year old, she is much more likely to run a new top than Wonder Again (as JB points out in the ROTW). To me, that makes Melhior likely to run a similar race to WA, barring ground loss. With neither having much tactical speed and WA drawing inside, that gives WA the edge in my book, but Melhior could be tough here.
