Cornerstone has the strongest overall form profile with an average of 70.0, comfortably the best in the race. His last five reads 63, 86, 82, 59, and 60 — consistently at a high level with two outstanding performances. He won two starts ago with an 86 and the 82 before that confirmed he is clearly the classiest dog here. The concern is trap 2, the weakest draw at A3 435m at 15.2% from 46 runs. In a low-separation race you would normally defer to structural factors, but his form advantage is significant enough — averaging nearly 12 points above the next best — that class should prevail.
