I'm gonna use this post so I can do a profile on Mage.
MAGE Profile: This is one of the most talented horses in this 3 year old crop, however, he is still an unrefined athlete.
Mage has a strong IHD and impressive speed. Everything about his debut was fast. His ears were pinned from start to finish. His body control looked good as he displayed in what we call single-platform IHD speed pattern of motion. (Break from the gate, get to the front, single kick to the wire when asked).
In the Fountain of Youth, at the start, he hit his hind end on the gate and was cut off by Rocket Can in early traffic. In the Florida Derby, he once again his the starting gate which relates to his being overly intense in the starting gate. There is something going on with his start-to-stop sequence, at it probably has to do with his sensory interpretations while standing in the gate. Unlike his second start, he rushed up to try to get tactical position and he tried to do a sustained closing pattern of motion. And it almost worked. He hit the front at the 16th pole, but Forte stayed on better and won by a length. Mage ran huge in the Florida Derby, but his final furlong in 13.19 was not enough to hold off Forte. He appeared to be shortening stride significantly.
Mage is a tenacious, competitive minded horse. There is major physical talent here. The issue is his Herd Dynamic and running style remain undefined. If he can iron out his starting gate issues, he could take another step forward in the Derby. Without a defined pattern of motion, he will likely be left with just winging it. This is a huge task for a horse still trying to figure out who he is.
My comment: They have moved riders to use Castellano. Historically, in the last 5 Derby's Castellano has moved up 3 of the 5 horses that he has ridden. I have heard, but haven't had it verified, they will employ some sort of a cushion on the back of his gate which will not allow him to go backward and it "could" have a bearing on how well he leaves the gate.
