If Reese on the 2nd horse doesn't slow his own momentum by trying to shove a tiring horse and keep following Rue, he slides out in 30-40mtrs and would have sailed past him.
Trying to shove tiring horses at the pointy end of a race, now that's using your noggin if I've ever seen it - not!
What's McCarthy done wrong? He's held his line on a tiring horse. (Seemed to pull the entire trip) He did have a runner to his outside wheel, what would you like him to do, drift out and knock the outside horse down?
Reese did himself no favours wanting to shove at the furlong when not sufficiently clear. As I said, if he keep's following Rue for 30-40mtrs more at the most, he'd have slid out, never losing momentum and waved bye bye, plain and simple.
