the jockey afterwards was clearlt trying to deflect attention from how the horse ran by criticizing his own performance. the truth is she was getting reeled in from a furlong out, and yes although the jockey had a stinker, she was running on empty the final half furlong. the only difference if the jockey had ridden her out is that she would have won a head as opposed to short head.
when you look at the furlong splits she was fastest between 2 and 1. Maybe she found Ascot 6 furlongs too much for her? When Choisir won back in 2003 he easily won the Kings Stand over 5f but struggled over 6f. also it could have been the travelling as well. or that she just is not as good as they thought her to be.
it was interesting that in build up to race the trainer was complaining that Frankel receives bigger rises in ratings than Black Caviar, suggesting that his horse was being underrated, but then after the race he said that Frankel was the better horse.
If they were to race over 7f on what we saw this week, Frankel would win comfortably. also based on today I would back Frankel to win over 6f, but it would be a more close run thing.
