Awesome Act is a smart horse who runs in this event and he needs as much rain as possible. You can forget his last run because he lost a shoe and the race was run at a dawdle. He needs an out and out gallop to be seen at his best; he should get that in this race!!
Also, this is an English horse so most of the US punters will not be interested and this means a bigger price. There is also the chance of an arbitrage on this horse. Check the live shows from the US and ensure you are watching the Pari-Mutuel/Tote odds. These are generally must bigger because the Americans ignore our horses. The UK bookies will offer skinnier odds so ensure you stress it is Part-Mutuel odds you require.
The basic idea will be to back it with the Pari-Mutuel odds and then lay it off on Betfair

The race is run at 11:24 UK Time at Churchill Downs
Good luck!
