The first selection of the afternoon from Hong Kong comes in the Group One Hong Kong Vase and the British raider Pyledriver is primed to run a big race from stall 3.
The now four year old was a real success story for the fairly small yard last term having made his seasonal debut in June when finishing second at Kempton, but since then improving with every run and showing he is a real black type contender.
He headed to Royal Ascot for his second start of the season and he was a shock winner of the Group Two King Edward VII Stakes.
The colt was given a Derby entry and went to Epsom but having being bumped in the big field early on he ran no race and as a far as Muir was concerned they drew a line through that run.
He proved how special he can be next time out when taking the Group Two Great Voltigeur Stakes at York's Ebor meeting, being eased down in the final stages.
The St Leger was next on the agenda and with many pundits fearing he would not stay, they were proved wrong as the three year old finished a length third behind winner Galileo Chrome.
Although seeing out the marathon trip his trainer believes he is best over 1 mile 4 furlongs, but he did not give his best running on his final start of the season when only seventh of 10 in the Group One Champion Stakes at Ascot.
Back for another season this term the son of Harbour Watch finished a decent second in the Group Two Jockey Club Stakes at Newmarket behind the smart Sir Ron Priestley.
With that run under his belt Muir, as ever, was bullish about the chances of his star in the Group One event at Epsom and in a very gritty fashion, he got back up late on when passed by Al Aasy to land the Coronation Cup.
A setback saw him miss some big engagements, but the camps targets turned to this event and ahead of it he had a prep run at Lingfield in the Listed Churchill Stakes where he narrowly won, with his class telling all.
He has travelled over well and is primed to go close.
