Prince Of Wales's Stakes (Group 1) 1m 2f, 4yo+
So You Think registered a tenth success at the highest level as he denied Carlton House a fairytale win for the Queen at Royal Ascot in her Diamond Jubilee year.
The two-and-a-quarter-length win took So You Think through the £5 million career earnings mark, completed a double on the afternoon for trainer Aidan O'Brien and provided his son Joseph with a first win at Royal Ascot.
Sent off the well-backed 4-5 favourite, So You Think managed to go one place better in the race than last year when he was beaten at 4-11.
Carlton House had looked momentarily like he was going to post a popular win as he came with a challenge under Ryan Moore up the rail but he was never able to head So You Think and finished just a half-length in front of the third-placed Farhh.
