"Catchy's come out and won a Group Two, Thronum's run really well and there's a couple of others as well, including this fella.
"His last start was a forget run and Craig (Williams) made an early, decisive move that won him the race.
"It's just fantastic to get a win with him."

The 135th stakes-winner for Fastnet Rock, he is the best of five winners from Dame Blanche and is a half-brother to the dam of Group III winner Sweety Dream.
