The first Jewels markets opened yesterday, with Miracle Mile placegetter Arms Of An Angel rated a $1.45 chance to become the first Australian-trained winner of a Jewels.
She is a hot favourite for the four-year-old mare's division. The three-year-old male pacing market was the other opened yesterday, with Chase The Dream a $2.50 favourite.
