Trainer Gerald Ryan has the distinction of training Myboycharlie's first Australian winner and has the chance to further boost the sire's profile with Our Penny Girl who is entered for Rosehill on Saturday.
Charlie Boy's come-from-behind debut win over the highly-touted Windjammer at Rosehill on Saturday stamped him as one of the better 2-year-olds produced this season.
Our Penny Girl will run in a barrier trial at Rosehill today, after which Ryan will decide whether she goes to the races this week.
"I'll see how she goes tomorrow before I decide whether she runs on Saturday," Ryan said yesterday.
"Triple Crown Syndications bought her and Charlie Boy and I really like them as types.
"They are strong horses. She is not as big as the colt but she is still strong.
"Glyn Schofield will ride her in the trial and on Saturday if we decide to race her." A group one-winning juvenile in France, Myboycharlie stands the Southern Hemisphere season at Vinery Stud.
Our Penny Girl was one of just six 2-year-old fillies nominated for the 1100m race with David Payne entering three, including Artistic Lass who finished fourth to Charlie Boy.
