There is an even split between the fillies and males in Saturday's Champagne Stakes on numbers, but when it comes to getting results in the major juvenile races this season there has been no such equality.

Fillies have won all three Group One two-year-old contests this year.

Such has been their dominance, they filled the first seven positions in the Golden Slipper won by Mossfun.

Only Unencumbered's Magic Millions triumph has given the colts and geldings some swagger but with fillies holding the top two positions in Champagne Stakes betting, the males face a challenge to buck the juvenile trend.

Gerald Ryan will saddle up two fillies, favourite Peggy Jean and Black Opal Stakes winner Lucky Raquie.

He will also start Bachman, a nicely bred All American colt out of top racemare Ain't Seen Nothin' whose stud value would soar if he could snare a Group One two-year-old victory.

"It would be nice to see Bachman win. He would be the only colt to win a Group One (juvenile) race this year. The fillies have dominated," Ryan said.

Bachman makes appeal on the strength of a last start 2-1/4 length victory over Scratch Me Lucky while the same horse ran Peggy Jean to a half-length in the Sires' Produce Stakes.

Ryan concedes the form through the Paul Perry-trained colt points to Bachman holding an advantage but he argues Peggy Jean is yet to peak.

He is also mindful a victory would make her the only dual Group One-winning two-year-old this season.

"She hasn't done anything wrong and I think she will improve from her two runs," Ryan said.

"And if my filly wins on Saturday she is entitled to be the two-year-old of the year as the winner of the Sires' and Champagne."
