Brad Rawiller says French Emotion can measure up to stakes grade after the mare made it three straight midweek victories at Sandown.
Rawiller has been aboard the Chris Waller-trained French Emotion for all three wins, including her latest in the Premier Signs Handicap on Wednesday.
"I'm pretty confident she can get to black type," Rawiller said.
"Even at my first ride on her she broke 32 (seconds) for the last 600 metres and you don't do that unless you have something there.
"It showed it wasn't a flash in the pan win as she's done it three times this time in."
Sent out the $1.50 favourite, French Emotion scored by three lengths from Redasun ($8) with Saone Et Loire ($26) a length away third.
Rawiller says one of French Emotion's greatest attributes is her ability to take any spot in a race and then quicken.
"She's a beautiful horse for a jockey to ride," he said.
"You can put her wherever you want and she's got that lovely turn of foot and she's the first horse to pull up.
"She knows when she's done her job underneath you and she comes back and wouldn't blow a candle out."
Justine Hailes, who presides over Waller's Melbourne stable, said the mare appreciated the firmer tracks in Melbourne after being beaten in maiden grade in Sydney on heavy tracks last campaign.
She suggested the stable may look to the Brisbane winter carnival with the mare.
