There has always been a theory about Mach Three right from the time his first crop hit the track in North America.
It was that his colts were top class but that his fillies weren't up for the fight on raceday.
Even after the outstanding filly Monkey On My Wheel 1:49.3 ($1,475,494) put that theory to the sword in North America, it was a reputation that still prevailed until recently in the southern hemisphere.
Fillies by Mach Three were passed over at sales time in Australasia while his colts were keenly sought after.
Standout fillies in Australia such as Shake It Mama 1:54.7 ($254,568) and Rosa Mach 1:56.2 ($237,237) and even better ones in New Zealand such as Joyfuljoy 1:51.3 ($480,411) and Millwood Meg 1:53.5 ($415,667) did little to change the view that Mach Three fillies were not as good as the competition.
But the last two seasons in New Zealand have finally laid to rest that fallacy with regards to Mach Three fillies.
First up was the champion filly Venus Serena who was 2 year old filly of the year last season, winning five from eight and taking a time of 1;54.7 on her way to winning $265,782.
Coming back bigger and stronger at three, Venus Serena has raised the bar for 3 year old fillies in New Zealand. Records have fallen all season as she has won nine from twelve, lowered the mile record to 1:52.1 and won $399,104 in the process.
While Venus Serena was destroying her 3 year old rivals, the 2 year old fillies division was taken by storm by the brilliant Supersonic Miss 1:54.1 ($137,128).
Brought out of the Australian Gold sale in Melbourne by Merv and Meg Butterworth for $30,000, she was placed with their New Zealand trainers, Mark Purdon and Natalie Rasmussen and has been a star from her first start.
A win in the Group Three $25,000 Leonard Memorial first up convinced her trainers to send her to Australia for the Australian Pacing Gold series where she won her heat and semi with ease before ending up trapped in the trail in the final, finishing a hard held fourth.
Freshened and returned to New Zealand, she ran a lovely second fresh up after sitting parked in a 55 second last half at Auckland and that topped her off nicely for the Jewels the following week.
Drawing wide on the second line, she was wide on the track for the first 1000 meters before finding the death at the 600 meters.
From there she raced away in the straight to win by two lengths in a new New Zealand record of 1:54.1 and put the disappointment of the Australian Pacing Gold well behind here.
So now Mach Three has the leading fillies in both the two and three year old divisions in New Zealand this season.
The yearling sales have changed as well with this years fillies by Mach Three keenly sought after.
Not surprisingly, Mark Purdon brought a couple of the dearer fillies. He paid $72,000 for the filly from Northern Franco and $70,000 for the filly from Gentle Anvil while fillies from Millwood Pride ($65,000) and Alta Valencia ($52,500) also brought good money.
It has been a big turn around from earlier years and with the ongoing success by Mach Three fillies, they can only get dearer from here on in.
