It's all down to the new improved handicapping system (with added organic botanicals!) we have introduced in Australia which complements the equally new and improved handicapping system so loved (or loathed) in NZ. Another Masterpiece is a very good horse, an outstanding 2 year old that gets "rewarded" with a R100 rating at home. The lack of fast class options there consigns him to receiving wind burn every time Self Assured whooshes past him.
The same applies to Princess Tiffany, and you saw her say thanks for the change of scenery tonight. But she has a NR120 rating, the near complete absence of mares races in NZ being the reason she is here. Reality is, once a good mare turns 4 in NZ they are pretty well buggered. It's come to Oz or go to US or stud.
The bigger mystery is how dumb and uninformed are the punters that let these two start at $4.90 and $3.70?
