Trainer Tim Butt isn't pushing the panic button even after Mah Sish raced like anything but a Hunter Cup winner at Oamaru on Sunday.
The dual group one winner was the first horse beaten in his comeback race and finished seventh of nine after leading in the middle stages.
While winner Franco Ledger had to break 54 seconds for his last 800m and the runner-up Four Starzzz Flash has gone to another level, the fact Mah Sish was beaten so easily is a concern for punters who have taken fixed odds about him for November's New Zealand Cup.
However, Butt says Mah Sish will improve quickly and the race may be a wake-up call for other established open-class stars, like Terror To Love and Christen Me.
"When you see horses like Franco Ledger breaking 54 for their last 800m you realise how hard the open-class season is going to be," said Butt.
