One-time $100 pop Mah Sish has Inter Dominion bookies worried after Ballarat and Hunter Cup triumphs Kiwi pacer Mah Sish has TAB fixed odds bookies sweating after he was backed at as much as $100 two months ago, whereas now he is rated the $5.50 third favourite for the Inter Dominion title. CHAMPION driver Anthony Butt says one of the smartest plunges in Inter Dominion history is right on target. And one-time $100 chance Mah Sish could get even shorter for the March 3 final after his heat at Menangle tonight. The Kiwi pacer has TAB fixed odds bookies sweating after he was backed at as much as $100 two months ago, whereas now he is rated the $5.50 third favourite for the title. The money trail started after Mah Sish arrived from New Zealand looking more a bit player in the series but he has skyrocketed up the markets with wins in the Ballarat and Hunter Cups as well as a second in the Victoria Cup. Butt, one of the most successful reinsmen in Inter Dominion history, can only see that trend continuing in tonight's supplementary heat at Menangle, as five heats are crammed into two hours across four cities. "He is spot-on for this week and, to be honest, I expect to lead and win," Butt said. In saying that, I'll have a plan B and C but I don't think I'll need them. Mah Sish has blossomed as many other big names in the series have come across the problems often brought on by the rigours of Grand Circuit racing. "He has gone ahead at the right time and I wouldn't want to be driving anything else for the final," Butt said. TAB harness bookie Mick Ramsay admits he will be cheering against Mah Sish as well as dual Interdom champ I'm Themightyquinn, who contests tonight's Perth heat. "We had a few smarties get on Mah Sish at the $100 but all the money this week has been for Quinny to win the final," he said.
