Weight relief may have been the deciding factor in a short-margin result in the Oamaru Cup (1600m) at Ashburton yesterday.
The race was taken out by the Tony and Lyn Prendergast-trained Trudeau, who nosed out King Cougar into second, with Owen Patrick a head back in third.
The 5-year-old son of Pins was initially set to carry 56.5kg, however, with a number of jockeys unable to make the weight, the Prendergasts elected to utilise apprentice jockey Tina Comignaghi's 1kg claim.
"It was really satisfying to get the win," Tony Prendergast said.
"There was a real saga over riders. Jacob Lowry, who normally rides him, couldn't make the weight at 56.5kg. He gave it a fair go, but he was a kilo over.
