Our Dynamite's impressive debut victory wasn't missed offshore.

The three-year-old was untested to win by five and a-quarter lengths at Trentham last month and that performance has drawn the interest of parties from Singapore.

Our Dynamite is an acceptor for the Westmere Bulk Spreading Ltd 1200 on his home track at Wanganui on Sunday, but a start hangs in the balance.

"He's only 15 hands, but there's a couple of people interested in him and if he is sold then he won't run," trainer Wayne Marshment said.

Our Dynamite's effort at the first time of asking in the hands of Lisa Allpress was exactly what Marshment had been expecting.

"After he got broken in we gave him two jump-outs and he won both of them by big margins before we turned him out," he said.

"When he came back Lisa won another jump-out on him and I couldn't see him getting beaten at Trentham."

By Danehill Dancer's Group One-winning son Alfred Nobel, Our Dynamite is raced by his breeder Kevin Mahoney, formerly of Wanganui and now based on the Gold Coast.

Meanwhile, stablemate Stealth Giant will make his first appearance in Sunday's Faulding's Sound Maiden 1200.

The Singapore-owned son of Red Giant is out of a half-sister to former champion Singapore sprinter and multiple Group One winner Rocket Man.

"He galloped well on Wednesday and he won't mind any rain," Marshment said, "He's a lovely horse, but he was hard work early on."
