Sundees Son will be asked to add a new weapon to his growing arsenal this week and it is one that could ultimately win him the Harness Jewels.
The last-start Rowe Cup winner has been the surprise package of the trotting season, his late-season group one double giving him a shot at the Trotter of the Year title.
He could almost put that battle to bed if he wins the 4-year-old Ruby at Addington on Saturday week and a crucial step will be the official Jewels trials on the same track this Saturday.
While Sundees Son was stunning coming from well back to win both the Anzac and Rowe Cups he can't afford to be giving the likes of Winterfell, Majestic Man and King's Landing a big start over the 1980m mobile. So Sundees Son is, draw permitting, going to be asked to use his gate speed at Saturday's trials.
"We would like him to be able to run the gate this week to give us the option to do that if he draws well at the Jewels," says trainer Robert Dunn.
