Canningvale trainer Jamie Marsh has copped opposite ends of the boxes in the $6125 Tab Cannington Winter Maiden Classic (530m) tonight.
Coloccini, who ran second at his race track debut, has drawn pole position while last-start winner Archie Doodah will jump from the pink box.
Coloccini appeared unlucky last week when two lengths behind faster qualifier Industry but will be improved by the experience and has the ability to turn the tables.
"Very happy with the way he went first up," said Marsh.
"His trial win was out of the red box so to go out from the seven on debut and run second was pretty encouraging."
Archie Doodah has displayed good early form and has yet to finish out of the money with one win and four placings from his first five starts.
Last week when he broke his maiden status in good style when he won comfortably from Angel Lee in 31.25sec.
The race was a little messy early but once he knuckled to the task and gained clear passage he looked impressive.
"He stuck to the rails and once he snuck through he won well," said Marsh.
"He is not blessed with the same ability as Coloccini but he tries hard each and every time he steps out.
"It's hard to split the pair but a leaning towards Coloccini who has the better draw."
