Undefeated in his first two starts in Melbourne, the Matt Laurie trained I Am Invincible colt Vinrock was heavily backed to beat local glamour colts Wodeton and Rivellino in the $1million Group I ATC Sires Produce Stakes (1400m) and duly got the job done with a tenacious display at Randwick on Saturday.

A full sister to Group I winner Mizzy, Dorrington Farm’s homebred filly She’s Got Pizzazz was a stakes-winner in Melbourne last spring and added further to her considerable worth when dropping from the clouds to win the Group III ATC PJ Bell Stakes (1200m) at Randwick on Saturday.
