Owned by the China Horse Club, the son of Street Cry ran very green on debut at Chelmsford earlier in the month and he stepped forward from that effort to finish second at Kempton two weeks ago.
Andrea Atzeni put his mount’s experience to good use here, tracking the leader into the straight before asking him to pick up on the long climb to the line.
Mutadaffeq and Danny Tudhope looked briefly to have stolen a march on the field passing the three-furlong marker, but St Malo was soon organised by Andrea, taking the lead inside the final quarter mile before going on to win with the minimum of fuss.
A physically-imposing horse from a late-maturing family, St Malo should continue to progress with time and experience and he looks a lovely prospect for next season.
Roger said: “St Malo has taken a little time to learn his trade, but he is really getting the hang of things now and I liked the way he galloped all the way to the line here.
"He is going to make up into a lovely horse next season and I hope he is able to contest some nice prizes and reward the patience his owners have shown with him."
