Phil Gough and John Fitzgerald’s tracker has really come into his own since stepping up to the testing 600yd trip.
Remarkably the son of Crash was a drifter in the market as Oneco Cool attracted hefty support, but in the race itself there was simply no opposition to the favourite.
Both Sparta Maestro and Oneco Cool came away racing, although the former was simply too sharp for his rival.
Displaying big early dash, Sparta Maestro opened up a commanding three length lead before the turn. From that point there was little chance of anything other than an easy victory for the powerhouse.
Oneco Cool stuck to his task in second, but Sparta Maestro was in a league of his own and he pulled further and further clear to land the €5,000 prize by seven and a half lengths in a sensational 32.10.
Afterwards John Fitzgerald, who jointly owns the star tracker with trainer Phil Gough was in no doubt as to how good he is, “He is a once in a life time dog, a dream dog. I haven’t had better.”
When asked what the plans were for Sparta Maestro, Fitzgerald addedL “We’d like to keep him running. There a couple of things coming up before the end of the year. Ill have a chat with Philip (Gough) tomorrow, possibly the Leger, the Night of Stars here and maybe the Waterford Masters.”
Elsewhere on the Shelbourne card he most eye-catching run came from Ruthless Man as he ran away with an Open 525 in 28.16.
The final of the valuable Billy Mulvaney Snr and Jnr Memorial 525 saw the Larry Mason trained Airlie Jet lead home his kennel companion Forest Rock.
The former charged to the front down the back straight to see off Forest Rock by a length and a half in 28.48.
