Owned by Jon Collins, Chris Fahy and Stephen Piper, the three-year-old jumped smartly under Harry Bentley and established an uncontested lead heading into the bottom bend.
Harry wisely increased the tempo passing through the half-mile marker, and while Henry The Explorer laid down a sustained challenge inside the two, Absolute Zero continued to find readily for pressure, establishing a length and three-quarter advantage at the line.
The son of Cape Cross was having his first start at the trip having previously shaped promisingly in a competitive nine-furlong handicap at Yarmouth.
Roger said: “Absolute Zero has certainly improved for the step up to middle-distances and he should continue to progress at the trip.
“Quick ground is important to him and he responded pleasingly to the positive tactics Harry employed so well. He might even stay further as the season progresses and I don’t think he has done his winning yet.
“Congratulations to Jon, Chris and Stephen on a well-deserved success.”
