Next best: 4.55 Market Rasen
Dark Profit is of interest in the Argyll Holidays: Why Go Further? Handicap at Ayr.
The six-year-old enjoyed a fine campaign for Keith Dalgleish last season, winning at Ayr, Carlisle and Musselburgh.
He flopped on his final outing of 2017 last October, but ground conditions at gone against by that stage and he should be far more at home on the fast surface he encounters on his return to action.
Dark Profit is only 4lb higher than his last winning mark and is certainly capable of adding to his tally if fit enough after a lengthy absence.
Haymarket should also be supported in division one of the Create Great Family Memories Together Handicap.
Mike Smith's nine-year-old had been out of form, but he looked in good order over this course and distance last month when beaten a head by Thorntoun Care in an amateur riders' handicap.
Haymarket returns to Ayr off a 2lb higher mark, but the two-time course scorer remains well treated on his winning form at Musselburgh last summer.
Despite his advancing years, there are more races to be won with him.
Keep an eye, too, on Lexington Place, who runs in the Last Minute Luxury Hot Tub Breaks Amateur Riders' Handicap.
Ruth Carr's inmate was an eyecatcher at Leicester last time and looks favourably handicapped, even in spite of the burden of having to carry top weight.
Lexington Place also knows the terrain well, having twice won over five furlongs at Ayr during a fine career.
Brave Eagle can complete a hat-trick in the most valuable event of the afternoon at Market Rasen.
Nicky Henderson's charge won at Newbury last December before struggling in two better races at Cheltenham in the spring.
However, he has regained momentum with successive wins at Plumpton and Southwell and while the official winning margin of his latest triumph was only half a length, he was value for a good bit more.
He appears the type of horse who only ever does the bare minimum, which is useful from a handicapping perspective, and a 3lb rise could prove generous ahead of his appearance in the £20,000 Don Noble Handicap Hurdle.
