Group One winner Sizzling is a step closer to a return to racing after winning a Doomben barrier trial on Tuesday.

Partnered by regular trackwork rider Patricia Gesler, Sizzling overhauled Spot The Rock to win by a head.

His winning time of 49.95 seconds was the fastest of the eight heats held over 820 metres.

The four-year-old is scheduled to resume in the Group Three Show County Quality (1200m) at Warwick Farm on August 24.

After the Show County, trainer Kelso Wood plans to start Sizzling in the Group Three Tramway Stakes (1400m) at Randwick on September 7 before the Group Three Bill Ritchie Handicap (1400m) at the same track a fortnight later.

Sizzling's main goal in Sydney is the Group One Epsom Handicap (1600m) at Randwick on October 5.

All going well, the entire then will head to Melbourne where Wood will aim him at the Group One $3 million Cox Plate (2040m) at Moonee Valley on October 26.

Sizzling won the Group Two Queensland Guineas (1400m) at Eagle Farm on June 1 before ending his winter carnival campaign by finishing seventh to Linton in the Stradbroke Handicap over the same course and distance a week later.

The four-year-old will be joined on a southern campaign by stablemates Someday and Belltone, the past two winners of the Glasshouse Handicap.

Someday clocked the slower time of 50.27s when he won his barrier trial by 1-1/2 lengths from Silver Slipper runner-up Whiskey Allround while Belltone finished fourth in Sizzling's heat.
