Unsighted since running third to Esitjaab in an all-fillies finish to the Golden Slipper, Sunlight was unextended to win a barrier trial at Morphettville on Thursday.
Trainer Tony McEvoy sent Sunlight out over 1000m in soft conditions and she easily accounted for city winner More Than Exceed.
On Australian Timeform ratings this season, Sunlight is rated equal fourth behind Blue Diamond winner Written By.
She has won five of her seven starts and more than $2 million in stakes and could be given an end-of-season opportunity to advance that record.
McEvoy has earmarked the Listed Lightning Stakes at Morphettville on July 28 as Sunlight's comeback run depending on her recovery from Thursday's trial.
That could put her on a course to clash with emerging Victorian sprinter Nature Strip, a three-year-old with six wins from nine starts since stepping out for the first time in October.
