Talented three-year-old Sinba will be the new kid on the block in the Randwick Guineas.

Promising three-year-old Sinba, who was a brilliant winner on debut at this track, resumes from a spell in the Sharp Office Benchmark 68 Handicap 1200m at the Newcastle race meeting on Saturday.

A return to two-year-old racing and the addition of blinkers could be the key to Sinba rebounding at Rosehill.
