TRAINER Chris Waller will wait until after Winx's next run before making a final decision on whether the Australian supermare will cross the globe to compete at Royal Ascot this summer.

The six-year-old extended her winning streak to 23 with a stylish success in the Group One Chipping Norton Stakes at Randwick on Saturday, a victory which also provided Winx with the 16th top-level success of her career, surpassing Black Caviar's record of 15 Australian Group One wins.
