Terravista has joined Lankan Rupee at the top of the world's sprinting ranks following his win in the Group One Darley Classic.
Chautauqua, who split the pair in last Saturday's race, was rated just a point below, giving Australia the top three in the category.
The Mick Price-trained Lankan Rupee had topped the sprint listing on his own with a rating of 123 for his dominant wins in the Newmarket Handicap and TJ Smith Stakes earlier in the year.
But the Joe Pride-trained Terravista jumped to 123 in the latest rankings released on Friday after defeating a star studded field in the Darley Classic at Flemington.
The latest edition of the rankings, released by the International Federation of Horseracing Authorities, is for horses which have raced this year up until November 9.
Japanese star Just A Way heads the list on 130 ahead of a European quartet - Australia, Kingman, the Grey Gatsby and Variety Club - all on 126.
