She’s been called the best racehorse in world time and time again but it’s taken a lot more than popular opinion in Australia to convince the judges of the World Thoroughbred Rankings.

While Black Caviar does stand atop of the rankings she’s not alone, joined by English three-year-old Frankel which is also unbeaten.

While his streak is nowhere near as extensive as hers it was a six lengths win in the Group One 2000 Guineas at the end of April which  saw him jump up to equal first.

They both sit on a rating of 130 in the second release of figures for 2011 by the International Federation of Horse Authorities which takes into account runs from December 1st last year up until May 23rd of this year.

After making his debut in Europe So You Think also managed to jump up the list and he’s now in outright third on 126, four points behind the leaders.

While he’s now based in Ireland for Aidan O’Brien, the former Bart Cummings star gives Australia and impressive dominance at the top of the list.

He’s already claimed the Group 3 Mooresbridge Stakes and the Group 1 Gold Cup and he could even meet  Frankel in the upcoming Sussex Stakes.

If he could beat him there it would surely mean Australian horses would go one – two at the summit of the world rankings.

Black Caviar has already broken just about every record in Australia and her current world rating set a new benchmark as well.

“Black Caviar’s rating of 130 remains the highest by an Australian horse since the World Thoroughbred Rankings started in 2002 and she is still the only sprinter ever to head the list of the world’s top 50 racehorses,” Greg Carpenter, chairman of the ANZ Classifications committee and Australia’s representative on the World Thoroughbred Rankings committee, said.

Black Caviar won’t be adding to her rating anytime soon though as she’s currently spelling ahead of a return in the Melbourne Spring Racing Carnival.

She’s currently won 13 in a row and a win first up upon her return would equal the mark set by the immortal Phar Lap.

Last weekend Rocket Man made headlines after storming to victory in the Kris Flyer International and handing down a challenge to the rest of the world.

He did move up in the ratings but only to equal fourth with Canford Cliffs on 125.

The big mover though was Hay List which has received some reward after finishing second to Black Caviar every time they’ve met.

He was 30th in the ratings but he’s now moved up to equal seventh and is among good company including JJ The Jet Plane from South Africa and Japan’s Dubai World Cup winner Victoire Pisa.

Hay List grabbed the 122 ranting with his All Aged Stakes win and he also was looked on favourably after a closer second placing in the BTC Cup.

Fellow Aussie More Joyous also found her way into the top 50 after her win in the Group 1 Queen Of The Turf stakes at Rosehill in April.

She received a rating of 120 which is only one point behind the French mare Sarafina, and the only mare ahead of them is Black Caviar herself.

There are three other Australian horses good enough to feature in the top 50, Mick Price’s Heart of Dreams on 118 and the Mark Kavanagh duo of Shocking on 119 and Whobegotyou on 120.
