Monopoly man: Aidan O'Brien's domination of the colts' Classic markets is now almost total

Aidan O'Brien added two more Group 1 victories to his record on Sunday after Puerto Rico and Pierre Bonnard produced authoritative performances at Saint-Cloud.

The trainer now has a monopoly in the 2,000 Guineas and Derby markets, with three at the top of the betting in the former and a staggering eight in the latter, but it is not easy to ascertain where they will end up when next year's colts' Classics roll around.

The Criterium International over a mile is known for producing speedier types so it is understandable Puerto Rico has replaced stablemate Albert Einstein at the head of the 2,000 Guineas betting, especially given his speedier stablemate has only been seen over six furlongs, with his last appearance coming in May.
