Seventh Heaven led an Aidan O’Brien-trained sweep of the top two placings Thursday in the Group 1 Yorkshire Oaks at York Racecourse, beating her favored stablemate, Found, by 2 3/4 lengths. Queen’s Trust finished third, and another O’Brien-trained filly, Pretty Perfect, was fourth, and none of these fillies is even rated the top female in the O’Brien stable, a position presently occupied by Minding.
