Nahrain remained unbeaten after four races, and earned a fees-paid berth to the Breeders' Cup Filly and Mare Turf next month, with a nose victory in the Group 1 Prix de l'Opera at Longchamp Racecourse in Paris on Sunday.
Premier Pegasus will earn respect grudgingly. He remained unbeaten after three races with a front-running win in Saturday's $100,000 Hollywood Prevue Stakes, but was not favored despite a stakes win over this track last month.
Zenyatta worked six furlongs in 1:13.80 on Saturday at Hollywood Park, the final workout before the 6-year-old mare will seek to extend her unbeaten streak to 19 races in the $250,000 Lady's Secret Stakes next Saturday.
Twirling Candy stretched his unbeaten streak to three with a victory in his stakes debut in the $112,500 Oceanside Stakes on Wednesday's opening day at Del Mar. The winning margin was 2 1/4 lengths over Macias, and it did not seem that close.
Sunday evening, several hours after Zenyatta caught a game St Trinians in deep stretch of the $250,000 Vanity Handicap to extend her unbeaten streak to 17, trainer Mike Mitchell sent John Shirreffs a text message.
