Sheikh Ahmed bin Rashid Al Maktoum's Nahrain (GB) (Selkirk--Bahr {GB}, by Generous {Ire}), who bagged last year's G1 Prix de l'Opera at Longchamp, and was runner-up in the GI Breeders' Cup Filly & Mare Turf at Churchill Downs during a banner sophomore campaign, has been retired to join her breeder Darley's broodmare band. Following those efforts, she opened this term with below-par efforts in Royal Ascot's June 20 G2 Windsor Forest S. and Glorious Goodwood's Aug. 4 G1 Nassau S., but hit the board in the Sept. 9 G2 Blandford S. at the Curragh, before claiming a second top-level prize in the Sept. 29 GI Flower Bowl Invitational at Belmont. The chestnut 4-year-old signed off with a 10th in the Nov. 2 GI Breeders' Cup Filly & Mare Turf at Santa Anita. “Nahrain left us Thursday and will not race on as a 5-year-old,” revealed trainer Roger Varian. “She has been a huge asset to the start of my training career, winning five of her 10 starts including two Group 1s. She has been a pleasure to train and I now hope she has a long and successful career as a broodmare. It is sad to see her go, but she has given us some great days and we now have to work hard to find another one as good.” Nahrain retires with a career record of 10-5-1-1, and earnings of £669,336.
