A dozen mares bred to recent California transplant Collected at the start of the 2026 breeding season have checked in foal to the son of City Zip, reported Rancho San Miguel Friday.The group is part of the stallion's inaugural book in the state, which comprises of 90 mares through mid-March–a reportedly higher number than any state-based stallion covered throughout the entire 2025 season.“We are thrilled with the overwhelmingly positive response that Collected has received so far from regional breeders,” said Rancho San Miguel owner Tom Clark. “He is proving popular with mare owners across the board, from our longtime clients to first-time breeders, some of whom have acquired mares specifically for him.”Clark continued, “His early patrons include not only California breeders, but also breeders from surrounding states. These outside mares are now participating in the California breeding program, as a prelude to their Collected foals eventually participating in the California racing program. This is welcome news as our state's Thoroughbred industry battles uphill challenges.”The post First Group of West Coast Mares Confirmed in Foal to Collected appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
