Champion raccemare Stellar Wind will be retired and bred to Triple Crown winner American Pharoah after selling for $6 million to Coolmore’s M.V. Magnier at the Keeneland November Breeding Stock Sale on Tuesday.

The $6 million paid for Stellar Wind is the co-second-highest-price ever paid for a broodmare prospect at Keeneland, equaling the amount paid for champion Take Charge Brandi at the 2015 November Sale.
