LEXINGTON, Ky. - ClassicStar partnership president David Plummer, who bought champion Xtra Heat privately for $1.5 million on Monday, has been on a shopping spree. By his own estimation, Plummer has spent about $20 million for about 20 broodmares at the Fasig-Tipton and Keeneland November sales. The capstone came Tuesday when he spent $4 million to acquire 2000 Kentucky Derby winner Fusaichi Pegasus's full sister Bless, in foal to Storm Cat.
