LEXINGTON, Ky. – John Stewart, who made his first Thoroughbred purchase last year, was among the top-spending buyers at the Keeneland September yearling sale. He has continued to buy through the fall, purchasing a number of yearlings and weanlings who will one day carry his colors. But while scouting young prospects in the draft, so to speak, Stewart, who will soon acquire a farm near Lexington, also wanted a race-ready prospect for the near future.
