According to DRF, "'Moonist, the champion aged Quarter Horse of 2015, was euthanized late Tuesday after complications from colic, trainer John Cooper said on Wednesday.'"
My heart-felt condolences to the multi-graded stakes winner's connections and fans. He was the first horse to win four derbies in a single year (2014) at Los Alamitos. He too won ten derbies and four stakes in that, his three year-old campaign. All told, Moonist was a winner in 24 of 34 starts and earned a total $878,468. The fine gelding won four championship titles, as well. Unbeaten in four starts this year, Moonist was rated the nation’s leading older horse. He wore pink. I liked that. May his memory be a blessing.
