Ack Ack (horse)

Ack Ack (February 24, 1966 – November 7, 1990) was an American Thoroughbred Hall of Fame racehorse. He raced with success at age two to four, scoring wins in the important 1969 Withers Stakes and Arlington Classic. In 1971 at age five, Ack Ack blossomed into the year's most dominant horse. Conditioned by Charlie Whittingham, he won seven straight graded stakes races on both dirt and grass courses at a variety of distances. His performances earned him United States Horse of the Year honors.
