For racing fans, the stars aligned for Curlin, the 2007 Horse of the Year, to return and race at age 4. Now, for just the sixth time since the Eclipse Awards were first handed out in 1971, a runner has repeated as Horse of the Year.

Seattle Slew was a heck of a racehorse. He started only three times at 2 and had just six races prior to winning the 1977 Kentucky Derby (gr. I). He went on to win the Preakness (gr. I) and Belmont (gr. I) Stakes and remains, 31 years later, the only unbeaten horse to win the Triple Crown.
