Grand Slam of Thoroughbred racing

The Grand Slam moniker is typically only available to three-year-old horses, as the Triple Crown and Travers Stakes are limited to that age.

According to international classifications, the Travers is the third-ranked race for American three-year-olds, behind only the Kentucky Derby and Belmont Stakes.

Due to the lack of success in winning the fourth race, the Travers Stakes has been nicknamed the "Graveyard of Champions.

[7] Unlike the Triple Crown races and the Travers Stakes, the Classic is not restricted to any age group and the Breeders' Cup has been hosted by several different tracks throughout its history.

In 2015, American Pharoah won the Triple Crown for the first time since 1978, making him the first horse eligible to compete for this configuration of the Grand Slam.

Before the final race, sportswriter Bob Ehalt of ESPN declared American Pharoah was competing for the "Grand Slam," coining the second configuration of the term which quickly became popular.

[8][9] Pharoah won the Breeders' Cup Classic on October 31, 2015, and is the only horse to win this version of the Grand Slam.

His owners and trainer planned to run him in the 2018 Breeders' Cup Classic, but an injury was discovered in July and Justify was retired from racing.

Sunday Silence beat Easy Goer by two-and-a-half lengths in the Derby, a nose in the Preakness, and a neck in the Breeders' Cup Classic.

These include: Note: Funny Cide competed in the 2003 Triple Crown and Breeders' Cup Classic but withdrew from the Travers due to illness.
