On this day: May 7

May 7 features a couple horse-racing legends and the retirement of Grand Prix great Michael Doohan.

1977 – Seattle Slew wins Kentucky Derby

The American thoroughbred won the Triple Crown in 1977, becoming only the tenth horse to so.

The Kentucky Derby was the first race in the Triple Crown tour, which Seattle Slew won by over a length on this day, 39 years ago.

Following another victory at Preakness Stakes, Seattle Slew powered to a history-making title by four lengths in the finale at Belmont Stakes for his ninth win in succession.

1992 – Cordero Jr. calls it quits

Angel Cordero Jr, one of the most celebrated jockeys in the sport, called time on his distinguished career on this day in 1992.

The slight Puerto Rican became the first from his nation to be inducted into the United States’ Racing Hall of Fame.

During his time in the saddle, Cordero Jr. notched up 7057 wins and was just the fourth jockey to record over 6000 career wins.

1999 – Doohan forced to retire

Michael Doohan was one of the most prolific motorcycle riders of his generation, but was forced retire after a crash on May 7.

The Australian went off the track during a very wet qualifying session at the Spanish Grand Prix, breaking his leg in several places. He announced his retirement shortly thereafter.

The Honda rider won five consecutive 500cc World Championships from 1994 to 1998.
