The winner of the 2005 Triple Crown in Uruguay, he was later purchased by Sheik Hamdan bin Rashid Al Maktoum, who paid approximately US$1.4 million for the horse.

Quendom and Invasor's maternal line are at Haras Santa Ines, Duggan, Province of Buenos Aires, Argentina.

Invasor won the first leg of the Uruguayan Triple Crown, the one mile Gran Premio Polla de Potrillos run on September 10, by 5¾ lengths under heavy rain on a muddy track.

[4] Invasor was sold after winning the Uruguayan Triple Crown to Sheik Hamdan bin Rashid Al Maktoum, who paid around US $1,400,000 to have the horse run for Shadwell Stable.

On 6 August, he won his third straight Grade I race, holding off a hard-charging Sun King to win a photo finish in the Whitney Handicap at Saratoga.

"In Uruguay, soccer is our main sport," said Luis Costa Baleta, a horse owner from a long-time Uruguayan racing family.

"[3] The racing journalist and writer Miguel Aguirre Bayley wrote: "In my opinion, Invasor excelled because of his refined qualities, his endurance, and his outstanding intelligence.

"[5] On November 4, 2006, Invasor, ridden by Fernando Jara, won the $5 million Breeders' Cup Classic at Churchill Downs, Kentucky.

The field included favored Bernardini, second favorite Lava Man, and European three-year-old champion George Washington.

Coming into the stretch, Invasor and Jara found the hole they needed and squeezed through, achieving a two length victory over Hesanoldsalt, ridden by Rafael Bejarano.

On March 31, 2007, Invasor, again ridden by Fernando Jara, took the $6 million Dubai World Cup in the United Arab Emirates against his rival Discreet Cat.

Discreet Cat finished last by 23 lengths, but Premium Tap, who had set the pace, battled Invasor in the stretch for place with the Hong Kong horse Bullish Luck third.

In the one race that he lost, the UAE Derby, he finished fourth behind Discreet Cat, a loss Invasor avenged in the running of the 2007 Dubai World Cup.

"There has been tremendous interest from South American breeders to have access to Invasor from the day he retired and we are pleased now to offer them this opportunity with his return to the country where he started his incredible racing career," said Kent Barnes, Shadwell Farm stallion manager.
