Old Man's sire Orbit was bred by the Duke of Westminster and won the Eclipse Stakes and Craven Stakes in Great Britain before being exported to Argentina in 1889, where he stood at stud and became an extremely successful sire.

As a two-year-old, Old Man was sold to Caballeriza Petite Ecurie, owned by Adolfo and Rufino Luro,[3] at a price of m$n8,000.

[13] Old Man had a minor illness prior to his next start, in the Premio Eliseo Ramírez, run over 1400 meters.

Once again, he made up ground on the backstretch, and in the homestretch he caught the leaders and drew away to win by three lengths.

[16] The second leg of the Triple Crown, the Gran Premio Jockey Club, attracted a higher class of competition than Old Man had faced previously.

Jockey Estévez kept Old Man near Dévil, not letting him gain too large of an advantage in the early race.

Before the homestretch, Old Man took over the lead from Dévil, and easily won the race, tying the time set by Pippermint, at that point the only winner of the Argentine Quadruple Crown.

[17] Old Man's next race was the Gran Premio Nacional, the final leg of the Argentine Triple Crown, run over a distance of 2500 meters.

Only 5 of the 33 horses nominated to the race dared face Old Man, who attracted 24,083 of the 32,150 win tickets sold.

After the start, Old Man settled into third, beind Cleso and Acero and in fornt of Padilla and Pretendiente.

Old Man pulled back ahead near the end of the race to win by a half length.

Around the final turn, Estévez pushed Old Man forward, and he entered the straight a couple lengths ahead of Calepino.

[3] Old Man was retired to stand stud at Haras El Moro, also owned by the Luro family.

That year, they won 20 races and m$n218,778,[1] placing him fourth on the general sire list in Argentina.

[7] In 1913, Old Man was the leading the sire in the world, per the Bloodstock Breeders' Review, beating out other sires such as Simonian, Cyllene, Desmond, St. Frusquin, Chaucer, Rock Sand, William the Third, Gallinule, Spearmint, and Sundridge.

[1] Old Man led the Argentine broodmare sire list nine times, 1920 and 1922–1929, as well as finishing second in 1921, 1934, and 1935, third in 1933, and fourth in 1932.
