In addition to Lemberg, he sired three other winners of The Derby and through his grandson, Phalaris, he is the direct male-line ancestor of most modern thoroughbreds.

He returned to his best form in autumn at Newmarket, winning another Rous Memorial Stakes over five furlongs by a neck from the filly Yellow Slave, to whom he was giving seven pounds.

At the same course he then took the Middle Park Stakes giving three pounds to the future American champion Whisk Broom and winning by a neck.

[6] At the same course two weeks later he again defeated Whisk Broom, this time by five lengths, in the Dewhurst Stakes,[7] and went into the winter break as favourite for the following season's classics.

At Epsom he started 7/4 favourite in front of a crowd estimated at 250,000, many dressed in black as a mark of respect to the recently deceased King Edward VII.

Lemberg beat a supposedly "moderate lot"[13] by three lengths to win the St James's Palace Stakes at Royal Ascot, with Swynford, among the beaten horses.

[15] Lemberg was reported to be working poorly[16] before the St Leger and finished third, beaten a head and one and a half lengths by Swynford and Bronzino.

He then started odds-on favourite, but was beaten by Swynford in the Princess of Wales's Stakes at Newmarket, when attempting to give five pounds to his rival.

He was then asked to give two stones in weight to the top-class three-year-old Stedfast in the Jockey Club Stakes[24] at Newmarket and finished second, beaten four lengths.

Late in the year he won the Champion Stakes for the second time in anticlimactic fashion; he was allowed a walkover when no other horses opposed him.
