As a race horse, Masterstroke won group 2 races and finished third in the prestigious Prix de l'Arc de Triomphe. Due to his good own performance on the track he was put to stud in France where he proved successful. Soon his first offspring won group races and he went to England. By now, the stallion’s genetic potential has been recognized and he is widely held in great esteem. Masterstroke’s sire, Monsun is one of few German stallion to obtain global standing in the past years. He performed convincingly on the flat with a track record of 12 wins out of 25 races and total life earnings of 1,067,881 euros. He was awarded the title galloper of the year in 1993.
Masterstroke’s damline also deserves special mention: the Schlenderhan mare family of Asterblüte had already been among the best of the best in German TB breeding and has been made immortal in the recent past through Allegretta/TB. This damline has become extremely popular in TB breeding these past years and has produced some of the best European TB stallions - Galileo, Sea the Stars, Adlerflug, Tertullian, Black Sam Bellamy – in close succession.
