IN last week’s column I wrote about the success of Deep Impact and his influence on the breeding industry in Japan and globally. Seven days later and I have occasion to write about his full-brother Black Tide, sire of the recent Group 1 Japan Cup winner Kitasan Black.

Unraced at two, Kitasan Black, a son of Sunday Silence, has been a model of consistency over the last two years and his latest top-level victory is his third in Group 1 company. Last year he landed the Japanese St Leger and was placed in their 2000 Guineas. This year he has added the Group 1 Tenno Sho Spring to his tally of victories and he has only been out of the first three once in 13 starts. Kitasan Black has done something his sire failed to do – win at Group 1 level.
