SCAT Daddy (Johannesburg) was a mile Grade 1 winner at two, Grade 1 Florida Derby winner over nine furlongs at three, and a stallion whose potential long-term impact was only being realised at the time of his death, aged 11.

He was a leading classic sire in Chile, a notable source of eight-to-10-furlong horses in North America, and a popular source of sprint speed in Europe. US Triple Crown winner Justify was among those he left behind, and there was a rush to win breeding access to his sons. Yeomanstown Stud acquired El Kabeir, one of his high-class US milers, and the move has been rewarded with plentiful support and a successful freshman season.
