Winners of the Preakness Stakes can be connected to each other due to the practice of
arranging horse breeding based on their previous success. All of the horses can be traced back to the three foundational sires, with
Godolphin Arabian the ancestor of 7 winners,
Byerley Turk the ancestor of 13 winners, and
Darley Arabian the ancestor of 131 winners, including all winners since 1938. The
Mr Prospector direct sire line has produced the last 5 Preakness Stakes winners.

Eclipse (1764) line) produced 131 Stakes winners (122 colts, 3 geldings, 6 fillies), including all winners from 1938 to present. The main branches of this sire line are: • the
King Fergus (1775) branch (all branched through the
Voltigeur (1847) line), produced 13 winners. His sire line continued primarily through his son
