Neil Poznansky (born July 25, 1972) is a retired Canadian thoroughbred racing jockey who in 1996 was the National Champion Apprentice Jockey in the United States as well as the National Champion Apprentice Jockey in Canada.
Mickey Walls did it first in 1991 with the second being Emma-Jayne Wilson in 2005 who is still the only female jockey to accomplish the feat.
Omar Moreno did it in 2010 and Kazushi Kimura in 2019.
[3] Poznansky successfully followed up his championship year until 2001, when his winners and earnings dropped significantly.
Injuries hampered things further and in 2008, he retired from competitive riding to work as an exercise/training rider and was still active in that capacity through 2019.
