POMONA, Calif. – Jockey Martin Pedroza used 17 racing days during the 2004 Fairplex Park meet to establish the single-season record for wins at the Los Angeles County Fair. Pedroza won 51 races; 2004 was the last year the Fair meet was that long.
The following season, Fairplex reduced the meet to 16 days and in 2009 trimmed again to its current 15-day format. It appeared the meet record of 51 wins would never be topped.
