Bettors from across North America wagered more than $1.5 million on the May 11 $500,000 Lone Star Derby (Gr. III), which crushed the single race wagering record for the 5-year-old Grand Prairie, Texas, racetrack.

A total of $1,362,500 was bet into Lone Star Park's commingled pool and another $143,435 was bet into a separate pool at Calder Race Course in South Florida for a total of $1,505,935. That figure does not include money wagered in a separate Canadian pool, which will be made available Sunday.

The previous Lone Star Park single-race high was $1,317,711 on Lone Star Derby Day in 2000.

Wagering on Lone Star Park's 11-race program by on- and off-track patrons totaled $4,667,929 - a giant 23% gain from the $3,794,674 bet on Lone Star Derby Day a year ago. A total of $926,641 was bet on-track by the 10,043 in attendance and another $3,741,288 was wagered at more than 700 simulcast outlets nationwide.

Kentucky invader Wiseman's Ferry won the 1 1/8-mile Lone Star Derby in gate-to-wire fashion by 2 ¾ lengths in 1:49.92 - a stakes record. Jorge Chavez rode the winner for trainer Niall O'Callaghan and owners Morton Fink and Lee Sacks of Chicago and Don and Dana Meyers of Indiana.
