Key to Internet contest: Lock in early at big odds


John Avello, who heads the race and sports operations of Bally's Las Vegas and its adjoining megaresort Paris Las Vegas, last year introduced an Internet fantasy-stable contest for horseplayers. Named the Breeders' Cup Future Book Challenge, it's back again this year. The free contest, at ballysraceandsport.com, began on Aug. 14 and runs through Oct. 20.

In the Challenge, players must pick three runners for each of the eight Breeders' Cup races, which are to be run Oct. 25 at Santa Anita.

There's more to the contest than just picking the Breeders' Cup winners, however. Odds are based on the future book prices at Bally's, and they are locked in - as if you were betting them with real money - at the time of selection. You don't have to make selections for all eight races at the same time, but when you do put together a stable for each race, all three picks must be made together.

As Breeders' Cup hopefuls compete in the summer and fall stakes leading to the championships, future book odds will change. The idea is to choose horses who get to the Breeders' Cup and have a chance to win, but to get them early enough so that the odds are high.

Avello recently released odds for the Breeders' Cup Juvenile and Juvenile Fillies, and now has odds posted on all eight races.

With the Breeders' Cup future bet available throughout the country this weekend, you can compare the bet's parimutuel odds with the fixed-odds version in Nevada.

Here are Avello's opening and current (through Thursday) odds on some of the top contenders for each race:

Juvenile - Chapel Royal, who was to run in Saturday's Hopeful, opened the favorite at 7-1 and holds at that price. Value Play started at 10-1 and has dropped to 7-1.
