The large wager was placed within the opening 15 minutes of betting on the four-day pool. Odds on the mutuel field tumbled to 1-9 when the wager was reflected on the odds board, while the prices on the pool's 23 individual horses instantly soared to 99-1.

By the end of the first day's wagering, the field was down to 1-5. Master David, winner of last weekend's Sham Stakes at Santa Anita, was – at 15-1 – the lowest price among individual entries. Others who received action were Lion Heart (19-1), Eurosilver (30-1), and juvenile champion Action This Day and Tapit (both 40-1). A total of $96,706 was registered in the pool as of about 10 p.m. EST.

Action was slow on the first day of Kentucky Oaks Future Wager, with just $4,930 bet. In its second year, this is the first time the Oaks has had more than a single future pool.

Class Above was the early 5-2 favorite (from 20-1 morning line), while Juvenile filly champion Halfbridled was the 3-1 second choice. The mutuel field sits at 5-1. A.P. Adventure (16-1), Ashado (17-1), Miss Coronado (18-1) and La Reina (19-1) also garnered support.

Wagering ends in Pool 1 on Sunday at 6:30 p.m.
