top wheel

In exacta wagering, a bet that hooks up a horse
the player thinks has the best chance to win a race with every other horse in the race. Let’s say you think the No. 5 horse will win, and you want to be assured of having him on top in your exacta. You would then wheel the No. 5 with every other horse in the race, at a cost per wager of $2. If there are five other horses in the race, wheeling your selection withall five will cost $10.
