Starting with Deuel in the first two matches doesn't seem like the best move.
There are requirements in the matches that make it so a player will have to fall into a spot. Every player must play a singles match and Corey is obviously the last American who has not played. I would have to map out the doubles but Corey either could only play in the first doubles match today or at least the second doubles match today, but he would have to be in one of them.
