US has a mess with wild cards this year. Riske isn't in the main draw, and not sure if she will get one. Vandeweghe might need one just for qualies. So my guess Duval, Oudin, Crawford, Gibbs, Rogers, French, Aussie, and one veteran for MD.
You forgot to leave a spot for the 18s champion. Rogers will probably get the wildcard from the ITF tournaments, but otherwise there are only 3 wildcards where the USTA gets to pick.
