Misa is on the EL for 50k Sacramento in the week of 7 July and she is into the MD already, great choice
She has said in an interview that she is also gonna play 2 WTA tournaments after Wimbledon so I guess those could be some in the American hardcourt season? Presumably the slightly weaker tournament in Washington and another one. Besides that, the following weeks there is 50k Carson and 50k Lexington which she could play as well.
So then her schedule could be something like:
07.07.14 50k Sacramento, CA (signed up for 25k Gatineau, Canada with priority 2)
14.07.14 50k Carson, CA
21.07.14 50k Lexington, KY (wouldn't be surprised if she ended up skipping this one)
28.07.14 WTA Washington (100k Vancouver is also in this week)
She has 30 points to defend from 75k Beijing and 22 points from WTA Suzhou. Some significant results will be needed to maintain her ranking. Since the USO Q has a high cut-off she will probably get in if she does reasonably well providing her ranking doesn't slip too much.
