Aside from the Grand slams im guessing the Ericsson of course, Indian Wells, and warmups to the Grand Slams.
Serena specially should play more warmups for wimby and the French. In the summer I think they should be SMART and not play the same tournaments every year where they are defending champions.<br />They should ALTERNATE so they don't have to defend points and just gain.
For example instead of Venus playing The acura year after year where she keeps winning, after she wins Serena should play it the next year and then Venus should play the E-style etc.
That with some Fall tournaments and our girls should be doing even better in the rankings. I think they should play 15 tournaments minumum.
