With Serena into QF, Halep cannot be #1. Sharapova can if
1) she reaches final & Serena falls in QF 2) she wins title, Serena falls on SF.
Really annoyed that all the remaining Americans are on the same half of the draw. I am not sure Serena could take Madison, and Venus/Serena matches are always messy headcases for ha.
