Phillip Simmonds had a big week, qualifying for and reaching the finals in the challenger at Sacramento. With those 8 matches played, Simmonds takes the lead with 91 matches played while there is a three way tie for second. Spaniards once again occupy 6 of the top 10 spots.
Absolutely no change until the 10th spot in this category. It looks like Roger Federer may be finished for the year and has likely cemented his spot at the top.
