WTA Top 10 by Birth Year Updated

The WTA Top 10 by Birth Year page has been updated with the rankings data from Monday, July 7th, which is the week after Wimbledon.  There was a fair amount of turnover in the top 100 since the week after Miami, with 15 players entering or exiting the top 100.  The early '80s continue to decrease as each year between '81 and '85 had a player drop out of the top 100.  The younger years didn't add as many as usual with only '91, '95, and '97 (Bencic) adding one player each from those born in the '90s.  The big winner was '89 which added 3 players to the top 100, so now there are 4 years with double digit players ('87,'89-'91).  Check out the Top 10 by Birth Year page for some more analysis.
