WTA Top 10 By Birth Year Updated

The WTA Top 10 by Birth Year page has been updated with the rankings data from this past Monday, March 31st, which is the week after Miami.  There really was not much change among the top 100 as usual as since the '13 year end rankings only 11 players have entered and exited the top 100.  '85 added 2 players at the expense of '86 while was some minor shuffling in the younger players.  '87 and '90 continue to lead with 11 and 12 players in the top 100, respectively, while '93 took a step back to 9 players.  Check out the Top 10 by Birth Year page for some more analysis, and I have archive the '13 year end results.

Here is the breakdown of players in the WTA top 100 by birth year:

1970 - 1
1980 - 2
1981 - 2
