At 14 a player can play in up to eight professional tournaments a year, a figure that rises to 10 events at the age of 15, 12 at 16 and 16 at 17. Only when a player reaches the age of 18 is there no limit.
You forgot to list all the tournaments she won in Pee Wee tennis.
NO one cares about her “junior circuit” success.
Ping me when she wins a REAL tournament.
