Re: Donna Vekic
Since Donna is 16 now, she can play 12 professional tennis tournaments + WTA Tour Championship(if she qualifies)+ Fed cup(any level of competition).
She may receive also a maximum of four(4) WC into any WTA Tour Tournament and/or ITF Women's Circuit events, provided, however, that she dosn't exceeds the WTA Tour and/or Women's Circuit maximum calendar year limits for singles or doubles, Main Draw or Qualifying WC.
So there is plenty of room to play tournaments without juniors tournaments.
She can play 12 tournaments + qualifiers + fed cup...
