...and here we are four and a half years later. They're both 20 years old now. Pavic has gone as high as #295 in singles (but #415 now) and #54 in doubles (also his current ranking).
Kekez has gone as high as #560 in singles (#592 now). Interestingly, he won this week's Croatia F ($10K):
+ In R2 he beat Ignatik (#278, CH #137) 63 64
+ In the SF he beat Lizariturry (#320) also 63 64
+ In the F he crushed Granollers-Pujol (#228) 61 61
Excellent week for Duje
Second singles title ever and he did it without losing a set, against some tough opposition.
He plays again in Croatia next week. Good luck!
