Big congratulations to Iva
Even with R3 here she made her best ever junior result (both, in terms of result, and in terms of points gained), but with this QF she made another huge step forward. GA junior tournaments are some of the toughest there are in the calendar and there is just 5 of them, so they're the equivalent of Premier 5 tournaments like Indian Wells on the WTA tour. Now imagine someone ranked 365 reaching the quarters of a tournament like IW from qualies! Sounds quite amazing.
Good luck against Gonzalez, just go out there are do your best, you definately have nothing to lose!
