Madison Keys -14- (USA) def Aleksandra Krunic -49- (SRB) | 46 61 62
As to be expected, last year’s Finalist Madison Keys crushed twice as many winners as her opponent on Saturday, but punished herself with twice as many unforced errors.
Serbia’s Aleksandra Krunic started efficiently. She captured the first set after opening the match with a break. In the third, she broke Keys twice more – but unfortunately, failed to protect her own serve in the process.
Turns out, Krunic’s last hold was the only game she put on the board in set-2. Seriously. She lost five consecutive service games, effectively handing the match to Keys.
