I think this is because Mona's BH is really good and she doesn't many problems with Aga's inside out FHs. And today she was many times near the net with solid efficiency.Aga vs umpires 2-0 :lol:
Mona has always given Aga trouble.
2012 Canada: Aga won 4-6 6-3 7-6(5)
2015 Beijing: Aga won 4-6 6-1 6-4
