武漢決賽決定誰先搶下新加坡年終的門票 最後是由Kvitova獲勝
"From the beginning my season was really tough. If somebody told me at the
Australian Open that I would win Wimbledon and still be fighting for
Singapore, I'm not sure I would have believed them.
"But I've had a great second part of the season. It all started a little bit
at the French Open, and from there I just kept improving. I think early on I
was expecting too much of myself, and it was really difficult to take the
loss in my first round in Australia, but I kept working hard, and now I'm
here."
因為年初表現不理想，在澳網時根本不覺得自己會贏溫布頓，而且有前進新加坡的機會，
法網後開始慢慢找到狀態，不給自己太大壓力，才打出能夠晉級年終賽的成績。
這也是她連續四年都拿到年終資格
