Peak Goatber this year:
Vs Wozniacki (Stuttgart): amazing display of tennis on rather fast clay + serve working well (unexpected)
Vs Azarenka (YEC Sofia): great display of very active counterpunching + serve working better than usual + great mentality.
Vs Bartoli (Open GDF Suez): she wasn't at her best but she played very well, particularly good for the transition of game defense from offense.
Vs Wozniacki (Pekin): Great first set (like in Stuttgart), good offensive game, Wozniacki improved her level during the match, Kerber's level dropped a bit in the second but she managed to raise her game again and finally outlasted her (unusual as it's one of Wozniacki's strengths).
