When she is on her game she suits a fast court, but recently I think her reactions have been slow and so her shots are either rushed or miss-timed, and so I'm saying the faster courts might not help right now because she already looks slow in her positioning and off balance when hitting a standard forehand and such.
I really hope she wins her match tomorrow, and then she can stop playing a mental game and go back to the kind of play that got her to Birmingham final.
Jankovic at her dramatic best will lead, throw the lead away, spot you a massive lead in the third set, decide to come back with some blazing retrieving and backhands, almost comeback, and then hand you the win, possibly with back to back double faults or netted forehands. You have no agency in this match. You might start to wonder if you have free will. Perhaps solipsism is true after all - is it Jankovic's world and you're simply allowed to live exist in it? It's basically existential waterboarding.
