Hard to tell. Probably a bit stiff and sore, needed the massage. But she served 3 aces in a row to save a break point, and has just broken serve herself
*2-2
Looking at the live rankings, it appears that, apart from Aga who is a way behind, everyone near Jo on the leaderboard is out now, so her ranking post-tournament is in her own hands.
Or rather Venus' hands. 2-3* after another break
