Yep, confirmed by OEM: Bally just receiving treatment which, from my terrible vantage point opposite, I couldn't quite make out on what. Pennetta 2-1 2nd set
Long break followed by the first point lost on 1st serve in the set, only for Bally to win the next 4 - and the first 3 on Flavia's serve, with her first serve deserting her. When Flavia finally finds the court with her first serve at 15-40 Bally breaks
