I was at the match.
First set both played well, then Ginepri played a terrible tiebreak. Rain arrived after that. When they came back, Ginepri played one bad game in the middle of the second set, and that was it. Serra was serving surprisingly well.
Ginepri didn't seem injured at all, and Serra was returning well.
That's good to hear.
It was his first match since the US Open, so hopefully he can squeeze out a last couple of seasons without injury before retiring.
