He's had some weird retirements in the past. I was hoping he's not injured just didn't want to play after being down two breaks in the second set. I have a feeling his shoulder was sore after having to serve so much. He had over 80 service points in a set and a half. That's a lot for that few service games.
this year he retired several times yes, I think Paulo has decided to be very
careful about his body now after what happened to him
