He's been struggling with a knee injury for weeks, but I asked this morning a guy who knows Mannarino and he said the injury isn't that bad, to his knowledge. He was training normally prior to the event.
It's hard to know, though, Mannarino can hardly admit he's not able to play, there is a lot of money to earn at this event for him.
Thanks for answering. Even if it's not a serious injury I guess this has to do with the results. I was very impressed with his game when I saw him playing Metz at TV, I couldn't understand these easy scores for his opponents. I hope he gets the AO wildcard.
