HE RETIRED !!!!
I didn't understand...I was watching the match, Seb didn't seem to be bad, and at the end of the second set, -that he lost- he asked to the kiné to come on the court, they chated, then he stoped !
He is not injured, but I think (as the commentators at tv) he is just very tired after his tournament and his travel in Japan, so he probably prefered not taking risks to injure himself , when he plays forcing, he injures himself, so it's just a precaution I guess (I hope !), Seb is very attentive with his body.
It means he withdraws in double with Arnaud. Sniff !
