The scheduling is further messed up because all the players who are carrying their country's flag in the opening ceremony are being given a Sunday start, as the opening ceremony is likely to finish after midnight.
yes, at least that must explain why Djokovic doesn't play his doubles first round on saturday.
Generally speaking, according to what I saw, they decided the doubles schedule for saturday considering the number of players in each doubles match who played singles and started on saturday, but considering that Djoko-Troicki's match might have been played on saturday : it seems that the fact that he held the flag in the ceremony played a role here.
A few players will play both doubles and singles on saturday though, when there's only one player concerned in the doubles match : Nalbandian, Isner, Ferrer ... and Benneteau who said in an article which someone posted that he wanted to take part in the opening ceremony anyway even if he played on saturday morning : eventually he will play 2 matches on saturday
I also say that because I've seen that Benneteau has become a major "hope" in this tournament for some
On sunday several players will play both singles and doubles ... and even more on monday and tuesday as there will be two doubles rounds these days.
Anyway, let's hope it doesn't rain too much for the scheduling. The latter forecast look a little bit better although there will be some rain during the tournament for sure.
