2/ The 2ond reason I don't like nigh session is because Murray has always played during the day and could have better feeling with such conditions while Roger played only his 1st round when he wasn't still at his best and than was when he offerer some BPs.
the semifinal will be a night-session (start 19.30 local time as well) then it's Murray who actually fairly complains about that, but honestly considering his heaven draw (another injured player in QF) whereas Fed had dangerous opponents (even if Roger the Dodger, who loves ballbashers, has his opinions on that
), and that Tomic was in their half, Murray couldn't have had a night session on Laver arena, the only thing he could have had was a night-session on Hisense or Margaret Court arena, that's what he can fairly wish he had.
But anyway the conditions are specific in the end of this tournament, with colder weather than in the beginning then it will be specific anyway and favourable to Murray.
EDIT : the weather forecast have been corrected and it seems it will be better temperature for the semi than expected (22 celsius in the evening). And Djoko-Ferrer will be played under hot temperature.
It will be windy as well tomorrow for Fed-Tsonga match (and even more for Murray-Chardy, I can imagine the error fest it will be from J้r้my
), which is good for Roger as he likes more playing in the wind than Tsonga.
