You don't play an outdoor competition indoor when there's no rain. They're closing the roof now. Probably favours Federer slightly.
Murray playing really well. That early break and winning the 1st set no doubt gave him the world of confidence. Definitely helped that he's been tested on his serve and come through a lot of them. Heartbreaking the way he lost that 2nd set. Federer's making a lot of errors but that's not the reason why Murray was winning up until them last few games. Murray's playing really well. Probably an opportune time for a rain delay for Murray too. He can win this if it keeps going like it has been.
Still....You just can't take the chance. Better safe than sorry.
What? The roof is only there as a last resort. If they take that mentality then they may as well just change it to an all indoor competition. They closed the roof all day earlier in the tournament when it wasn't raining and got slated for it. They haven't done anything wrong. You only close the roof when it's raining and it's absolutely needed.
