1847: Hey, where do you think you're going? The players are heading back out onto a sunbathed stadium court. Honest.

1838: And the players troop off as the rain gets heavier. I expected more from Toronto, I really did. Stay tuned...

1836: The players are out on court, Federer sticking with the pink number that has divided opinion all week while Murray is in his regular white and blue. The bad news is... umbrellas are going up, so the two men sit in their courtside chairs and wait while ground staff drag towels along the lines with their feet. There has to be a better way.

5 live's David Law on Twitter: "Sky clearing, sun out. Hot. Will be horrible conditions to play in tough. Novak Djokovic would not like this at all. Too humid."

1830: Murray leads their head-to-head 6-5 but Federer has won the last three and definitely gave the impression after Australia that he thought he'd worked the Scot out. Still, Murray has been playing with a bit more freedom in the last week, hitting through his forehand on a more regular basis, and his ability to retrieve lost causes can make opponents go for too much. Federer v Murray is usually attack v counter-attack, but the Briton might try and take the initiative a little more today.

1825: Good Evening. It's been a while since we've seen Andy Murray take on Roger Federer, seven months in fact, but their last meeting had lasting effects for the Briton. Defeat in the Australian Open final plunged Murray into a gloom that he didn't emerge from until Wimbledon. Since then he's sacked his coach, reached the final in LA and beaten Rafael Nadal on his way to today's final. This is hard courts though, and on hard courts Federer remains the man to beat.
