Second set: Wawrinka 6-7, 1-2 Medvedev* There is always a point, between a player getting injured and them giving up, when they are wildly improvising alternative strategies and it looks like they might actually work. This is where we are at the moment, with Medvedev hitting an unusual number of drop shots (which aren’t really paying off), increasing the power of his forehands and going for broke with his first serve. There are a couple of aces in this game, which he holds to 30, but the question is whether his body will last as long as his tactics. 8.30pm BST
Second set: Wawrinka* 6-7, 1-1 Medvedev Medvedev runs forward for an easy shot, but gets to the ball before he’s decided what to do with it and in the end scoops something pretty sad back towards Wawrinka, which is put away with maximum violence. A hold to love.
