American Jack Sock busted up his middle finger in first-round defeat to Sam Groth yesterday, but he is going to solider on in the doubles alongside Vasek Pospisil.

Although I'm not sure that broadcasting your weak point to your opponents is the wisest move.

Real men manicure.

What will Heather Watson do next? Dip her body into an ice bath, perhaps? She will have to shove world number 19 Garbine Muguruza out of the way first. 

Rafael Nadal is spending his day off in the kitchen. He's tweeted to say we're all invited to casa Nadal this evening. My Spanish isn't great, but I think that's what he's saying. Directions and further details to come later, apparently.

Not everyone will be experiencing Wimbledon's heatwave. Puerto Rico's Monica Puig seems content to be flying to Miami after her 5-7 6-3 6-1 defeat by Monica Niculescu. It's currently a pathetic 28C in Miami. Pah. Although, it is only 6am in the party city.
