Hello again. Day three and round two is upon us and that means another opportunity to run the rule over world No1 Rafael Nadal, his form and his shonky knees. The Spanish top seed didn’t appear to have any particular adverse reaction on his official return to tennis last time out in a straight set dismantling of Victor Estrella Burgos, but he – and his legs – are set to be tested a little further by today’s opponent, Leonardo Mayer.

The Argentine, ranked 52 in the world, has recent history with Nadal and pushed him to four sets in the second round of last year’s US Open, before the Spaniard went on to lift the trophy at Flushing Meadows – his 16th slam title, no less. That was one of four times this pair have met, and Nadal has won every one of them, but he was at pains earlier this week to say he will not be underestimating his opponent today.

Mayer, for the record, beat Chilean Nicolas Jarry 6-2, 7-6 (7-1), 6-3 to book today’s date with Nadal. A meeting with either Australia’s John Millman or Damir Dzumhur – currently in action on Court No3 – awaits the lucky winner.

The players will be on Rod Laver Arena shortly. In the meantime, flick me an email or tweet with any thoughts on today’s match, this year’s Open, last night’s kerfuffle about grunting or even Rafa’s bold decision to revert back to sleeveless shirts (what everyone is really talking about).
