Melbourne: Andy Murray is aware that the ATP Tour is not pleased about the decision to add an extra day of play at the US Open – a Monday men's final – without also increasing compensation for the players.

But he says he hasn't heard of any plans for a reported boycott of the event. “Since the player meeting, I haven't discussed with any of the players what was said there, what the plans are,” Murray said Monday after his fourth-round win over Gilles Simon at the Australian Open.
 
“But I know that the ATP are not particularly happy with the Monday final. I know that's an issue because however much revenue they make from having an extra day on their tournament hasn't really reflected in the increase in the prize money.”

He said the players have been advocating for increased prize money, but not with an additional day of play. “I think that's what they're disappointed with,” said Murray, who won his only Grand Slam at the 2012 U.S. Open.

“But I personally haven't spoken with anyone about boycotting the event. I don't want to go into that here at all, not the place for it,” he added. “Got the second week of a Slam to focus on. Can discuss that after the event.”
 
Last year, organizers of the Australian Open were also faced with the threat of a player strike, in part due to discontent over how prize money was distributed at the majors. The Australian Open responded by taking the lead among Grand Slams in increasing prize money this year, making it the richest tournament.

Tweeting with the enemy
 
It was 4 a.m. on Monday, about two hours after Novak Djokovic had ripped off his shirt to celebrate his thrilling five-set win over Stanislas Wawrinka in the Australian Open.

But before turning in, Djokovic fired off one last tweet. It was to his opponent. “Stan, thank you very much!! I am sorry for your loss.. Wish you all the best for the rest of the season.. It was great pleasure,” Djokovic wrote.
 
Still awake himself, Wawrinka replied four minutes later: “Congrats for the fight tonight! Good luck for the rest of the tournament.”

Then the 27-year-old Swiss player tweeted another message in French: “Ça fait mal... Très mal ........”, or “That hurts.... Really hurts.” Djokovic next faces No. 5 Tomas Berdych in the quarterfinals.
