0833 AUSTRALIAN OPEN UP FOR GRABS - WAWRINKA

"It's big surprise that they (Andy Murray and Novak Djokovic) not in the draw anymore... It's for sure opening the draw on the other side with Novak not here," Stan Wawrinka said after beating Andreas Seppi.

"It's going to be interesting to see who is going to get there. But you have some big players there. You have Nadal. Roger is playing now against Nishikori. I just think it's interesting tournament."

0814 LESSER MARGIN FOR ERROR AT GRAND SLAMS - MURRAY

"In the slams, with the best-of-five format, you have time to turn things around. There's also time to mess it up as well," Andy Murray said after his surprise loss to Mischa Zverev.

"But, you know, in the best-of-three set matches, it feels like there's less margin for error. If you play a bad set, you're immediately under pressure, whereas in the slams you have time to sort of figure it out and try to turn it around."
