Five Wimbledon facts - day six

London: Five facts on the sixth day of Wimbledon at the All England Club on Saturday:

- Roger Federer will look to extend his 18-match winning streak against Australian opponents at Grand Slams when he takes on Sam Groth. The seven-time Wimbledon winner has only lost to an Australian opponent once at a major -- to Pat Rafter at 1999 Roland Garros.

- 2013 champion Andy Murray will need to overcome Italian Andreas Seppi if he is to reach the round of 16 for the ninth time. The Italian will hope to record his third career victory over a top three ranked opponent and book his spot in the round of 16 at a major for the fifth time.

- Qualifiers Nikoloz Basilashvili, who takes on Roberto Bautista Agut, and Dustin Brown, who faces Viktor Troicki, will hope to take their dream Wimbledon runs into the second week. It is the first time since 2012 that multiple qualifiers have reached the third round. Brown knocked out Rafael Nadal in the second round.

- Former Wimbledon finalist Tomas Berdych will have reason to be confident ahead of his round match with Pablo Andujar. The Spaniard had only won one match on grass at any level -- at Wimbledon qualifying in 2007 -- in his career prior to coming to Wimbledon this year. He had to play back-to-back five-set matches to book his place in the third round.

- Davis Cup teammates Gilles Simon and Gael Monfils will have to put their national allegiance aside when they meet in the third all-French clash of the tournament. The pair have never met on grass, and Monfils will be looking to defeat Simon for just the second time in seven attempts.
