London - Novak Djokovic and Roger Federer
can take a step closer to a Wimbledon semi-final duel when they battle for
places in the last-16 on Friday.
Defending champion and top seed Djokovic,
bidding for a third successive Wimbledon title and fourth in total, takes on
America's Sam Querrey.
Victory will give the Serb a 31st
successive Grand Slam win taking him level with Rod Laver on the all-time list,
six behind the record set by Don Budge in 1938.
Djokovic has an 8-1 career record over the
28-year-old Querrey who has only reached the fourth round on one occasion, back
in 2010.
Third seed Federer, the seven-time
champion, saw off world number 772 Marcus Willis in the second round and Friday
faces another British player, 91st-ranked Daniel Evans.
Federer is looking to clinch his 150th win
on grass courts.
Evans, 28, hopes to become the first
British man other than Andy Murray to reach the round of 16 at a Grand Slam
since Tim Henman made the semi-finals at the 2004 US Open.
"It's not a day out for me. It's a
good opportunity. I'm taking it seriously," Evans said.
"He's not a normal guy obviously. It
would be stupid to say it's not a special occasion to play him."
Centre Court action gets underway with
Swiss fourth seed Stan Wawrinka taking on former US Open champion Juan Martin
del Potro who is steadily rebuilding his career after a series of wrist
injuries pushed him to the verge of quitting.
Wawrinka is a former French and Australian
Open champion.
The last time two Grand Slam champions met
in the second round at Wimbledon was in 2008, when Marat Safin defeated
Djokovic.
Del Potro last played on Centre Court in
2013 when he lost an epic semi-final to Djokovic.
Defending women's champion Serena Williams,
chasing a seventh Wimbledon title and Open era record-equalling 22nd major,
faces fellow American Christina McHale on Centre Court.
Williams has a 2-0 head-to-head advantage
over McHale, the world number 65, with both wins coming in 2016.
Sister Venus, a five-time champion and the
oldest woman in the draw at 36, is on Court One facing Russia's Darya
Kasatkina.
That comes a day after Williams was exiled
to Court 18, a decision which led to the American to call for more equality
when it came to scheduling.
Also bidding for third round spots on
Friday are Australian 15th seed Nick Kyrgios who faces Dustin Brown of Germany
in a clash between two men who have both defeated Rafael Nadal at Wimbledon in
recent years.
Japanese fifth seed Kei Nishikori meets Russia's Andrey Kuznetsov while two-time women's champion Petra Kvitova takes on Ekaterina Makarova of Russia.
