Djokovic reaches Queens semi-finals while Federer on track to retain world No 1 spot as he reaches last four at Halle
Novak Djokovic and Roger Federer triumph and Andy Murray signs up for Eastbourne: ATP round-up
Novak Djokovic joined the 800-win club as the former world No 1 moved into the Queen's Club semi-finals with a 7-5, 6-1 victory over Adrian Mannarino on Friday.
Djokovic took just 78 minutes to crush Mannarino at the Wimbledon warm-up event, in the process becoming the 10th player in the Open era to reach 800 match wins.
The 31-year-old will play France's Jeremy Chardy or American youngster Frances Tiafoe in the last four as he bids for his second Queen's final appearance.
If Djokovic wins the semi-final and goes onto take the Queen's title for the first time, he will pass Stefan Edberg into ninth place on the all-time wins list.
Meanwhile, Roger Federer stepped up his grass game as the start of Wimbledon looms, holding off Australian Matt Ebden 7-6, 7-5 in their quarter-final at the ATP Halle tournament on Friday.
With his world No 1 ranking on the line, the Swiss is sparing no effort to make sure he lifts a tenth title at the event on Sunday.
Failure to win the grass title would send rival Rafael Nadal back to the top spot.
"I felt I had to push myself today," Federer said. "It didn't come as easy as it did in other matches. But you can't allow that to be frustrating. I can take away a lot of positives.
"Now that I'm in the semi-finals I can see the light at the end of the tunnel; you either lose in the semis or have two more matches max. That allows me to find extra energy.
"I'm happy I played well when I had to. I'm happy I got through somehow."
Elsewhere, former world No 1 Andy Murray is to take his decision over whether or not to play at Wimbledon to the wire after accepting a wild card to play at the Eastbourne ATP event next week.
The 31-year-old Scot - a two-time Wimbledon champion - will hope to get enough encouragement at Eastbourne after losing his first competitive match in 11 months earlier this week on the grass of Queen's to Australian Nick Kyrgios.
Murray had not played competitively since a Wimbledon quarter-final defeat against Sam Querrey last year as he was beset by a hip problem which eventually required surgery in Australia in January.
Murray, whose ranking has plummeted to 156 in the world, is so keen to test his match fitness he will be playing at the Eastbourne tournament for the first time since 2006.
"I'm looking forward to getting some more time on the grass courts at Eastbourne this week," said Murray.
"I played Davis Cup there in 2010 and I know the courts and facilities there are excellent.
"It was good to get back to competition at Queen's this week, and I'm hoping to building on that next week at Devonshire Park."
