Lucie Safarova into the quarter-finals after beating Tereza Smitkova 6-0 6-2. She'll face Agnieszka Radwanska or Ekaterina Makarova next.
American John Isner wins yet another tie-break (10-8) to take the first set off Queen's runner-up and Eastbourne champion Feliciano Lopez

Wozniacki has lost the first set against Zahlavova Strycova 6-2, while Isner and Lopez are into a tie-breaker
Lopez a game from the first set against Isner while Wawrinka and Istomin are on serve on No.2 Court
Break point Nishikori - and he takes it! Kei Nishikori, the 10th seed, is through to the last 16, winning the fifth set 6-4.
...only for Nishikori to miss a backhand return on the next serve and it's 30-30.
Back on Court 8, Bolelli goes long with a backhand and it's 15-30...
Yes, Vallverdu stands a lot closer to the net and serves at top speed to get Murray used to the pace and angles he's about to face this afternoon against Kevin Anderson - a giant at 6ft 8in.
Nishikori moves to within a game of clinching the match against Bolelli (albeit that the fifth set is going with serve). He did it in fine style, too, a crushing backhand across court that has the early birds on Court 8 in raptures.
In the battle of the Ovas ova (sorry) on Court 18, Lucie Safarova has broken fellow Czech Tereza Smitkova in the first set to lead 3-0.
Caroline Wozniacki immediately drops her first service game and trails 2-0 to Barbora Zahlavova Strycova.
Nishikori holds, but if that was anything to go by, we could be in for an epic back-and-forth in that fifth set.
Nishikori rallies back from 40-15 down to advantage, only to double fault.
Kei Nishikori and Simone Bolelli had to wait a day and a half to get on with their five-setter on Court 8 - they've picked up in fine form though, with Bolelli smoking a forehand down the line to set up break point.
It also means there were five American women who entered the third round at Wimbledon - none of them progressed.
Which means a change to the first match on Court 12 - it will now be Caroline Wozniacki versus Barbora Zahlavova Strycova.
We might shorten that to "Babs"...
