Johanna Konta has powered through to the last 16 at Wimbledon.

The British No.1 from Eastbourne beat Greece's Maria Sakkari 6-4, 6-1 in 76 minutes in humid conditions on court one today.

World No. 7 Konta, the favourite for the title with bookmakers following the exit of Karolina Pliskova last night, was too strong for her 101-ranked rival.

She took an early grip with a break in the first game, then her formidable serve rescued her when Sakkari forced two break points for the chance to level at 4-4.

Konta, the last British hope following Heather Watson's earlier three-set defeat on centre court by Victoria Azarenka, clinched the first set in authoritative fashion in 39 minutes.

The sixth seed, watched by 1969 British Wimbledon champion Ann Jones, started the second set like the first, capitalising on her third break point in an opening game spanning 12 minutes when Sakkari hit a backhand long.

Another break, prompted by a ferocious forehand winner and secured when Sakkari tamely netted a forehand volley, effectively extinguished any threat of her 21-year-old opponent from Athens mounting a revival.

The last hope for Sakkari, in the care of Andy Murray's ex-coach Mark Petchey, evaporated with an overhit forehand which would have reduced her deficit to 4-2.

Konta now faces Caroline Garcia in the fourth round on Monday for a place in the quarter-finals.

The 22-ranked French 21st seed defeated Petra Kvitova's conqueror Madison Brengle in straight sets.

The last British player to reach the quarter-finals was Jo Durie in 1984.
