World number seven Miki had looked comfortable early on against Briton Marc McCarroll, taking the first set 6-2 but the home player showed his fighting qualities by taking the second 7-6 on a tie-break.

McCarroll then produced some superb tennis in the decider to take it 6-2 and secure a memorable win over his more fancied opponent.

"It's a big win for me as it's the first time I've beaten a top eight player and a player now playing at Grand Slams, so I'm really pleased with today's performance," said McCarroll.

"I made a slow start and maybe gave him a bit too much respect, but I refocused and made a good start to the second set and was able to play my game.

"If I can play my own game I know I can compete against the top 10."

The Briton now faces a daunting task in the quarter-finals as he takes on Miki's compatriot and world number one Shingo Kunieda who has yet to lose a game after cruising to another 6-0, 6-0 win over Italian Luca Arca.

British number one Gordon Reid saw off the challenge of Sweden's Stefan Olsson in similarly comfortable circumstances with a 6-1, 6-0 win to set up a quarter-final meeting with Frenchman Nicolas Piefer who overcame Britain's Alex Jewitt in straight sets.

David Philipson was another home player to come up short as he lost out to two-time British Open winner Maikel Scheffers of The Netherlands.

Sixth seed Scheffers survived a second set comeback by Philipson to come through 6-2, 4-6, 6-4 and set up a meeting with Argentina's Gustavo Fernandez who beat compatriot Exequiel Casco.

Defending champion Joachim Gerard of Belgium will take on world number two Stephane Houdet of France after they defeated Dutchman Tom Egberink and Japan's Takashi Sanada respectively.

World number nine Kruger was the big casualty in the women's singles competition as Japan's Kanako Domori produced a remarkable comeback to advance to the next round with a 3-6, 6-3, 6-4 victory.

That denied Kruger an all-German quarter-final against world number three Sabine Ellerbrock, who beat France's Charlotte Famin also over three sets.

Domori's compatriot and world number one Yui Kamiji secured her passage through with a 6-3, 6-1 win over Columbia's Johana Martinez and will now face South Africa's Kgothatso Montjane, who beat American Elizabeth Williams in straight sets.
