GREAT BRITAIN'S Jo Konta claimed the biggest scalp of her career by beating world No.8 Ekaterina Makarova at Eastbourne.

Konta, in the tournament on a wildcard, came through 6-2 6-4 at the Devonshire Park grass-court event to reach the third round.

The 24-year-old, who competed for Australia before gaining British citizenship in 2012, is ranked 146th but has been handed a wildcard into Wimbledon which begins next Monday.

British No.1 Heather Watson, meanwhile, progressed after coming from a set down to beat 11th seed Elina Svitolina 3-6 7-5 6-4.

In Wimbledon qualifying, England's Katy Dunne suffered a disqualification scare in her first round victory after hitting a ball at a line judge.

The 20-year-old wildcard double-faulted to go 2-1 down in the second set, having won the first against Ukrainian Anhelina Kalinina, and accidentally hit her spare ball into a line judge.

Play was suspended when the umpire called for a ruling on whether she should be defaulted but after short break a tearful Dunne was allowed to continue.

She lost the next two games and the set but the world number 335 benefited from Kalinina taking a medical time-out for a wrist injury and recovered her composure to win 7-6 (7/2) 3-6 6-2.

"I was 2-1 down and hit a double fault," Dunne told www.wimbledon.com.

"She hit it back, and I practised my third ball. As I hit [it] the line judge walked into it. Obviously it was quite a hard shot as I was going for it.

"I was like 'oh my God', I dropped my racket. I told the umpire I didn't mean to and she said 'I know you didn't but I have to call the supervisors'.

"For three minutes we were sitting there waiting to hear if I could carry on or not."

Fellow Briton Emily Webley-Smith was not so fortunate as she won her first set against American Grace Min but eventually lost 4-6 6-4 6-3 to the 24th seed.

16-year-old Briton Katie Swan, meanwhile, stunned world No.118 Kristina Kucova in a 6-3 6-4 victory.

Swan, who is ranked 866th, defeated the 25-year-old and will now face two-time Wimbledon quarter-finalist Tamira Paszek of Austria in the second qualifying round.

"I was really nervous before I went on court but I needed to relax and play because I had no pressure at all," Swan told the BBC.

"Obviously I was nervous, and got nervous in the last game, but I was really happy with the way I played.

"I was more aggressive than I have previously been and that worked for me today."

Tara Moore won her all-British clash with Gabriella Taylor 6-2 6-1 but there were defeats for Naomi Cavaday, Lucy Brown and Amanda Carreras.

Elswhere, Marcos Baghdatis produced the result of the day at the Aegon Open in Nottingham, knocking out top seed David Ferrer in straight sets.

The 2006 Australian Open finalist, now down at 59 in the world rankings, had not beaten a player in the top 10 for two years but a strong serving performance took him to a 6-2 7-6 (7/4) win over the Spaniard, ranked seventh.

Britain's Aljaz Bedene was beaten 7-6 (7/4) 6-4 by eighth seed Adrian Mannarino.
