British number one Johanna Konta’s final tournament before Wimbledon ended in defeat by world number 62 Ons Jabeur in the third round at Eastbourne.
Konta had led by a break in the first set before the Tunisian fought back to win 6-3 6-2.
French Open semi-finalist Konta has failed to transfer this season’s clay-court success on to grass, losing in the Birmingham second round last week.
Konta is the 19th seed for Wimbledon, which starts on Monday.

Konta lets match slip away on greasy court
The start of the match had been delayed by around half an hour because of rain at Eastbourne and, when they came back on, the players had a brief discussion at the net about whether the surface was playable.
Konta wiped her hand on the grass and asked Jabeur what she thought, with the Tunisian shrugging but raising no objection.
The Briton got off to a good start, holding to love in her first service game before breaking for 3-2. But Jabeur broke back in the next game and grew in confidence.
Konta seemed tentative on the surface – as if not quite trusting that the court was dry enough – and she was punished for it by the Tunisian.
The Briton’s serving, which powered her through a clay-court season where she reached two WTA finals and the last four at Roland Garros, was below par – she won 60% of first-serve points and just 29% of second-serve points. That first figure had been well over 80% in recent weeks.
“I think the rain brought me luck and the win,” said Jabeur, who will face Alize Cornet for a place in the semi-finals. Frenchwoman Cornet beat China’s Zhang Shuai 6-2 6-2.
“I like the way I played. I like to make crazy shots. The crowd are very fair. Konta is a great player and has inspired me in the past. I hope the crowd can come with me now.”
