Angelique Kerber had to wait in the wings because of the rain before handing ex-Eastbourne champion Ekaterina Makarova a 59-minute tennis lesson.
The rising German star, who has made easy work of her passage to the semi-final stage, needed only 59 minutes to impressively brush aside Makarova 6-2, 6-4 to earn a seventh last four berth this term.
Kerber smiled: “This is my first time here, and I’m enjoying my stay. The courts are very good, so I think that’s the best thing I can do before Wimbledon.”
The #5 seed, who was left waiting for more than two hours after Bartoli’s swift victory, breezed past in-form Makarova – the 2010 Devonshire Park champion.
Kerber, tipped to be a world #1, was a set and 3-1 ahead when rain halted their encounter.
Kerber explained: “It wasn’t easy to manage this – you don’t know how long we need to wait until it stops raining. But I’m happy to go out there after the two hour rain delay and win the match.
“It was not easy because you don’t know how long we need to wait, when it’s stopping raining, but I’m happy to manage this and go out there after the more than two hours rain delay and win – it means a lot to be in another semifinal this year.
“It was difficult for me to go out if I was 6-2, 3-1 up and I was a little bit nervous. I just tried to focus on me, tried to make my game plan and to play until the end.
“It’s good for me to have one more match or maybe two more matches before Wimbledon, and this was my goal here.”
