				 Twice Wimbledon champion Kvitova, playing in 
				just her second tournament of the year, was 6-1 1-0 up at the 
				Edgbaston Priory Club when her Czech compatriot pulled out. 
				 
				Kvitova is looking in impressive shape after her absence from 
				the sport following a hand injury caused by a knife attack 
				during an attempted robbery at her home in December. 
				 
				Safarova was the latest player to withdraw in the latter stages 
				of the WTA event. 
				 
				On Friday, American Coco Vandeweghe retired with an ankle injury 
				in her quarter-final against Spain's Garbine Muguruza. 
				 
				In another last eight game Australian Ashleigh Barty also had a 
				walkover, with Italian Camila Giorgi retiring with a leg injury 
				in the first set. 
				 
				Kvitova will face the winner of the Saturday's second semi-final 
				between Muguruza and Barty.
