Murray ruptured ligaments at last month’s Miami Open.
Raducanu has won four matches in a row and now faces Swiatek for a place in the Stuttgart semi-finals
The 21-year-old declared at the start of the week that she was playing the best tennis of her career and swatted aside Linda Noskova 6-0, 7-5. The real test to her claim comes later on Friday afternoon when she faces the world No1 Iga Swiatek for a place in the semi-finals. Noskova is no slouch having knocked out Swiatek herself in one of the early shocks at this year’s Australian Open but Raducanu was a class apart from the outset.
