Emma Raducanu battles more injury problems to reach Australian Open third round - The 22-year-old received treatment for a back issue during her 6-3 7-5 victory over Amanda Anisimova

If you look at the world rankings, which have Raducanu at No 61 and Swiatek No 2, you would expect this to be a straightforward result. But with Raducanu up to No 13 in the overall rankings and 19 in the hard-court ones, you might think the match would be a little closer.
