EMMA RADUCANU will take on five-time grand slam champion Iga Swiatek after battling through more injury problems to beat Amanda Anisimova in the second round of the Australian Open.

The former US Open champion had her preparations for the tournament disrupted by a back spasm and she had treatment for what appeared to be a lower back issue during the second set.

There were five more double faults — a significant improvement on the 15 in her first-round win over Ekaterina Alexandrova — but that did not stop her reaching the last 32 for the first time here thanks to a 6-3 7-5 victory over big-hitting American Anisimova.
