Iga Świątek's run hasn't been without controversy, including one call in her quarter-final win over Emma Navarro that left the tennis world scratching their heads.

Iga Świątek booked her place in the semifinals of this year’s Australian Open after thrashing American star Emma Navarro on Tuesday, but the match wasn’t without its controversy.

Not that Iga Swiatek needs the help during her dominant run through the Australian Open so far, but she did get the benefit of a no-call when she failed to reach a ball hit by her opponent Emma Navarro before it bounced twice.
