Great Britain's Emma Raducanu was knocked out of the the Dubai Duty Free Tennis Championships by 14th seed Karolina Muchova in a hard-fought second-round showdown.
The 22-year-old fought back from a dreadful start to take the first set to a tie-break, but ultimately went down 7-6 (6) 6-4 to miss out on a last-16 clash with American McCartney Kessler, who had earlier dumped world number three Coco Gauff out of the tournament.
