Emma Raducanu lost to Karolina Muchova on Tuesday after an emotional first set in which a male spectator -- who according to the WTA "exhibited fixated behavior" in a public space the day prior -- was ejected at the Dubai Championships.

Emma Raducanu mysteriously broke down in tears as she slipped to a second-round defeat against Karolina Muchova at the Dubai Championships.

Raducanu positioned herself behind the umpire's chair and there were no microphones to pick up what was said, though Muchova sensed that her opponent was struggling and consoled her as the Briton dabbed her eyes with a towel.
