FOLLOWED BY A FAN Tennis Channel
Tennis star Emma Raducanu had to pause her match Tuesday ... after she had an emotional breakdown over a fan's alleged disturbing behavior.
The bizarre scene unfolded during the 22-year-old's tilt with Karolina Muchova out at the Dubai Championships.
Raducanu had started off the showdown just fine, but after a few minutes on the court, she called for a timeout, began crying ... and then walked over to the chair ump.
It was not immediately clear what was going on -- the match's announcers were audibly befuddled on the broadcast -- but later in the day, the WTA said in a statement Raducanu had grown concerned over a spectator in the stands.
