Emma Raducanu struggled in a testing Indian Wells wind as she was beaten on her first appearance since being targeted by a stalker during a match.
The 22-year-old Briton was unsure if she was going to even play in the California tournament following the incident at the Dubai Championships on 18 February.
A visibly upset Raducanu recoiled behind the umpire's chair after spotting a man who she had reported for what WTA officials described as "exhibiting fixated behaviour".
After deliberating whether to take an extended break from the WTA Tour, Raducanu decided to make the journey to Indian Wells - one of the biggest events outside of the four majors.
