Iga Swiatek is "not proud" of the way she took her frustration in Indian Wells out on a ball boy but has criticised the "standards" she faces in her behaviour as "not healthy".
The world number two was heavily criticised on social media for appearing to hit a ball towards a boy during her semi-final loss to Mirra Andreeva.
A video shows Poland's Swiatek swiping angrily at a ball thrown to her by a ball boy, with the ball landing close to him before bouncing into the stands.
The 23-year-old wrote a lengthy social media post on Monday addressing the incident, as well as the scrutiny of her behaviour and the emotional impact of her one-month doping ban.
