Players banned for doping should not receive wildcards on their return, says Caroline Wozniacki, after Simona Halep was beaten on her comeback in Miami.
Two-time major champion Halep, lost 1-6, 6-4, 6-3 to Paula Badosa in her first match since a four-year doping ban – later reduced to nine months.
Halep was given a wildcard for Miami but Wozniacki said such players “should work their way from the bottom”.
