In this matchup between Emma Navarro and Zheng Qinwen, I would prefer to give the advantage to Emma Navarro. Firstly, Navarro is currently playing much better than her opponent. She has been in excellent form on clay courts this season and has been showing great results in her matches. Secondly, Navarro has more experience in competitions and will be able to compete at a high level against Qinwen. She has already showcased her skills in matches at this tournament and continues to perform strongly. Furthermore, Qinwen has not yet shown her best game this season and has not been able to secure victories on clay courts. Their previous encounters also favored Navarro, indicating her superiority in their head-to-head. Taking all these factors into account, my prediction is that Emma Navarro will emerge victorious in this match.
