Overview

• Alexander Zverev received a warning for unsportsmanlike conduct after photographing a disputed ball mark during his Madrid Open match against Alejandro Davidovich Fokina.
• The German player criticized the electronic line-calling system, claiming the technology made a significant error in ruling a ball in during the second set.
• Zverev later posted the photo on Instagram, drawing attention to the controversy and prompting additional commentary from players like Donna Vekic and Victoria Azarenka.
• This incident follows a similar warning issued to Aryna Sabalenka earlier this month, as players continue to express concerns about the reliability of the system on clay courts.
• The French Open remains the only clay tournament this season to retain traditional line judges, contrasting with the ATP and WTA's broader adoption of automated systems.
