Overview

• For the first time in its 148-year history, Wimbledon has replaced human line judges with an always-on electronic line calling system across all courts.
• The tournament’s pool of around 300 traditional officials has been trimmed to 80 match assistants ready to intervene if the automated system falters.
• Players and former referees praise the system’s precision but note sporadic errors, low-volume calls and the loss of human interaction with match officials.
• Specific glitches included an unprompted “out” call during Madison Keys’s match and several disputed calls by Emma Raducanu on Court 8.
• In the women’s draw, defending champion Barbora Krejčíková and former winner Elena Rybakina have been eliminated while 18-year-old Mirra Andreeva has surged into the last 16.
