Emma Raducanu defied a shaky finish to get her grass-court season off to a winning start at the Nottingham Open, despite what she called “insane” line calls against her.
Playing her first match since April, having opted to skip the French Open to focus on her fitness, the 21-year-old Briton beat Japan’s Ena Shibahara 6-1 6-4.
Raducanu said she felt like she was “playing two v one” against Shibahara and the umpire Ana Carvalho.
Electronic line-calling technology is not in use at the Nottingham tournament.
Raducanu’s comments come a day after fellow Briton Harriet Dart repeatedly argued with the umpire over what she believed to be incorrect line calls during her defeat by Katie Boulter.
