Top-ranked American Jessica Pegula cruised through her second round match at Wimbledon, wasting little time in defeating Cristina Bucsa.

The fourth seed recorded a 6-1 6-4 victory over the Spaniard, hitting five aces and 15 winners in dominant display. However, there was a moment of controversy involving Pegula and the challenge system.

During one of her service games in the match, World No. 4 Pegula hit a serve long. Bucsa managed to return the serve, but Pegula did not attempt to chase the ball as she assumed her service to be a fault.

The line umpire, however, called the serve ‘in,’ thus granting Bucsa the point for her successful return. Jessica Pegula, unhappy with the call, challenged her own serve, which was in fact declared ‘out’ by the Hawkeye.

Pegula did not seem too bothered by the call however, smiling right after the challenge. Furthermore, she took to social media afterwards and reacted to the incident using a laughing emoji.
