Embarrassing tennis moments include Alize Cornet serving to the wrong side of the court and Serena Williams badly misjudging a lob, both of which occurred at the 2015 French Open. Other embarrassing moments include a ball boy tripping behind Maria Sharapova and Roger Federer's incorrect tweet about Lleyton Hewitt.
Cornet served to the right side of the court while her opponent, Mirjana Lucic-Baroni, was on the left. She went on to win the match. Williams laughed off her miss on the lob.
The ball boy tripped over a flower pot at the Italian Open while attempting to grab an umbrella during a break. Federer made the mistake of saying Hewitt was from New Zealand instead of Australia. Hewitt didn't mind, and Federer quickly deleted the tweet.
