More on Hughes

Hughes is no stranger to calling major finals. She chaired the 2015 Wimbledon final between Garbiñe Muguruza and Serena, marking the sixth time in her career where she has sat in the chair for the ladies' final at the All-England Club.

That would mark the second major final she chaired that year, calling the Australian Open final between Serena and Maria Sharapova. In that final, she gave the American a hindrance call for yelling "Come on" while Sharapova was trying to return the ball. Later that year, she was also the chair umpire for the Fed Cup final between the Czech Republic and Russia.

During the 2016 US Open, Hughes penalized Marcos Baghdatis during his match against Gael Monfils for using his cell phone during a changeover.
