Venus Williams safely advanced to the second round at Wimbledon with a 7-6 6-4 win over Belgium's Elise Mertens, and gave an emotional press conference after the match.
The American is chasing an eighth Grand Slam title and sixth Wimbledon crown, but her build-up to the tournament has been overshadowed by the news that she is being investigated amid claims she was involved in a car crash which led to the death of a driver.
Having beaten Mertens, she took to the media room at the All-England Club where questions centred around the incident in Florida which happened on June 9.
"Life, you can't prepare for everything. I can prepare for matches and what opponents will throw at you. But I have no idea what tomorrow will bring," she said.
As the questioning continued, she was asked about the crash and responded by saying: "There are no words to describe how devastating. I'm completely speechless." She then began to cry and left the room full of reporters.
Williams will face China's Qiang Wang in the second round.
Meanwhile, two time-champion Petra Kvitova is playing in just her third tournament since recovering from being stabbed at her home and having won the title in Birmingham just over a week ago.
Despite a couple of wobbles, she showed what a force she is on grass by coming through to beat Sweden's Johanna Larsson 6-3 6-4 to advance to the second round.
The Czech is seeded 11th for the Championships and moved through the gears to claim the first set and despite a rally from Larsson in the second set, Kvitova delighted the Centre Court crowd in just her eighth match back.
"I felt the energy from the crowd and it was amazing to be back here at Wimbledon and playing on the beautiful Centre Court," she said.

The surprise Australian Open runner-up went down 3-6 7-5 6-8 to Germany's Carina Witthoeft and she was joined by Italy's 31st seed Roberta Vinci in bowing out at the first stage.
