Murray was asked about what advice he might give Williams.

"I don't know exactly what happened. I just read kind of more, like, headlines, rather than the whole stories about it. But it's obviously horrific when anything like that happens," he said. "I'm sure it must be tough for her to focus on her tennis just now. But I don't know how you advise someone on that. ... Unless you've been through it, you don't know. You don't know what to do."Williams has not been cited or charged, and police say she was not drunk, on drugs or texting, but that she drove her SUV into the path of a car carrying a married couple. Williams, who owns a home near the crash site, told investigators her light was green when she entered the six-lane intersection but she got stopped midpoint by traffic and didn't see the other car before she crossed their lane.

"I mean, obviously, I think it would weigh on any human being, and Venus is no different," said Williams' coach, David Witt. "Venus is the nicest person, and (this is) just some random thing that could happen to anybody, any day. But she's looking to focus on the tennis. I'm sure it's weighing on her but we're going day by day and getting good practice in. Once she enters the court, I think her mind's on the match and tennis and winning here at Wimbledon."Asked Monday how difficult the recent weeks have been, Williams replied: "Tennis is still the love of my life. You know, it gives me joy."She is a former No. 1 and the owner of seven major singles titles, along with 14 Grand Slam doubles titles, all won with her younger sister, Serena.

Against Mertens, whom she beat 6-3, 6-1 on red clay at the French Open last month, Williams played unevenly.

She took a 3-0 lead, then let that evaporate. She led 6-3 in the tiebreaker, then needed five set points to close it. She fell behind 2-0 in the second set, then took five of the next six games. She failed to convert two match points at 5-3, before a 33-minute rain delay. She needed three more match points to finally end the first match of her 20th Wimbledon appearance.
