Roger Federer and Serena Williams are both back on Centre Court at Wimbledon on Wednesday as they look to advance to the third round.
Play is under way on Day 3 at Wimbledon, with former finalist Milos Raonic of Canada among the early starters as the second round begins at the All England Club.
The 13th-seeded Raonic was playing John Millman of Australia as he bids to reach the third round for a sixth straight year. He lost the 2016 final to Andy Murray and reached the quarterfinals last year.
Number 10 Madison Keys of the United States was the highest-seeded woman in early action, playing Luksika Kumkhum of Thailand.
Federer will play Lukas Lacko of Slovakia as he continues his quest for a record-extending ninth title at the All England Club.
Williams then faces Bulgarian qualifier Viktoriya Tomova as she goes for a 16th straight match win at the tournament — having missed last year while pregnant.
Australian Open champion Caroline Wozniacki and last year's men's runner-up, Marin Cilic, are also back in action as they try to avoid more upsets at the tournament.
Three of the top-10 seeded men lost in the first round, while former champions Maria Sharapova and Petra Kvitova also went out on Tuesday.
The forecast calls for more sunny skies, although there is a 30 percent chance of rain showers in the afternoon.
