World number one Rafael Nadal and seven-time winner Roger Federer will look to follow defending champion Andy Murray and top seed Novak Djokovic into the second round of Wimbledon on Tuesday.
Spaniard Nadal will be out to build on his ninth French Open triumph when he takes on Slovakian Martin Klizan in the second match on Centre Court.
"There is no time to enjoy as I would like to enjoy Roland Garros because I am here in Wimbledon, and I really want to try to play well here," Nadal said. "That's my real goal.
"When I finish here, I will have one month at home probably. For sure that's going to be the moment to be happy, going to be the moment to analyse what happened."
Federer - aiming to eclipse Pete Sampras' open era record of men's titles at the All England Club - tackles Paolo Lorenzi of Italy on Court One.
That match will follow the conclusion of the epic clash between Jo-Wilfried Tsonga, the 14th seed, and Austrian Jurgen Melzer.
Frenchman Tsonga was left frustrated on Monday evening. As he prepared to serve for the match at 5-4 in the fifth set, play was called off due to heavy rain.
Earlier on Monday, there had been no such worries for Murray, who booked a place in the second round with a straight-sets win over Belgian David Goffin on a packed Centre Court.
Later in the day, number one seed Djokovic brushed aside Andrey Golubev of Kazakhstan 6-0 6-1 6-4.
The Serbian said: "Coming into Wimbledon with no official matches (on grass), it always gives you an extra reason to get that commitment and focus from the start and try to play as best as you can. That is what I did and I am very, very pleased with my performance overall."
The world number two will next face Radek Stepanek after the Czech knocked out Pablo Cuevas of Uruguay 6-2 6-4 6-4.
Elsewhere, Queen's Club champion Grigor Dimitrov maintained the momentum from his Aegon Championships victory with a 7-6 (7/1) 6-3 6-2 win over American Ryan Harrison.
However, 18th seeded Spaniard Fernando Verdasco lost to Marinko Matosevic of Australia, the 2013 Wimbledon quarter-finalist going down in four.
Other highlights on Tuesday will see the eighth-seeded big-serving Canadian Milos Raonic on Court Two against Matthew Ebden of Australia, while Court Three will see former Wimbledon champion Lleyton Hewitt take on Poland's Michal Przysiezny.
