The rematch between record-breaking duo John Isner and Nicolas Mahut is one of the highlights of day two at Wimbledon.
The pair played the longest match in tennis history in 2010, taking place over three days, which American Isner won 6-4 3-6 6-7 (7-9) 7-6 (7-3) 70-68.
This year's first-round tie is the fourth match on Court Three on Tuesday.
Defending women's champion Serena Williams is first on Centre Court against Aravane Rezai, followed by Roger Federer then Novak Djokovic.
Six-time Wimbledon champion Federer plays Mikhail Kukushkin, the world number 61 from Kazakhstan, while in-form Djokovic, the world number two, faces France's Jeremy Chardy, ranked 54th.
Women's world number one Caroline Wozniacki takes on Spain's Arantxa Parra Santonja in the second match on on Court One, following Andy Roddick's match with Andreas Beck which was held over from Monday because of the rain.
Fifth seed Maria Sharapova takes on fellow Russian Anna Chakvetadze, but is yet to be allocated a court and will not start her match until after 1700 BST.
A host of home players are also in action, starting with the all-British clash between Anne Keothavong and Naomi Broady, another to fall victim to the weather, which is first on Court 12.
British number one Elena Baltacha plays Germany's Mona Barthel and Heather Watson faces Mathilde Johansson of France, while 2008 Girls' champion Laura Robson is up against Angelique Kerber and Emily Webley-Smith meets Klara Zakopalova of the Czech Republic.
Three British men are in action looking to join Andy Murray in round two, with Queen's semi-finalist James Ward looking to continue his good form on grass when he takes on 19th seed Michael Llodra of France on Court Two.
Dan Evans is up against German 20th seed Florian Mayer, while Dan Cox, who was trailing Ukraine's Sergiy Stakhovsky 2-6 1-0 when the rain intervened, continues his first round match.
Regardless of how the British players fare, the meeting between Isner and Mahut will make the headlines because of their marathon match 12 months ago.
Their freak 11-hour-and-five-minute encounter on Court 18 enthralled and captivated audiences around the world, as well as completely rewriting tennis's history books in the process.
After play was suspended at 59-59 because of bad light, the pair played another 19 games before Isner, who had been the 23rd seed, eventually broke Frenchman Mahut's serve before holding out for a truly remarkable victory.
Not only did the duo play the longest set and match ever recorded, they also played the most games in a set and a match, registered the most aces in a match and the most aces by a player.
Isner finished with 112 aces and Mahut 103, easily beating the previous record - held by Croatia's Ivo Karlovic - of 78.
The American took world number one Rafael Nadal to five sets in the first round of the French Open last month, eventually losing out 6-4 6-7 (2-7) 6-7 (2-7) 6-2 6-4 to the Spaniard.
The 26-year-old is 46th in the men's rankings, 53 places above Mahut, who lost to Spain's Fernando Verdasco in the second round at Queen's last week.
Mahut, 29, has been in poor form in the Grand Slams, losing in the first round of the French Open and the second at the Australian Open.
Since their marathon encounter 12 months ago, Isner revealed the duo have since become friends.
"Honestly, before Wimbledon, we'd never said one word to each other," he said.
"Now we text each other quite often and I've got to know that he's a really class act and a really good guy."
