Britain's Andy Murray has been drawn against world number 56 Daniel Gimeno-Traver in the first round of Wimbledon.
Defending champion Rafael Nadal will open play on Centre Court on Monday against American Michael Russell.
John Isner will play Nicolas Mahut in a repeat of last year's record-breaking 11-hour match.
In the women's draw, top seed Caroline Wozniacki plays Arantxa Parra Santonja and reigning champion Serena Williams faces Aravane Rezai.
Serena and Venus Williams, winners between them of nine of the last 11 Wimbledon titles, have been drawn in opposite halves, setting up the possibility of a fifth final between the siblings.
Murray should have few problems with Gimeno-Traver, having beaten him in straight sets on hard court in Valencia two years ago, as well as on clay in a Futures tournament in 2005.
Gimeno-Traver, 25, lists clay as his favourite surface and has won just one match in two previous appearances at the All England Club.
British number two James Ward, a semi-finalist at Queen's Club last week, faces a tough opener against France's 19th seed Michael Llodra, while fellow wildcards Dan Cox and Dan Evans take on Sergiy Stakhovsky and Florian Mayer respectively.
Among the women, British number one Elena Baltacha has been drawn against a qualifier, while Heather Watson meets France's Mathilde Johnansson, Laura Robson plays German Angelique Kerber, and there is an all-British clash between Anne Keothavong and Naomi Broady.
