British number one Heather Watson will resume her first-round match with Caroline Garcia at Wimbledon on 30 June level at one set all after play was suspended due to bad light.
Having been initially brushed aside 1-6 with worrying ease, Watson took the second 6-3 but the decision was made to stop the contest before the deciding set got underway.
Elsewhere on day one at the All-England club, wildcard Liam Broady won his first ever grand slam match against Marinko Matosevic.
Broady, whose sister Naomi lost to Mariana Duque-Marino, trailed by two sets to love but showed great resilience and belief to battle back and win 5-7, 4-6, 6-3, 6-2, 6-3 in just over three hours.
Defending champion Novak Djokovic is also through to round two after beating Philipp Kohlschreiber in straight sets, while Serena Williams progressed with a 6-4, 6-1 win over Russia's Margarita Gasparyan. Sister Venus inflicted a double bagel on fellow American Madison Brengle.
There was to be no great shock on centre court as Britain's Johanna Konta lost 6-2, 6-2 to 2004 winner Maria Sharapova. Ana Ivanovic defeated Xu Yifan and Victoria Azarenka cruised past Anett Kontaveit. Sloane Stephens is in the draw for round two with a 6-4, 6-2 win over Barbora Strycova.
Stan Wawrinka, winner over Djokovic at the French Open earlier in June, triumphed 6-2, 7-5, 7-6 against Joao Sousa but 19th seed Tommy Robredo fell in three sets to John Millman.
Kei Nishikori beat Simone Bolelli in four, Marin Cilic saw off the challenge of Hiroki Moriya and Milos Raonic advanced against Daniel Gimeno-Traver.
Former champion Lleyton Hewitt's final Wimbledon appearance ended in an early defeat, however, with the veteran Australian beaten 3-6, 6-3, 4-6, 6-0, 11-9 by Jarkko Nieminen.
There were also wins for Grigor Dimitrov, John Isner and Kevin Anderson. Andy Murray, Roger Federer, Rafael Nadal and Petra Kvitova are all in action tomorrow.
