Andy Murray maintained his record of never losing in the Wimbledon first round with an encouraging victory over fellow Briton Ryan Peniston.
Two-time champion Murray, ranked 40th in the world, started slowly against wildcard Peniston on Centre Court.
But the Scot showed his greater class to fight off early break points, before going up a gear to win 6-3 6-0 6-1.
British number one Cameron Norrie, a semi-finalist last year, won 6-3 4-6 6-1 6-4 against Czech Tomas Machac.
But Dan Evans, seeded 27th, lost 6-2 6-3 6-7 (5-7) 6-4 to France’s Quentin Halys.
Murray and Peniston, who is ranked 268th, were among the few players who could complete their first-round matches on Tuesday, with the all-British affair taking place under the Centre Court roof.
Later on, as the rain that decimated day two beat down on the Court One roof, 12th seed Norrie came through a tricky test against qualifier Machac.
On a court where he won in the last 16 and quarter-finals last year, Norrie produced a largely composed display as he started his bid to replicate the best Grand Slam run of his career.
“It was a lot of fun coming out to that court, so special, a lot of good memories there,” he said.
“I reckon I played a really good match with some normal drops in there but there was a lot to learn from and take from that match. It was a good day and nice to get the win.”
Both Norrie and Murray, who could face each other in the fourth round, are still waiting to find out their next opponents.
Norrie, 27, will play American Christopher Eubanks or Brazil’s Thiago Monteiro, while Murray, 36, faces Greek fifth seed Stefanos Tsitsipas or 2020 US Open champion Dominic Thiem.
Those contests were among many matches scheduled to take place on Tuesday but cancelled by heavy and prolonged downpours in south-west London.
Fellow Britons Katie Boulter and George Loffhagen started their matches in the morning before being forced off the outside courts shortly after 12:00 BST.
Play was suspended for several hours and, with the weather not forecast to improve much over the rest of evening, almost all of the day’s other matches were called off.
