Top seed Carlos Alcaraz overcame the weather to advance into the third round at the Shanghai Masters.
The Spaniard’s match against Gregoire Barrere of France was played under the roof after rain caused play to be suspended in China.
But he cruised through 6-2 7-5 against the world number 73.
Britain’s Cameron Norrie was one of the players affected when play was called off for the day because of persistent heavy rain.
Norrie was 3-2 up in the deciding set against American JJ Wolf having lost the first set 6-3 before taking the second 7-5.
Fellow Briton Dan Evans was unable to get on to court for his scheduled match against Mikhail Kukushkin of Kazakhstan.
Elsewhere, second seed Daniil Medvedev and fourth seed Stefanos Tsitsipas also advanced to the last 32.
Russian Medvedev was a 6-3 6-3 winner over Chile’s Cristian Garin while Greece’s Tsitsipas defeated Australian qualifier Rinky Hijikata 6-4 6-2.
And Italian sixth seed Jannik Sinner joined them in the next round after a 7-6 (9-7) 6-2 victory over American Marcos Giron.
