Emma Raducanu’s first match since the US Open, against Jaqueline Cristian at the Korea Open, has been postponed because of rain.

Raducanu pulled out of the Billie Jean King Cup to prioritise the WTA tour and continue her work with new coach Francisco Roig, taking up the opportunity of a wildcard in Seoul.

But heavy rain fell on the Korean capital, causing her opening match against Cristian to be postponed until Wednesday, with an approximate start time of 6am in the UK.

Raducanu is on the hard side of the draw, with US Open quarter-finalist Barbora Krejcikova waiting in the second round and Iga Swiatek in the same quarter.

The rain has not relented, and tournament organisers have decided to pack up for the day.
