14:13 CET - What an utterly remarkable way to begin the Billie Jean King Cup quarter finals! Somehow, someway, Elisabetta Cocciaretto has produced a stunning escape act, fighting from a break down in the second set, as well as a double break down in the third, to win a thrilling contest against Yue Yuan in just under three hours, 4-6, 7-5, 7-5.
Yuan will be devastated that she wasn't able to get over the line, and will be kicking herself that she hasn't given China a 1-0 lead. Instead, Italy go up, and Jasmine Paolini will be looking to finish the job next.
13:28 CET - The rain has just not relented in Seoul, and as a result, play has been called off for the day, with matches being moved to tomorrow.
11:12 CET - Two-time Grand Slam champion Barbora Krejcikova has flown into the Seoul second round, claiming a thrashing 6-1, 6-2 win over qualifier Tatiana Prozorova.
Meanwhile, the rain has returned, so play has been paused in the South Korean capital.
11:08 CET - Play is set to get started in the next few minutes at the Billie Jean King Cup Finals, with Elisabetta Cocciaretto taking on Yue Yuan in the opening rubber between defending champions Italy and hosts China, before Jasmine Paolini faces Xinyu Wang.
