Emma Raducanu and Katie Boulter will finish their Nottingham Open semi-final on Sunday after play was suspended shortly before 20:00 BST.

British number one Boulter, 27, will have it all to do if she is to defend her title against her Billy Jean King Cup team-mate after losing an epic first set 15-13 on a tie-break.

Neither player dropped serve in a high-quality encounter and both players had chances to win the tie break, with Boulter wasting three set points.

But it was 21-year-old Raducanu who carried the greater threat and she finally converted her sixth set point with a smash at the net.

The former US Open champion, who has fallen to 209 in the world after spending months out of the game recovering from injury, slipped awkwardly on the baseline early in the tie-break and was quick to ask for play to be suspended following the end of the first set after complaining the surface had become too slippery.

Boulter agreed and play will now resume on Sunday morning, with the final to be played later in the day.
