Top seed Agnieszka Radwanska of Poland had to endure an hour and a half for a rain delay before reaching the semi-finals of the ASB women's tennis Classic in Auckland.
Once the skies cleared the world number four finished off the Russian Elena Vesnina in straight sets, 6-3 6-3.
Radwanska now plays the winner of the evening quarter-final between American Jamie Hampton and Kiki Bertens of the Netherlands for a place in the final.
Three rain delays also held up play in the second quarter-final before Yanina Wickmayer eventually beat fellow Belgian Kirsten Flipkens 6-3 6-4.
But there was controversy over a line call on match point...
The umpire over-ruled a lineman's call in Wickmayer's favour, despite television replays showing the ball was out.
Wickmayer says she feels for her opponent.
She will play Mona Barthel in tomorrow's semi-finals, after the German eighth seed thrashed Sweden's Johanna Larsson 6-2 6-1.
Barthel needed only three quarters of an hour to beat Larsson in straight sets.
