Swiatek made to wait as Seoul quarter-finals washed out

Iga Swiatek's Korea Open quarter-final against Barbora Krejcikova was postponed Friday as rain washed out the day's play in Seoul.

All four singles quarter-finals were pushed back to Saturday as bad weather continued to affect the tournament, which has been hit with delays all week.

The semi-finals will take place on Saturday evening, with mostly warm and sunny weather forecast for much of the day.

Six-time Grand Slam champion Swiatek opened her campaign with a 6-3, 6-2 win over Romania's Sorana Cirstea on Thursday.

It was the world number two's first outing since she lost in straight sets to eventual finalist Amanda Anisimova at the US Open.

Two-time major champion Krejcikova advanced to the quarter-finals after beating Britain's Emma Raducanu in three battling sets.
