Swiatek to miss Korea Open due to fatigue, Pegula out with injury

World number one Iga Swiatek has pulled out of the Korea Open due to fatigue, tournament organisers told reporters on Friday.

Defending champion and U.S. Open finalist Jessica Pegula has also pulled out from the WTA 500 event in Seoul with a rib injury.

Poland's Swiatek, who won the French Open in June and took bronze in the Paris Olympics before losing to Pegula in the U.S. Open's quarter-finals, had also withdrawn from last month's Canadian Open citing fatigue.

Former Wimbledon champion and world number four Elena Rybakina will also miss the Korea Open with a back injury, while U.S. Open semi-finalist Emma Navarro has pulled out due to a change of schedule.

Korea Open will take place between Sept. 16-22.
