SEOUL, Aug 30 — China’s badminton world number one Shi Yuqi continued his indifferent run of form with a quarter-final loss to Hong Kong’s Lee Cheuk-yiu at the Korea Open today.

Shi ended double Olympic champion Viktor Axelsen’s 131-week reign at the top of the rankings in June but the Chinese player has struggled to consolidate his position in recent weeks.

He lost in the quarter-finals at the Paris Games before being ousted in the semi-finals of last week’s Japan Open by French teenager Alex Lanier.

Shi went down 21-13, 21-15 to world number 17 Lee in South Korea.

The 28-year-old Shi has won four tournaments on badminton’s world tour this year.
