World No.3 shuttler Saina Nehwal faltered once again in the women's singles quarter-final of the $1 million Korea Open Super Series Premier against Li Han of China here Friday.

The unseeded Li won her first match against Saina in three meetings here at the S.K. Handball Stadium. Li won 21-14, 15-21, 21-12 in 59 minutes, preventing Saina from bettering her record in the tournament where she also lost in the quarter-final in 2012.
