EMMA RADUCANU believes trying to “let go” of frustration helped her seal a straight-sets victory over Yuan Yue at the Korea Open today.

The 21-year-old needed seven match points to clinch a hard-fought 6-4 6-3 victory over the eighth seed to progress to the quarter-finals of the competition.

Raducanu edged in front following a close first set and powered ahead at the start of the second before holding off a comeback from Yuan.
