Britain’s Katie Boulter missed out on the biggest win of her career, losing in three sets to world number six Karolina Pliskova in the Tianjin Open quarter-finals.

Boulter, who has never beaten a player ranked in the world’s top 10, led 2-0 in the third set but lost 5-7 6-0 6-3.

Boulter, currently ranked 101 in the world, is still likely to break into the world’s top 100 for the first time.

She was appearing in only her second quarter-final at WTA level.
