Katie Boulter lost 6-1 6-4 to Katerina Siniakova in the semi-finals of the Japan Open.

Boulter had reached her third WTA semi-final of the 2026 season and has reclaimed her place as British No 1 from Sonay Kartal.

But her run came to an end in Osaka with Siniakova starting their semi-final match up strongly.

The Czech won the first five games of the match and Boulter had to save a set point to win her first game.

Boulter stirred hopes of a fightback when she broke Siniakova but her opponent soon seized back control.

The Briton showed greater resistance in the second set but Siniakova served out for a straightforward victory.

Elena Rybakina is looking to defend her Ningbo Open title after beating Diana Shnaider in their semi-final on Saturday.

"It was an important game and a very long one," Rybakina said about closing out the first set. "It was a struggle on my serve. There were so many opportunities. But I'm glad that in the end it went my way."

Taylor Fritz reached his fifth ATP Tour final of the year after picking up a straight-sets win over fellow American Tommy Paul in the Grand Prix Auvergne-Rhone-Alpes semis in Lyon.
