(Reuters) -World number one Iga Swiatek's bid to win a third successive Stuttgart Open title came to an end in an enthralling 6-3 4-6 6-3 semi-final loss to Elena Rybakina on Saturday.

Rybakina ended Swiatek's perfect record in Stuttgart by handing the Pole her first defeat in 11 matches at the tournament and the Kazakhstani fourth seed will meet Marta Kostyuk in the final.
