World No.1 Aryna Sabalenka's Wimbledon preparations have suffered a setback as she was beaten by American Jessica Pegula 6-4 6-7(7-4) 6-0 in the Berlin Open semi-finals.
Pegula will face Linda Noskova in the final after the Czech eighth seed ended the run of Filipino Alexandra Eala with a 6-2 6-4 victory.
Sabalenka, who exited the French Open in the quarter-finals, struggled to find her rhythm after a slow start, and Pegula took the opening set following an early break.
