June 20 (Reuters) – World ⁠number one Aryna Sabalenka of Belarus ⁠suffered a shock defeat in her ‌grass-court build-up to Wimbledon on Saturday, losing to American Jessica Pegula 6-4 6-7(4) 6-0 in the Berlin ​Open semi-finals.

The 28-year-old, who exited ⁠the French Open ⁠in the quarter-finals to Russian Diana Shnaider, ⁠struggled to ‌find her rhythm after a slow start, and Pegula took ⁠the opening set following an early break.

After ​a ‌rain delay, Sabalenka took the second-set tiebreak ⁠before Pegula ​reasserted control to race through the decider.

All four of the Belarusian’s Grand Slam titles — ⁠her most recent at the ​2025 U.S. Open — have come on hard courts, and she is still chasing a first ⁠Wimbledon crown after three semi-final runs. She lost this year’s Australian Open final to Elena Rybakina in three sets, a ​year after finishing runner-up ⁠to American Madison Keys.

Pegula, the 2024 Berlin ​champion, will face either Czech ‌Linda Noskova or the ​Philippines’ Alexandra Eala in Sunday’s final.
