World No. 1 Simona Halep was swept aside 6-2, 6-4 by 44th-ranked Kaia Kanepi yesterday, the first top-seeded woman ever to lose in the US Open first round. It was a second straight first-round exit at Flushing Meadows for Romania's Halep, who dropped her opening match to Maria Sharapova last year.

The French Open champion had no answer for Kanepi's powerful groundstrokes. The Estonian fired 26 winners to Halep's nine, and even her 28 unforced errors weren't enough to derail her challenge as she brought the rallies to quick ends and remorselessly punished Halep's second serve.
