Wimbledon star Cori Gauff, top seed Sloane Stephens exit Washington Open after opening round losses

Washington: Coco Gauff, the American teen who electrified Wimbledon with a last-16 run, and US top seed Sloane Stephens crashed out Tuesday in round one of the WTA Washington Open.

Eighth-ranked Stephens, the 2017 US Open champion, lost to Sweden's Rebecca Peterson 6-2, 7-5 while 15-year-old qualifier Gauff fell to Kazakhstan's 84th-ranked Zarina Diyas 6-4, 6-2.

"Every loss is something I learn from," Gauff said. "Overall it was a good experience."

The US Open women's hardcourt tuneup event lost its only top-10 entrant in Stephens and its star attraction in 146th-ranked Gauff, whose loss came in her first main-draw match since she fell to eventual champion Simona Halep at Wimbledon.
