WASHINGTON (AP) Top-seeded Sam Stosur lost to 173rd-ranked wild-card entry Jessica Pegula in the Citi Open quarterfinals 7-6 (4), 6-3 on Friday.

Stosur, the U.S. Open champion in 2011, led 4-1 in the opening tiebreaker before losing six consecutive points to drop that set. The only break of the match came in the next-to-last-game, when Pegula went up 5-3, then served out the biggest victory of her career.

The 22-year-old Pegula moved into her first WTA semifinal. Her parents own the NFL's Buffalo Bills and NHL's Buffalo Sabres.

On Saturday, Pegula will face either Lauren Davis or Camila Giorgi for a berth in the final.

The other semifinal at the hard-court tournament will be No. 6-seeded Yulia Putintseva against No. 7 Yanina Wickmayer.

Wickmayer beat No. 4 Kristina Mladenovic 4-6, 6-3, 6-4, while Putintseva defeated Risa Ozaki 6-4, 6-2.
