Coco Gauff Narrowly Avoids Second-Round Wimbledon Upset

Coco Gauff is through to the third round of Wimbledon 2026. The No. 7 seed opened her campaign with a dominant 6-2, 6-1 win over Germany’s Tamara Korpatsch in just 54 minutes on June 29 — her most lopsided Wimbledon opening-day score, and a result that ended a grass-court winless streak dating back to 2024 .

The second round was far tougher. Facing Argentina’s Solana Sierra on July 1, Gauff came within two points of a first-round-style upset loss, needing a third-set tiebreak to escape  . She took the opener 6-3, dropped the second 3-6, then survived a tense decider, closing it out 7-6(10-7)  after trailing in the breaker before reeling off the final points to seal the win .

That victory books her a third-round meeting against the winner of Ann Li–Zeynep Sonmez, a match Gauff enters as a heavy favorite — she’s 3-0 all-time against Li and has never faced Sonmez . It’s a meaningful milestone for the two-time major champion: Gauff has never made it past the fourth round at Wimbledon , and last year ended in a first-round exit, so reaching round three continues the deeper run she’s chasing on grass this time around.
