Qualifier Emma Navarro of the US upset third-seeded Maria Sakkari of Greece 6-4, 0-6, 7-6 (4) on Thursday to advance to the semi-finals of the San Diego Open.
Navarro scored her first win over a top-10 opponent, as both players were making their San Diego Open debut. Sakkari’s loss meant all the top three seeds made early exits.
Barbora Krejcikova of the Czech Republic, seeded fourth and a wild-card entrant, beat seventh-seeded Beatriz Haddad Maia of Brazil 6-5, 6-3.
“It’s very difficult to play her and it’s more difficult because we play doubles together and I really like her,” said Krejcikova. “I knew she was going to fight to the very end, and I was ready for that.”
Krejcikova advanced to the semi-finals where she will face unseeded Danielle Collins who upset second-seeded Caroline Garcia of France 6-2, 6-3.
American Sofia Kenin scored a 6-2, 6-2 win over unseeded Anastasia Potapova of Russia. On Wednesday Potapova had defeated Ons Jabeur, the top seed.
