In the first tour-level clay-court match of her career, Ukraine's Daria Snigur came away with a thrilling 6-3, 3-6, 7-6 (13) victory over Australia's Daria Kasatkina in first-round action of the Mutua Madrid Open on Thursday.

Snigur, ranked 98th in the world, saved four match points before winning the marathon finish, which goes down as the longest first-to-seven, tour-level third-set tiebreaker in eight years and the sixth-longest in a WTA match this century.

Kasatkina, a 2022 French Open semifinalist, saved 17 of 24 break-point chances. Each competitor won 50% of both their service and return points. Snigur will next face No. 4 seed Iga Swiatek of Poland.

Seven Americans were in action during an extensive 22-match day of action in the Spanish capital. All 32 seeded competitors earned first-round byes in the 96-person event.

Alycia Parks won her opening-round match over Italy's Elisabetta Coccioretto 6-3, 6-2, setting up a second-round clash with fellow American and No. 31 seed Ann Li.

Parks finished off her opening match in just 74 minutes. She hit just 52% of her first serves but won 71.4% of her service points, saving all three break points she faced while converting 3 of 7 on Coccioretto's serve.

Two other Americans fell, with Taylor Townsend losing 6-4, 6-2 to Great Britain's Katie Boulter while Elvina Kalieva took a 6-3, 6-4 defeat against Katerina Siniakova of the Czech Republic.

Boulter will next face fifth-seeded American Jessica Pegula. No. 3 seed Coco Gauff will open against France's Leolia Jeanjean, who blew past Russia's Oksana Selekhmeteva for a 6-4, 6-1 victory.

There were also two battles between U.S. players on Thursday. Caty McNally bested Katie Volynets 6-1, 6-2 in 94 minutes and will face No. 10 Victoria Mboko of Canada in the second round. Sofia Kenin, who won the 2020 Australian Open, defeated Ashlyn Krueger 7-6 (2), 6-4 to book a matchup against No. 32 Qinwen Zheng of China.

Elena-Gabriela Ruse of Romania beat Croatia's Antonia Ruzic 6-3, 4-6, 6-0 and will face No. 2 seed Elena Rybakina of Kazakhstan in the Round of 64.

That was one of seven matches contested on the day which went to a third set. However, one of the more thrilling matches was Argentina's Solana Sierra holding off Ukraine's Dayana Yastremska 7-6 (10), 7-6 (8) in a match which lasted nearly 2 1/2 hours despite only going two sets.

In other two-set matches, Italy's Tyra Caterina Grant defeated France's Elsa Jacquemot 6-1, 6-2, Switzerland's Simona Waltert beat Oleksandra Oliynikova of Ukraine 7-5, 6-0, Indonesia's Janice Tjen swept Russia's Alina Charaeva 6-4, 6-2, Colombia's Emiliana Arango beat Australia's Talia Gibson 6-3, 6-2, Alexandra Eala of the Philippines defeated Russian Anastasia Pavlyuchenkova 6-3, 6-3, Hungary's Dalma Galfi bested Australia's Ajla Tomljanovic 7-6 (7), 6-4, Turkey's Zeynep Sonmez beat Spaniard Carlota Martinez Cirez 7-5, 6-2 and China's Shuia Zhang overcame Germany's Eva Lys for a 6-4, 6-3 victory.
