The top seed Elina Svitolina is through to the second round in Guangzhou, defeating a lucky loser Dalila Jakupovic 6-3, 6-3 in 69 minutes. The Ukrainian served at only 54% but saved four out of six break chances, taking half of the return points to grab five breaks and advance into the last 16.
Jakupovic kicked off the encounter with a break before Elina took charge, taking eight of the next nine games to forge the lead, breaking in games four and six of the opener to take it 6-34 after a hold at 15 in game nine.
Svitolina raced into a 5-1 lead in set number two with breaks in games one and five, wasting a match point on the return in game eight before sealing the deal on own serve a few minutes later. Anna Blinkova toppled Sara Sorribes Tormo 2-6, 6-1, 4-1, overcoming a slow start to dominate in sets two and three before the Spaniard had to retire after an hour and 40 minutes.
The 3rd seed Sofia Kenin took down Laura Siegemund 6-4, 6-2 in an hour and 27 minutes, suffering only one break from three chances offered to the German and stealing almost half of the return points to deliver four breaks from eight opportunities, enough to go through in straight sets.
The American raced into a 4-0 lead in the opener, losing serve once after that but closing the set in game ten on own serve. The youngster sailed through the last four service games in set number two, breaking Siegemund in games one and three to move over the top and make the best possible start.
After three hours and 27 minutes of an exhausting battle, Katarina Zavatska toppled Fiona Ferro 5-7, 7-6, 6-4 winning just two points more than her opponent. Both players scored six breaks (Zavatska had more chances) and pushed each other to the limits, with the opening two sets lasting for more than two and a half hours alone.
Ferro won the opening set 7-5 with a late break and was 4-2 up in the second, losing the advantage and missing the opportunity to seal the deal in the tie break despite being two points away from the finish line. In the decider, Zavatska opened a 4-2 lead and converted the fifth match point at 5-4 to prevail and move into the second round.
The 6th seed Saisai Zheng took down Yingying Duan 6-7, 7-6, 6-1 in two hours and 40 minutes, saving a match point in the 12th game of the second set and dominating in the tie break and set number three to avoid an early exit and advance into the last 16.
After playing in the final in Nanching on Sunday, Elena Rybakina had nothing more left in the tank for Seoul, retiring against the 5th seed Katerina Siniakova after 64 minutes and only two games won. The 4th seed Shuai Zhang ousted Kateryna Kozlova 6-2, 6-4 in an hour and 32 minutes, losing serve twice and earning five breaks that propelled her through.
Shuai Peng defeated the 2nd seed Qiang Wang 7-5, 6-2 after scoring seven breaks, not playing on a high level but doing enough to leave the pale rival behind.
