Alina Korneeva vs Mananchaya Sawangkaew — R32 — Korea Open

Alina Korneeva opened the Korea Open with a 6-4, 6-2 win over Mananchaya Sawangkaew, her first win since the Canadian Open in early August. The 19-year-old, ranked WTA No. 81, needed 1 hour 22 minutes in the first round of the Seoul WTA 250, where the betting market had favored her at 67%. Korneeva broke in the second game of each set, and each time Sawangkaew got the break back — in game 7 of the opener for 3-4, then in game 3 of the second set for 1-2. Neither reprieve held. Korneeva broke again in game 10 to take the first set and in game 4 of the second for 3-1, finishing with five of eight break points converted to Sawangkaew's two of seven. Sawangkaew, 24, held four of her nine service games and hit nine double faults, six of them in the first set. She arrived at WTA No. 88, her season peak, after starting the year at No. 247. The two had no prior meetings on record.
