Iga Swiatek will face Ekaterina Alexandrova in the Korea Open final after both top seeds ground through a two-match marathon and still found the tennis to finish strong at night. Super Saturday asked for resilience and clean patterns; the No.1-seeded’s return pressure and the No.2-seeded’s first-strike serving answered in full.
Quarterfinals — the day breaks open
Swiatek d. Krejcikova 6–0, 6–3
Swiatek set the tone early and never allowed Krejcikova to organize behind her delivery. She won 67% of first-serve return points and posted a Return Rating of 286, a suffocating combination that produced six breaks from seven return games. Even on her own second serve she held firm (63% won), turning neutral starts into plus-one forehands and sprinting to 61% of total points and a Dominance Ratio of 1.56. The bagel wasn’t a flourish; it was the game plan executing on every ball.
Joint d. Tauson 6–0, 6–3
Maya Joint matched the vibe with a blistering opener of her own. She ripped through second-serve looks—83% return points won on Tauson’s second ball—and converted five of seven break chances. The serve held up under pace (67% first-serve points, 61% second-serve points), yielding 12 of 15 games and a commanding DR 1.64. It was the most balanced, front-foot tennis of her week.
Siniakova d. Lamens 6–1, 7–5
Siniakova’s match pivoted on stretches of sustained momentum. A sparkling 13-point run across the first set and change framed a performance built on 73% first-serve points won and 47% first-serve return points won. Lamens surged late, but Siniakova’s weight of return—six breaks across ten return games—kept the Czech in control (DR 1.36).
Alexandrova d. Seidel 6–2, 6–3
Alexandrova brought the thunder. Seven aces, 79% behind first serve, and 54% first-serve return points won crushed time and space. She balanced aggression with just enough margin—Return Rating 260, 60% of total points, 6/10 on break points—to move through with minimal fuss.
Semifinals — separation on the second shift
Swiatek d. Joint 6–0, 6–2
The evening session accentuated Swiatek’s biggest edge: repeatable return depth. She took 71% of Joint’s first-serve points and a staggering 86% on second-serve returns, turning service games into defensive scrambles. Add 79% won behind her own first serve and the scoreboard raced: 6/10 breaks, Dominance Ratio 1.78, done in 1h07m. On a double-day, economy matters; Swiatek banked it.
Alexandrova d. Siniakova 6–4, 6–2
This was about adjustments. After a tight first set, Alexandrova flipped the match by owning the second-serve exchanges—66% won on her second to Siniakova’s 46%—and by passing pressure tests (71% break points saved). With a Return Rating of 208 and 57% of total points, she found the cleaner end of the rallies and pulled away.
The final — return fire vs first strike
Swiatek’s path has been defined by return superiority and scoreboard compression: across the two Saturday wins she consistently lived above 70% on first-serve return points and converted chances at a ruthless clip. Alexandrova arrives with the week’s most disruptive first ball (aces, pace, early contact) and newly reliable second-serve production under stress.
Three swing factors to watch:
- First-serve speed vs depth of return: Alexandrova must keep her first-serve hit spot high; Swiatek’s depth neutralizes pace better than most.
- Second-serve outcomes: The night semi showed Alexandrova winning two-thirds of those points; maintaining that against Swiatek’s red-line return would be a match changer.
- Conversion on pressure points: Swiatek led that metric 67% in the semi; if she sustains that, Alexandrova’s margin for error narrows fast.
The headline holds: the top two seeds survived Super Saturday—and did it with their identities intact. Now they meet with clear terms: Swiatek’s relentless return patterns versus Alexandrova’s first-strike ferocity. The player who dictates more starts on serve will likely dictate the finish.
