Singapore WTA preview: Vekic–Wang rematch leads September 22 card

The Singapore first round begins on September 22 with an indoor-hard card built around uncertain confidence and immediate pressure. Donna Vekic meets a recent conqueror, while Barbora Krejcikova and Maria Sakkari try to turn superior class into orderly wins.
Alycia Parks brings the sharpest fitness concern, and Tatiana Prozorova faces Sofia Costoulas in a match with little margin between them. I have these five matches at the centre of the day:
- 04:30 — Alycia Parks — Mei Yamaguchi
- 05:30 — Tatiana Prozorova — Sofia Costoulas
- 06:00 — Donna Vekic — Xinyu Wang
- 10:35 — Barbora Krejcikova — Anna-Lena Friedsam
- 12:00 — Maria Sakkari — Linda Fruhvirtova
Times are UTC.
Alycia Parks — Mei Yamaguchi
Parks should own the first strike in these conditions, but her right shoulder changes the entire calculation. It was heavily taped in Guadalajara, where she reportedly looked uncomfortable and struggled to find her usual serve speed. No diagnosis has been confirmed.
Yamaguchi lost decisively to Kyoka Okamura in the final qualifying round, then entered as a lucky loser. That route leaves her with little recent momentum but useful knowledge of the court and none of the pressure attached to being the favourite.
Parks has won two of three indoor matches this season, and a normal service motion would put the contest on her racquet. Yamaguchi must block returns deep, keep Parks serving and make the shoulder answer the same question for more than one set.
I think Parks is still closer to the win, but the five-game handicap asks for more certainty than her shoulder currently provides. Yamaguchi at +5 looks competitive if Parks begins guiding the serve rather than releasing it.
Tatiana Prozorova — Sofia Costoulas
Prozorova arrives rested but short of match play, while Costoulas has already been competing in Asia. The reward is a second-round meeting with Alexandra Eala, which gives a low-profile first round a clear competitive edge.
Prozorova’s direct hard-court game is better suited to taking command early. Her 6-2 indoors record this season is relevant, although three straight recent defeats raise a fair question about how quickly she will settle.
Costoulas has repeatedly started well and then lost penetration once opponents changed the rally. She must protect her court position after the first two shots; otherwise Prozorova can step inside the baseline and dictate without taking unnecessary risk.
I give Prozorova a narrow edge because her first strike should carry more weight indoors, but this remains the murkiest match of the five. The under 22.5 games is plausible if one player controls court position early, yet a three-set swing would surprise nobody.
Donna Vekic — Xinyu Wang
This rematch turns on discipline after the first attack. Vekic wants serve, forehand and a clean finish; Wang wants to absorb that burst, restore depth and force one more difficult ball.
Vekic leads the head-to-head 2-1. She won 6-4, 6-4 indoors in Courmayeur in 2021 and 6-2, 6-4 in Dubai in 2024, but Wang reversed the pattern in Cincinnati last month, recovering from a set down to win 3-6, 6-1, 6-4.
That Cincinnati result fits Vekic’s recent problem. She also led Ann Li at the US Open before losing 7-5, 6-7, 4-6, and her level became less secure as the rallies and pressure games accumulated. The scoreboard is not employed to provide counselling.
Wang’s US Open loss to Anna Kalinskaya was steadier in shape: she controlled the middle set before falling 5-7, 6-2, 3-6. Her task here is to make Vekic hit through a balanced defender rather than allowing her to finish at net.
I think Wang is marginally closer because she has the more reliable rally tolerance and recently solved this matchup. Vekic’s serve keeps it tight, so over 22.5 games looks more natural than a quick finish.
Barbora Krejcikova — Anna-Lena Friedsam
Krejcikova has the higher ceiling by a wide margin, but Friedsam arrives with something the favourite lacks: two completed matches on these courts. The German came through qualifying in straight sets and recovered from an early deficit against Anastasia Kulikova.
Krejcikova’s North American hard-court stretch ended with poor timing and depleted energy. After the US Open she said, “I’m simply not in the best state—the battery is empty” (iDNES). She reported no major injury, making the break before Singapore potentially valuable.
Friedsam must attack before Krejcikova begins changing height, pace and direction. Krejcikova’s priority is a clean serve routine and patient construction; if she avoids donating early return games, her variety should steadily remove Friedsam’s balanced hitting positions.
I expect Krejcikova to win in straight sets, although the opening games may be competitive while she finds her timing. Her return quality and wider tactical range should eventually make the six-game handicap reachable.
Maria Sakkari — Linda Fruhvirtova
Sakkari’s physical advantages are clear, but this is another examination of how she handles the finish line. She escaped Robin Montgomery from a losing position at the US Open, then reversed the story by surrendering a strong lead against Yuliia Starodubtseva.
Sakkari has identified the issue herself: “We’re not machines; we’re not robots where you just press the button and you play with confidence” (US Open). She added that confidence comes through match wins, which makes the pressure games here more important than the ranking gap.
Fruhvirtova has won three of her last five hard-court matches, but those victories came against much lower-ranked opposition. She lost her next two and struggled to protect serve in Monday’s doubles, although the match gave her a useful feel for the court.
This is the sort of contest coaches recreate with a basket of second serves: Sakkari must attack without rushing, while Fruhvirtova must redirect pace without changing direction too early. Sakkari won their only previous meeting 6-4, 6-2 in Beijing in 2023.
I expect Sakkari’s forehand weight and return pressure to produce a straight-sets win. Fruhvirtova can keep individual games close, but Sakkari should create enough second-serve pressure for the five-game handicap to hold.
Five tests of control before Singapore settles
Vekic–Wang is the most complete contest because both women can seize the baseline and neither has made closing matches look routine. Parks’ shoulder is the main physical question, while Krejcikova’s energy and Sakkari’s confidence carry the largest reputational stakes.
I expect the day to reward disciplined serving more than raw pace, particularly when second serves come under pressure. The AI cappers handle the concrete picks on the individual match pages, where the positions become more specific.
