Italy-Ukraine: without Kostyuk, the number 2s decide
Italy comes into Saturday's semifinal in Shenzhen with an edge the singles rankings don't show: doubles. Sara Errani (world number 13 in the discipline) and Jasmine Paolini are the third point almost guaranteed in every tie, and in a format of two singles plus doubles, that point counts as much as the other two. Without Marta Kostyuk, sidelined by the wrist injury confirmed by an MRI after the US Open, Ukraine has to take both singles matches. The tie comes down to the clash between the number 2s.
The doubles point is already spoken for, and Ukraine knows it
In the quarterfinals, Ukraine closed out the tie with doubles, 6-3, 6-3 for Anhelina Kalinina and Lyudmyla Kichenok over Kempen and Salden, against a mismatched pairing, with Salden (108) on court alongside the higher ranked Kempen (34). Kichenok is a genuine specialist, world number 52 in doubles. Kalinina sits at 140 and comes off a season built entirely around singles.
Against Errani and Paolini, the jump is of a different order. Guo Hanyu and Jiang Xinyu, a settled pairing on tour, took a set off the Italians and nothing more (6-3, 5-7, 6-3), just hours after Paolini had already closed out her singles match against Zheng Qinwen. Olympic gold and a Roland Garros title over the last three seasons translate into net instincts that a pair thrown together for the occasion can't make up in one evening.
Ukraine lost the 2025 semifinal to Italy. To turn it around, they need a 2-0 lead before doubles.
The likely number 2 matchup: Kalinina against Italy's weak spot
This is where the semifinal will be won or lost. Elisabetta Cocciaretto took the court against China and lost 0-6, 2-6 to Zhang Shuai, Italy's worst performance of the tournament. This is the same player who won Hobart in January and beat Coco Gauff in Doha in February, climbing back into the top 40. Today she's number 67, and in the quarterfinals she was the only Italian who didn't win her match.
Tathiana Garbin's alternatives are Lucia Bronzetti (130) and Tyra Caterina Grant (150). Neither is an upgrade on paper.
Marchenko hasn't announced the lineup yet, but Kalinina is the expected pick, and she's Ukraine's in-form player. Back after six months out, she climbed into the top 50 with three straight 125 finals in Antalya and a WTA final in Rabat. Against Otzipka she dropped the first-set tie-break and then won 6-1, 6-1. It's how she's always won: by accumulation, few winners, long rallies, the opponent cracking as the match stretches out.
Her career record shows 57% wins on clay against 44% on hard courts. Shenzhen's medium-paced indoor hard court isn't her natural habitat, but her two 125 titles in Limoges (the most recent in December 2025) both came indoors. The surface split promises Italy less than it seems to.
Svitolina, the number 7 ranking, and last year's precedent
Elina Svitolina is putting together her best season in years: a semifinal in Melbourne, quarterfinals in Paris, the Rome title after beating Swiatek and Gauff both in three sets. On paper, her singles match against Paolini is Ukraine's safest point.
The quarterfinals say something else. Svitolina walked on court with a chance to close out the tie against Greet Minnen, ranked 217, and won the first set 7-6(5) before losing 4-6, 4-6. Asked afterward about how much rankings matter in this format, she said it counts for less than the bench and a different kind of pressure than the one on tour.
Paolini, in Billie Jean King Cup, delivers. In the quarterfinals she extended a winning streak in the competition across singles and doubles combined. And twelve months ago, in this same semifinal, she was down 6-3, 4-2 to Svitolina and won 3-6, 6-4, 6-4. The head-to-head still reads 2-1 for Svitolina, but the one time the two found themselves in this exact spot, Paolini won.
The forecast, and what could upend it
Italy starts as the favorite, and the margin is wider than a number 7 versus a number 20 comparison suggests. With doubles almost banked, Ukraine needs a 2-0 in singles, and to get there it has to win a match (Kalinina against Italy's number 2) that has become the tie's most uncertain outcome since the quarterfinals, then repeat against Paolini an attempt that already failed a year ago.
The forecast breaks if Kalinina beats Italy's number 2. From there the semifinal narrows to Svitolina against Paolini, and the Svitolina who won Rome takes that match. The second signal concerns Paolini's workload, since she plays both singles and doubles in every tie. If Italy loses the number 2 singles, Paolini has to win both her matches on Saturday, with Svitolina sandwiched in between.
