Dayana Yastremska vs Maja Chwalinska Prediction — Beijing, Friday, October 2, 2026

Dayana Yastremska and Maja Chwalinska meet in Beijing on Friday, October 2, 2026, with first serve at 12:30 AM ET. Chwalinska is priced at -244, and the Dayana Yastremska vs Maja Chwalinska prediction most bettors will land on is the same number the market already shows: Chwalinska in straights. The question worth asking is whether that price is actually backed by anything beyond seeding.

It is. The model's own read lines up with the market here, but the card marks this one PASS. That means no official action is going out on this match, whatever the reasoning underneath says about who is better.

Why the model leans Chwalinska

Strip away the single headline result and look at twelve months on hard courts. Chwalinska holds serve 65% of the time and breaks 41%, good for an 11-8 record against opponents rated around p49. Yastremska holds 59% and breaks 30%, going 8-15 against a similar-strength p60 field. Both numbers point the same direction, and a gap that size tends to show up on the scoreboard, not just the spreadsheet.

Chwalinska's recent form backs that baseline instead of contradicting it. She rolled an ankle on match point at Wimbledon in late June and withdrew from Hamburg, then went 1-4 on hard in August against Gibson, Bucsa, Shnaider, Parks and Townsend. In September she turned it around in Singapore, going 3-1 with a 6-2 6-2 win over No. 19 Mertens in which she won 70% of first-serve points and 60% of second-serve points, with 10 winners against 7 unforced errors. That is a player back to her twelve-month level, not above it, which is exactly what the model needs to see before it trusts the larger sample over the smaller one.

The case for Yastremska

Yastremska's lone data point since the horizon opened is a genuinely good one. She beat Caty McNally 6-3 6-4 in Beijing's first round, holding all ten of her service games and facing zero break points while winning roughly 83-85% of first-serve points. She did that as a late alternate standing in for Cocciaretto, with no qualifying matches behind her and only one rest day before this one.

That is also the entire case. Before Beijing she had not played since August 31, and the 1-4 run she took into that layoff included hard-court losses to Tatjana Maria and to Tjen, both slice-and-variety players in the mold Chwalinska plays. If Yastremska's first-round serve level carries over, the plan is straightforward: get into rallies behind flat power and go after a soft second serve early, the way Fernandez won 12 of 18 of those points off Chwalinska in the Singapore semifinal, and the way Gibson and Parks both beat Chwalinska on hard in August. It is a real path. It is also one 50-point sample against a mid-level opponent coming off a four-week layoff, not a reversal of eight months of hard-court results.

The number that matters

On serve versus return, Chwalinska wins 48% of her return points and lands 73% of first serves. Yastremska double-faults on 7.1% of her service points and wins only 45% of second-serve points. Put those together and the return side of the court favors Chwalinska before either player's recent form even enters the conversation.

None of that changes where the card lands. This is a PASS. No units are going on Dayana Yastremska vs Maja Chwalinska, and everything above explains why the numbers lean Chwalinska, not why the bet isn't being made.

The verdict

Chwalinska is priced at -244 for Friday's 12:30 AM ET first serve, and both the twelve-month hard-court numbers and her recent Singapore form back that price. The card still reads PASS, so this one is a pass: no official action, win or lose.
