Switzerland's Jil Teichmann meets Turkey's Zeynep Sonmez in the Second Round on Thursday, 29 October at 1:00 pm AEDT, and the odds tell a clear story — the Turkish world No. 64 opens a commanding 1.40 favourite while the left-handed Swiss sits out at 2.80. Both players arrive on the back of victories, but the form lines and career trajectories paint contrasting pictures.
Teichmann, ranked 168th and playing with her back against the wall this season, has managed a 7–2 record in 2026 but carries a career ledger of 100–106. Sonmez, meanwhile, has pieced together a 21–23 year and owns a near-identical 47–49 career mark. The head-to-head is blank — these two have never crossed paths — so we're reading the recent form tea leaves and weighing the market's confidence in the higher-ranked Turk.
Who will win?
Sonmez owns the higher ranking and the market backing, but her recent stretch has been anything but smooth. She's 3–2 across her last five outings, bookended by wins over Sara Sorribes Tormo and Rebecca Marino but punctured by straight-sets losses to Yulia Putintseva and Maddison Inglis. Coming off that three-set grind against Sorribes Tormo last Tuesday, she'll bring momentum but also tired legs — three-setters have a way of lingering.
Teichmann's sample is smaller — just three recent matches on the ledger — but the Swiss left-hander is coming off a tidy win over Simona Waltert in straight sets on Tuesday, 27 October. Before that she dropped a match to TBD and notched another straight-sets win earlier in the month. The southpaw game can be a puzzle for opponents who haven't seen it lately, and with no head-to-head history Sonmez will be working out the angles on the fly.
The market has spoken emphatically in favour of Sonmez, and the ranking gap — 104 places — is not nothing. But Teichmann's left-handed angles and her 78 per cent win rate this season suggest she's dangerous when dialled in. For punters hunting value in our tennis betting tips, the Swiss at 2.80 offers a genuine upset case if she can extend the rallies and lean on that lefty serve early.

Jil Teichmann vs Zeynep Sonmez
Final call
Sonmez is the rightful favourite on paper — higher rank, deeper recent form sample, and the market's clear lean. But Teichmann's season win percentage and the southpaw wrinkle make her more than a live underdog. Both players won their last starts, both have question marks around consistency, and neither has a clear psychological edge from past meetings. This shapes as a coin-flip dressed up as a mismatch, and the 2.80 on the Swiss lefty looks generous if she brings her best stuff to the court on Thursday arvo.
