Reasons:
1) Unlike Swiatek today (3 hrs.+), she's not needlessly tiring herself out playing doubles..playing every other day which
mitigates her fitness issues.
2) Ons has a much easier path to the SFs (Coco, who she beat in April on clay, & the winner of Stephens/Krejci. while Iga has Kostyuk & the winner of Kenin/Sakkari)
3) -140 horrible value on Iga away considering Rafa is -145.
4) Since the WTA is all about random fukkery, just like with Ostapenko who was +8000 at the time this would also be Jabeur's 1st WTA Title.
