Mirra Andreeva walks into this opener with a matchup she already solved a couple weeks ago, and nothing about Janice Tjen’s recent form suggests the rematch will look any different. Andreeva handled her 6-1, 7-6 in Cincinnati — one set completely one‑way, the other competitive but still controlled — and when two players meet again this quickly, the gap usually stays the same. Tjen has dropped 23 of her 39 matches this season, carries an 8-13 hard‑court record, and is winless in five tries against top‑20 opponents. She competes, but she doesn’t have the pace or the weapons to keep Andreeva from dictating. With Andreeva’s baseline patterns clicking and Tjen struggling to hold serve against elite hitters, this sets up as another short, straightforward win for the Roland Garros champion.

Sabalenka hasn’t been in top gear lately, but this matchup gives her a perfect runway to settle in. Even when her form dips, her opening‑round Slam record stays elite — 15 straight R1 wins, all in straight sets, and she’s covered this kind of spread in almost all of them. Osorio fights hard, but she doesn’t have the pace or the weapons to keep Sabalenka from dictating. Add in Osorio’s rough summer, her 2‑13 record vs top‑10 players, and a lopsided loss to Ann Li last week, and you get a matchup where Sabalenka’s power should take over quickly. If she keeps the double faults under control, this has all the signs of a short, one‑way opener.
