Back Peyton Stearns at -275. The model rates her 71% likely to advance in this Grand Slam encounter, matching the top rating on the slate. The price implies roughly 73% probability, yet the data still shows a narrow positive expected value. Four-star designation reinforces the lean.

Cristina Bucsa vs Bianca Andreescu — Bianca Andreescu ML
