Janice Tjen enters the Monterrey Open first-round matchup against Dayana Yastremska as the clear favorite on hard courts, bolstered by a straight-sets victory over the same opponent in Dubai earlier this year. Ranked No. 37 and seeded seventh in the WTA 500 event, Tjen holds a stronger 2026 hard-court record and has shown greater consistency against mid-tier opposition despite recent losses to top players like Mirra Andreeva. Yastremska, now outside the top 100 at No. 107, enters with a sub-.500 seasonal record and limited recent success on the surface. The hard-court setting favors Tjen’s baseline game and return effectiveness, though Yastremska’s power could create opportunities if she finds early rhythm.
