Tjen, the No. 7 seed and world No. 37, holds the ranking and seeding edge over wild-card entrant Yastremska (No. 107) in this Monterrey Open first-round hard-court matchup. Their only prior meeting ended in a straight-sets win for Tjen on hard courts in Dubai earlier this year. Both players enter with recent struggles—Tjen at 3-7 in her last 10 matches and Yastremska coming off consecutive losses—yet Tjen’s stronger overall hard-court results and consistent top-50 presence shape the consensus view of her as the more reliable option. Surface conditions, draw position, and any late fitness updates remain key variables heading into Monday’s encounter.
