Bianca Andreescu vs Polona Hercog

This Cundinamarca Open semifinal pits two in-form players against each other — both had to win through the draw to get here. Andreescu's run is the one making headlines, with her semifinal arrival confirmed after a strong week, and she carries the bigger résumé into big moments. Hercog, the veteran, has done the same work without the spotlight. There is no documented head-to-head history or injury news to tip the scales. On momentum and big-match pedigree, the analytical edge tilts to Andreescu, though Hercog's experience keeps this genuinely competitive.
