I think Miomir Kecmanovic will defeat Francis Tiafoe with a score of 2:1. Kecmanovic has the advantage on clay court, and in their previous meetings he has shown good form. Tiafoe recently finished playing in another tournament, which may affect his physical and emotional preparation. Therefore, we are likely to see a tough battle, and the Serbian player will likely come out on top.
Considering Tiafoe's physical and emotional fatigue after his recent match, as well as his recent loss, Kecmanovic has the advantage of freshness and adaptation to the clay court. Stability and the ability to play long rallies can help him wear down the tired Tiafoe. Given the above factors, the most likely outcome is a three-set match with a total of over 22.5 games.
