My prediction: Stefanos Tsitsipas will defeat Harold Mayot 2-0. Tsitsipas has experience, a strong serve, and powerful shots, making him a versatile player. On fast courts, he can dictate play. Mayot, on the other hand, is inconsistent and has struggled against top players on hard courts. The 110-ranking gap also favors Tsitsipas. I expect a comfortable win for the Greek player.
