Kamil Majchrzak achieved his career-high ranking of No. 61 on the ATP Rankings in September 2025. The Pole is in great form at the moment, reaching two Round of 16s and two Round of 32s in his last four events. The 29-year-old has a success rate of under 50% throughout his career, and hasn’t won a tour-level trophy as yet. Majchrzak enjoyed a brilliant semifinal run at the Grand Prix Hassan II, before reaching a maiden Grand Slam pre-quarterfinal at Wimbledon. The World No. 70 has a win-loss record of 15-11 this year – and won both qualifying matches in straight sets.

Ben Shelton vs Kamil Majchrzak ATP Swiss Indoors Basel 2025 Prediction

A lot will depend on Ben Shelton’s preparations before this tournament. If the American can find an early rhythm on serve, he will ease into the encounter. Majchrzak will test him by attacking the backhand wing and slowing down the pace of the match. However, he will find it hard to make inroads on the Shelton serve – particularly when it comes to his sliders on the ad court. A first serve percentage in excess of 65% should get the job done for the No. 2 seed.

Prediction: Ben Shelton in straight sets.
