Majchrzak had already beaten No.1 seed Felix Auger-Aliassime in the quarter-finals and followed that up with a 7-6 (7-4) 6-1 victory in 89 minutes over the Russian former world No.1.

Medvedev was playing his second match of the day, having battled past Marin Cilic 6-2 3-6 6-1, with his double-header eventually taking its toll.

The pair was evenly matched in the opening stages, but Medvedev had to hold off a break that would have secured Majchrzak the first set in the 10th game.

The Pole got an important hold himself in the following game and then eventually converted his third set point to take the lead.

It was a much smoother second set for Majchrzak, after Medvedev served to take a 1-0 lead, he failed to win another game, with his opponent reeling them off in quick succession, eventually getting over the line on his second attempt.

Majchrzak will face Alex De Minaur in the final on Monday after the Australian breezed past Adrian Mannarino in the other semi-final.

Majchrzak is just the sixth Polish man to reach an ATP Tour-level championship match in the Open Era and is looking to lift his first trophy on the professional circuit.

But that is not the only thing on the line. The world No.76 has already risen 23 spots in the ATP rankings and would break into the top 50 for the first time if he beats world No.6 De Minaur to the trophy.
