Red-hot Nakashima stuns Medvedev to reach Cincinnati fourth round

Cincinnati Open third-round match saw American Brandon Nakashima pull off an impressive upset by defeating Russian fourth seed Daniil Medvedev 6-7(3), 7-6(4), 6-1. The 22-year-old Nakashima arrived in the city in fine form, having already reached the semi-finals in Washington and claimed his first Masters 1000 title in Montreal.

The match began with Nakashima breaking Medvedev's serve to take a 4-2 lead, and he advanced within a game of the first set after a commanding rally. Medvedev, however, reclaimed the set, saving four crucial points before Nakashima broke to serve for the set. The American looked poised for victory, but Medvedev persisted, matching Nakashima shot for shot in the tiebreak and forcing a decider.

In the second set, Medvedev lost his concentration and composure, allowing Nakashima to break twice and seal his maiden triumph in four encounters with the Russian. Medvedev's previous win over Nakashima came in the Brisbane final earlier this year, and he had dominated the set statistics, winning 6-1 entering Tuesday's clash. With this victory, Nakashima's summer on hard courts has been nothing short of stellar, improving his record to 10-2 heading into the next round.

The world number 22 will next face Portuguese player Nuno Borges, who stunned Russian 13th seed Andrey Rublev with a 6-3, 6-4 upset.
