Among the unprecedented seed players that appeared earlier this week, Sina looked untouchable in five hours and 23 minutes in court.
Martinez aims to make his first-time professional fourth round, trying to cause his own astonishing frustration but opposes an opponent who lost only to the top five in his four Wimbledon appearances.
The efficiency of the sinners continuing to send his low-level opponents secured this part of his game, which left him effortlessly in the expected semi-final showdown with Novak Djokovic.
He has been driving into this stage, losing only five games against Aleksandar Vukic, seven games to Luca Nardi and never again threatened in Saturday’s threat to Martinez.
Sina lost only six points during his four-game service as he only took 37 minutes to capture the first set, which also included a medical timeout for Martinez to receive treatment for shoulder issues.
Despite physical struggles, the Spaniard provided resistance with a continuous serving at the start of the second time, and once again he was admirably running toward four breakout points after he left the court.
But he ended up being powerless to stop the sinner from finishing another game, and then the chief seed won by rushing to the finish line.
Sinner has shown significant consistency over the past 22 months, losing only 11 of 125 games since Beijing opened in September 2023.
Almost half of the defeats have held five meetings with defending Wimbledon champion Carlos Alcaraz in the past five matches and are second in the championship game.
But the Italians will increasingly believe that this excellent form will lead to his painful open-ended final defeat in avenging Alcaraz for France – if his Spanish rivals could also progress as one would expect.
