Matteo Berrettini's adventure in New York ends in the quarters.
World number 7 Casper Ruud goes to the semifinals, overtaking the Roman tennis player with a score of 6-1, 6-4, 7-6 (4) in two hours and 37 minutes of play.
The blue looked tired after the round of 16 marathon against the Spaniard Davidovich-Fokina.
Having started very badly, Berrettini tried to get back into the game from the end of the second set and in the third he also has two chances to win the partial but in the end it is in Norwegian to get the better of the tiebreak.
Now the spotlight is on the other blue who reached the quarters: tomorrow Jannik Sinner will face the Spanish Carlos Alcaraz, world number 4 and in the race (like Ruud) to become number one, after the elimination of Medvedev and Nadal from the tournament.
Sinner has won two of the previous three with the young Iberian.
