Nadal put pressure on the underdog Italian’s serve from the start but Berrettini saved six break points to set up a first set tiebreaker.

Berrettini raced out to a 4-0 lead thanks to some uncharacteristically sloppy play from the Spaniard and the 23-year-old had two set points at 4-6.

But Berrettini suddenly got tight and Nadal took advantage, wearing him down in the extended baseline rallies and capturing the set when the Italian sent a forehand long for his 20th unforced error, leading Nadal to let out a roar.

Nadal broke Berrettini on his 10th opportunity to take a 4-3 lead in the second set and cruised to the finish, absorbing Berrettini’s powerful forehands and redirecting them to his weaker backhand side to see off the first time slam semi-finalist.

Next up for Nadal is a showdown with big-serving Russian Medvedev, who was a straight sets winner over Grigor Dimitrov earlier in the day.

The pair’s only previous meeting took place in the final of last month’s Rogers Cup in Montreal, where Nadal was a 6-3 6-0 winner.

If Nadal wins the final he will be just one shy of Roger Federer’s record of 20 men’s Grand Slam titles
