The 27-year-old world number 10 overcame his Italian opponent in one hour and 45 minutes at the Wiener Stadthalle. De Minaur saved a set point in the opening stanza before dominating the tiebreak and cruising through the second set.

With this victory, de Minaur becomes the ninth Australian man to achieve 350 tour-level wins, joining a prestigious list that includes Lleyton Hewitt, Rod Laver, and Pat Rafter. He reached the semi-finals of the Austrian event for the third consecutive year.

De Minaur produced a strong serving performance, landing 71 percent of his first serves and out-acing Berrettini 5-4. He noted that his rhythm on serve has been a recent focus and expressed satisfaction with his execution during the match.

"That’s been an emphasis as of late, and I do feel like I’ve got in a good rhythm on serve and feel like I’m confident with what I’m doing," de Minaur said. "Today was a great serving display from me."

The victory sets up a semi-final showdown against Alexander Zverev, who advanced by defeating Arthur Fery 6-0, 6-2. Zverev is set to become the world number one on Monday and has defeated de Minaur in their recent individual meetings.

De Minaur acknowledged the challenge of facing the incoming world number one. "That’s the types of matches that you want to be playing, against the best in the world – and right now he’s the best in the world," he said.

A win against Zverev would significantly boost de Minaur’s chances of qualifying for the ATP Finals in Turin. He is currently battling for the eighth and final qualifying spot, with only the Paris Masters remaining after the Vienna tournament.

Elsewhere in the draw, Daniil Medvedev secured his place at the ATP Finals by defeating Adrian Mannarino 6-2, 6-3. Medvedev is scheduled to face Carlos Alcaraz, who overcame Tommy Paul 6-4, 7-6 (7-2) in his own quarter-final match.

The victory ensures Zverev moves one step closer to the latter stages of the hard-court event. He will now face Alejandro Davidovich Fokina in the next round of the competition after the Spaniard advanced through his respective quarter-final fixture.

Zverev acknowledged the quality of his performance after the match, noting that he felt he had significantly improved compared to his previous outings earlier in the week. The German player had required three sets to secure victories in each of his two preceding matches.

Reflecting on his display against De Minaur, Zverev expressed satisfaction with his overall level on the court. He described the display as a substantial improvement from his earlier performances as he navigated the demanding tournament schedule in Shanghai.

The first set provided a stern test for the German as he faced the renowned speed and defensive capabilities of the Australian contender. De Minaur pushed the top seed during the opening exchanges, forcing Zverev to work hard to establish any sustained rhythm from the baseline.

Zverev gradually found his range, however, utilizing a string of powerful and accurate forehands to put pressure on the Australian's service games. The decisive moment in the opening set arrived during the fifth game when the German successfully converted a crucial break point.

Despite suffering a minor hiccup with a double-fault later in the set, Zverev maintained his composure under pressure. He demonstrated resilience by saving three consecutive break points to successfully hold his own serve and maintain his narrow advantage.

The top seed then capitalized on his momentum in the tenth game to close out the opening set. Zverev secured the advantage with a delicate and well-executed backhand shot at the net, leaving his opponent with too much ground to cover.

Carrying the psychological advantage into the second set, Zverev refused to relent and maintained high pressure on De Minaur's service games. The Australian competitor battled hard to stay within touching distance of the world-class German player throughout the baseline exchanges.

The pressure finally told in the seventh game of the second set as Zverev carved out another opening. The German forced a breakpoint opportunity, which was converted when De Minaur unfortunately served the ball directly into the net.

Although the 27-year-old Australian attempted to mount a late resistance and clung on for a brief period, Zverev remained entirely focused. The top seed closed out the contest efficiently, clinching the victory on his very first match point.

The defeat brings an end to De Minaur's singles campaign at the Shanghai Masters following another combative display. The Australian had utilized his trademark court coverage to test the German seed throughout the first set before ultimately falling short.

Meanwhile, Zverev's next opponent, Alejandro Davidovich Fokina, reached the semi-finals via a premature conclusion in his quarter-final match. The Spaniard advanced when his opponent, France's Arthur Gea, was forced to retire injured after just twenty-two minutes of play.

Gea, who was competing in the biggest match of his professional career at this level, had been trailing 1-4 in the first set. The 21-year-old Frenchman called for a medical timeout to receive treatment on his lower right side before returning briefly to the court.

The qualifier ultimately decided that continuing was too great a risk for the remainder of the season. Gea explained that he had felt pain in his psoas, a muscle in the lower back, during his morning warm-up session prior to the quarter-final clash.

Despite receiving treatments and attempting to play through the discomfort, the French player realized he could not compete at full capacity. Ranked 56th in the world, Gea expressed sadness at the unfortunate end to his impressive run at the prestigious ATP 1000 event.

Zverev's progression highlights his ongoing consistency on the international tennis circuit as the season enters its closing stages. The German player continues to anchor his status among the elite competitors in men's professional tennis with another deep run at a major event.

The upcoming semi-final encounter against Davidovich Fokina will offer Zverev another opportunity to test his current form. Fans and analysts will be watching closely to see if the top seed can maintain the elevated standard he displayed against De Minaur.

The Shanghai Masters remains one of the key highlights of the autumn tennis calendar, attracting top players from around the globe. As the tournament reaches its business end, remaining competitors are vying for crucial ranking points and the prestigious title.

Both semi-finalists will now utilize the intervening period to recover and prepare tactically for the next phase of the competition. Zverev will aim to carry his current momentum forward as he targets a place in the tournament's ultimate showdown.
