MELBOURNE: Ben Shelton’s Australian Open quarterfinal foe, Lorenzo Sonego, produced the shot of the tournament — diving to his left for a volley with so much spin that the ball bounced on one side of the net, then floated back over to the other — but it was the American who ended up with the victory Wednesday.
The left-handed Shelton did some entertaining of his own, including earning cheers by doing a couple of push-ups after tumbling in the concluding tiebreaker, and he reached his second Grand Slam semifinal at age 22 by beating the unseeded Sonego 6-4, 7-5, 4-6, 7-6 (4).
“I’m relieved,” said Shelton, who will meet No. 1 Jannik Sinner of Italy on Friday for a spot in the final. “Shout out Lorenzo Sonego because that was some ridiculous tennis.”
Sinner, the defending champion at Melbourne Park, completely overwhelmed the last Australian in the men’s bracket, No. 8 Alex de Minaur, 6-3, 6-2, 6-1 at night.
“It’s been too many times playing him and seeing the same thing. So I’m not even surprised anymore when I face him,” said de Minaur, who is now 0-10 against Sinner over their careers. “Matches like these happen.”
Sinner looked and played much better than he did — hand trembling, head dizzy — during a four-set struggle against Holger Rune in the fourth round. After giving himself a bit of a break on Tuesday, sleeping in and only hitting on court for about 30 or 40 minutes, Sinner said his body was much better.
“For sure, was (my) best match of the tournament so far,” said Sinner, who stretched his unbeaten winning streak to 19 matches dating back to last season.
Shelton, who is seeded 21st, closed the first set against Sonego with a 144 mph (232 kph) ace, tied for the fastest serve over the past 1 1/2 weeks, and flexed his left arm after smacking a powerful forehand to close a 22-stroke point and earn a break in the second. His father Bryan, a former tour pro who is Ben’s coach, grinned, too, while patting his own right biceps.
A few points from the end, Shelton sprinted to get his racket on a seemingly unreachable ball, and fell into a courtside advertising board as Sonego hit an easy winner to take the point.
Shelton stayed on the ground for a bit, then earned applause for his effort — and post-fall calisthenics.
When Shelton closed things with a 26th forehand winner — he had zero via backhands — he flexed again and sneered until his expression morphed into a smile.
At his news conference, Shelton offered some unprompted comments critical of some of the people handling on-court post-match interviews.
As good as Shelton is with his serves and forehands, his improving return game is a significant part of what carried him to the final four at the Australian Open for the first time.
He did just enough in that department, accumulating 11 break points and converting three, against Sonego, an Italian ranked 55th. Shelton entered the match coming through on 52 percent of his break chances, the highest rate among the eight men’s quarterfinalists.
Shelton lost to Novak Djokovic in the 2023 US Open semifinals.
The other semifinal will be Djokovic vs. No. 2 Alexander Zverev. Djokovic continued his pursuit of an 11th Australian Open title, and unprecedented 25th major trophy, by overcoming a leg injury and Carlos Alcaraz 4-6, 6-4, 6-3, 6-4 in a quarterfinal that began Tuesday night and ended at nearly 1 a.m. on Wednesday.
The women’s semifinals Thursday night are No. 1 Aryna Sabalenka, the tournament winner in each of the last two years, against No. 11 Paula Badosa, and No. 2 Iga Swiatek against No. 19 Madison Keys.
The crowd-pleasing factor was high for Shelton vs. Sonego, who never before had made it this far at a major.
Sonego went 67-for-90 on trips to the net, and his highlight-reel volley came at the outset of the second set. It was so remarkable that Shelton acknowledged the effort by offering a congratulatory handshake.
There was another terrific shot by Sonego in the fourth set, when he raced with his back to the net and spun to hit a hook shot of sorts that resulted in a winner.
It’s Shelton, though, who will get to keep playing in Melbourne this year.
