Alcaraz sees off Sonego threat to reach Australian Open third round
After fellow seeds Casper Ruud, Alexander Zverev and Cameron Norrie all huffed and puffed to five-set wins over lower-ranked opponents, the Spaniard was tested by the wind against the unseeded Sonego.
"I'm really happy with my performance today," Alcaraz said. "I think both of us played a really high level, high intensity, the match was a little bit tricky with the wind and the sun."
The double Grand Slam champion, who missed last year's tournament due to injury, took the opening set with a single break, then in the next set let Sonego off the hook in the ninth game, and was unable to recover from 5-1 down in the tie-break.
The Italian, ranked 46 in the world, won the pair's only previous clash in 2021, when Alcaraz was outside the top 50. But the Italian was put through the wringer by his vastly-improved opponent's heavy forehands to lose the third set.
In a fourth set where both players were at their entertaining best, Sonego surrendered serve early on, but Alcaraz raised his game to reel off the points in the tie-break and go through in style.
"It was tough to play your best but we tried to stay there all the time, even if I lost the second set," said Alcaraz, who will face Chinese wild card Shang Juncheng next.
