MELBOURNE, Australia (AFP) — Carlos Alcaraz dropped a set before muscling his way into the Australian Open Last 16 on Friday and edge closer to becoming the youngest man in history to complete a career Grand Slam.

The 21-year-old third seed was a class above Nuno Borges with the Portuguese world No. 33 dumped out of the tournament 6-2, 6-4, 6-7 (3/7), 6-2 on Rod Laver Arena

It was Alcaraz’s first time on center court this year after being shunted to neighbouring Margaret Court Arena for his opening two matches.

With the sun shining, he revelled in the atmosphere, rattling off 54 winners and nine aces, dominating from the baseline.

“The last time I played here I lost, I really wanted to play here and get another win on Rod Laver,” said the Spaniard, a four-time Grand Slam winner who is gunning for a first title in Australia.

“It’s a privilege to feel the love here in Australia. I’m trying to play different tennis, that’s what makes me enjoy playing tennis, what makes me smile on court.”

“And to entertain the people as well, making them happy.”

He will face either Briton Jack Draper or Australia’s Aleksandar Vukic next.

Meanwhile, second seed Alexander Zverev accelerated his march with a straight-sets takedown of Briton Jacob Fearnley in the third round.

The 27-year-old German put his foot to the floor on Margaret Court Arena to sweep past his 92nd-ranked opponent 6-3, 6-4, 6-4 in two hours and two minutes.

His reward is a clash against the winner of an all-French showdown between Ugo Humbert and Arthur Fils for a place in the quarter-finals.

Victory was Zverev’s 28th Australian Open win, putting him just one behind Boris Becker for the most by a German player.

Alcaraz is bidding to become the youngest man to complete a career Grand Slam — winning all four majors — in the Open Era.

His compatriot Rafael Nadal did it in 2010 aged 24.

Should he achieve the feat, he will also rewrite the record books as the youngest champion at Melbourne Park since Novak Djokovic in 2008.

To do so he will likely have to beat the Serbian star, who he is seeded to meet in a blockbuster quarterfinal.

Alcaraz started strongly against Borges, earning an immediate break with the Portuguese player netting a backhand under pressure.

Borges, who won a maiden ATP title last season, beating the now-retired Nadal, had no answer to Alcaraz’s powerful groundstrokes and was broken again in game seven on his way to losing the set.

The 27-year-old gamely clung on in the second set to 4-4 when the Spanish star slammed a forehand winner for the break and served out with his fifth ace of the day to snare a two-set lead.

Borges was on the defence in set three, fighting off two break points from Alcaraz in an enthralling 16-point seventh game to keep the set on serve.

But he refused to lie down and it went to a tie break where he stunned the world No. 3 by winning it emphatically.

Alcaraz was riled up and after holding serve to love to open set four, he produced a magical forehand winner for a break and sprinted to the finish.
