ATP Tour news: Carlos Alcaraz and Cameron Norrie on collision course at Argentina Open

US Open champion Alcaraz's comeback continued to gather steam as he dispatched Dusan Lajovic 6-4, 6-2 in his quarter-final clash.

"I think I played really, really well from the beginning until the last ball, the last point," Alcaraz said.

"I knew that it was going to be really, really difficult. Dusan is playing great on clay, [he is] a great player, a really tough one.

"I had to be really, really solid from deep in the court," he added.

"My second match of the year and I'm really happy with my performance."

The Spaniard will next face Bernabe Zapata Miralles, who knocked out home favourite Francisco Cerundolo 6-3 6-7 6-3.

Meanwhile, Norrie survived a first set scare and a pair of rain delays to also reach the last four in Buenos Aires.

The British number one dropped the opener to home favourite Tomas Martin Etcheverry but stormed back after the first break to eventually triumph 5-7 6-0 6-3.

Norrie's hopes of reaching his second tour semi-final of the season appeared in doubt as Etcheverry, the world number 82, played confidently in front of his home crowd to take the opener.

But Norrie responded by adapting his game plan and it paid off handsomely as he stormed through the second set before also maintaining the upper-hand in a decider that was also split due to showers.

Norrie will face Peruvian qualifier Juan Pablo Varillas in the semi-finals after he upset third seed Lorenzo Musetti 6-4 6-4.
