RIO DE JANEIRO, Brazil (AFP) — World No. 2 Carlos Alcaraz clawed back a break in both sets and dominated the tiebreaker to beat Dusan Lajovic 6-4, 7-6 (7/0) on Friday in the ATP Rio Open quarterfinals.

The 19-year-old Spaniard notched his third win in three matches against 32-year-old Lajovic, including a quarterfinal win over the 80th-ranked Serbian in the quarterfinals at the Argentina Open last week.

Alcaraz went on to win that title to cement his return from a four-month injury layoff that saw him miss the Australian Open.

In semifinals Saturday, Alcaraz will face Chilean Qualifier Nicolas Jarry, who toppled sixth-seeded Sebastian Baez of Argentina 6-3, 7-6 (7/3).

Alcaraz is seeking to defend the title that made him the youngest ever winner of an ATP 500 tournament last year.

Second-seeded Briton Cameron Norrie booked his semifinal berth with a 4-6, 6-1, 6-4 victory over Bolivian Hugo Dellian.

Norrie, trying to reach his third final of the year, will face Spain's Bernabe Zapata Miralles, who beat compatriot Albert Ramos Vinolas 6-4, 2-6, 6-4.

Alcaraz improved his perfect record in 2023 to 7-0, but he had to figure some things out along the way.

"It was a very complicated match," Alcaraz said. "Dusan has a great forehand, a great backhand, a great serve, very good shots, and today he has shown it, he has given a recital.
